Mode contract

from the prompt of call 3 (editor)

Verbatim, as the agents received it: taken from the prompt of call 3 (editor), where the contract is embedded in full. This run predates the separate contract field in the record.

Hard-block primitive to instantiate: `comb_sop_2_18`   (precision INT19)
  computes: out = ax*ay + bx*by
  input ports:  ax[18], ay[19], bx[18], by[19]
  output ports: result[64]
  arithmetic: the block's operands and result are signed two's complement. A design operand narrower than its port must be widened to the port width: zero-extended if the design treats it as unsigned, sign-extended if signed. An unsigned design operand as wide as its port has no exact representation on this block.
  timing: the block is combinational; `result` is valid in the same cycle the inputs are applied (no clock port).
  Wire EVERY operand of the fused region onto the input ports (name them exactly as above); drive the region's real consumer from the output port. Tie unused term ports to 0. Do not leave input ports unconnected.

output the header + plan only.

Pick the most REPRESENTATIVE mapping — arithmetic a real designer of THIS workload would actually
map to 'comb_sop_2_18_mode', never fabricated computation. For a sum-of-products / MAC mode you must
find product terms that ALREADY feed a COMMON reduction (a shared sum/accumulator); products that
feed SEPARATE outputs (e.g. distinct systolic-array elements) must NOT be fused. An isolated scalar
multiply is NOT a representative sum-of-products target. If nothing representative exists, output
TIER: NONE.

Classify the tier of the change you propose (a datatype/algorithm variant, T3, is out of scope —
do not propose one):

T1: Direct replacement: no change to the computed function or surrounding structure; no datatype change.
T2: Local restructuring only; preserve the region's function, role, and live consumers; no new operation/datatype family.

Read the source. Output EXACTLY this header (uppercase keys), then the plan:

TIER: T1 | T2 | NONE
REGIONS: <comma-separated region id(s)> # one id for a direct swap; N ids for a fusion
SHARED_REDUCTION: <the signal/module the terms feed> # or NONE for a single region
MAPPING: <which operands map to which of the mode's ports>
PLAN: <how the module's live inputs/outputs and downstream consumers are preserved; any introduced
operations/datatypes (should be NONE for T1/T2); and the main risks>

response

2 paragraph breaks restored by the export, where the recorder joined text blocks with no separator.

I'll start by examining the source file, focusing on the candidate regions.

Now let me read the two key candidate modules.

TIER: T1
REGIONS: dsp_block_16_8_false.$mul$dla_like.small.v:11745$1166, dsp_block_16_8_false.$mul$dla_like.small.v:11745$1167
SHARED_REDUCTION: The + reduction on line 11745 of dsp_block_16_8_false that forms resulta_tmp (24-bit MAC result) — both products are summed into the same node, which drives resulta/chainout, then dot_product_16_8_30_2.o_result → processing_element.DP_res_* → accumulator_24_30_3.i_result. 72 instances (12 processing_element × 6 dot_product_16_8_30_2 × 1 dsp_block_16_8_false).
MAPPING: ax_reg[15:0] → ax[18] (zero-extend by 2, {2'b00, ax_reg}); ay_reg[7:0] → ay[19] (zero-extend by 11); bx_reg[15:0] → bx[18] (zero-extend by 2); by_reg[7:0] → by[19] (zero-extend by 11); result[63:0] → the left operand of the retained + chainin adder, whose sum is truncated into resulta_tmp[23:0] exactly as today. No term ports are left over (both product slots are used), so no tie-offs are required.

PLAN:

Why this region. dsp_block_16_8_false is the arithmetic heart of the DLA systolic datapath and is already written as a two-term sum of products: resulta_tmp <= ax_reg*ay_reg + bx_reg*by_reg + chainin;. The module even carries an int_sop_2 hard-macro instantiation under `ifdef complex_dsp , i.e. the design's author explicitly intended this to be a DSP SOP block; the behavioral `else branch (lines 11726–11749) is the path a synthesizer without complex_dsp sees, and that is where the two candidate $mul regions live. Both products feed one shared adder node — the canonical fusion target.

Why not the other candidates. winograd_dsp_16 ($733, $734) computes resa_reg <= ay_reg*coefa and resb_reg <= by_reg*coefb. These are two independent constant-coefficient multiplies driving two separate module outputs (resulta, resultb) that fan out to different Winograd transform lanes. There is no shared reduction, so fusing them into one comb_sop_2_18 would fabricate a sum that does not exist in the design. Excluded per the rules.

Edit (single module, applies to all 72 instances). In the `else branch of dsp_block_16_8_false:

Add wire [63:0] sop_result; and instantiate comb_sop_2_18 combinationally, driven by the existing input pipeline registers ax_reg/ay_reg/bx_reg/by_reg (zero-extended as in MAPPING).
Replace the RHS on line 11745 with resulta_tmp <= sop_result + chainin;.
Leave ax_reg…by_reg capture, the aclr reset arm, assign resulta = resulta_tmp; and assign chainout = {40'b0, resulta_tmp}; untouched.
Leave the `ifdef complex_dsp / int_sop_2 branch untouched.

Function preservation. Verilog + is left-associative, so the original expression already parses as ((ax_reg*ay_reg) + (bx_reg*by_reg)) + chainin. The hard block replaces exactly the parenthesized subtree; the + chainin adder and its operand order are unchanged — this is a subtree swap, not a re-association, hence T1. All operands are unsigned and strictly narrower than their ports (16 < 18, 8 < 19), so zero-extension into the signed ports is exact and both products are non-negative. Max sum is 2·(2^16−1)(2^8−1) ≈ 3.34e7, far inside 64 bits, so sop_result is bit-identical to the 64-bit value the original expression produced before the chainin add, and the final truncation to resulta_tmp[23:0] is preserved (truncation commutes with modular addition).

Timing / structure preservation. The block is combinational and is inserted between the existing ax_reg…by_reg stage and the existing resulta_tmp stage, so latency stays at 2 cycles, aclr behavior is unchanged, and the chainin/chainout chaining contract, module port list, and all downstream consumers (dot_product_16_8_30_2.o_result → accumulator_24_30_3, which sign-extends bit 23) are untouched. No new operations or datatypes are introduced.

Risks.

Signedness mismatch: the RTL multiplies are unsigned while accumulator_24_30_3 sign-extends i_result[23]. This pre-existing inconsistency is deliberately not fixed — zero-extension reproduces the current bit-exact behavior; sign-extending instead would silently change results.
Extension direction: using sign-extension on ax/bx would corrupt any feature value with bit 15 set. Must be zero-extend.
Truncation: must slice sop_result into the 64-bit add and let the 24-bit assignment truncate; taking result[23:0] first is also equivalent but the full-width form is safer to reason about.
ena port: unused in the behavioral branch today and stays unused — no change.
Blast radius is 72 instantiations from one module edit; a mistake is uniform and will show up immediately in any dot-product-level check.

Want me to hand this plan to the reviewer subagent before any implementation?

You are an INDEPENDENT, fair Reviewer. You did not write this plan. Judge it on merit.
Target mode: comb_sop_2_18_mode Tier: T1 Rule: Direct replacement: no change to the computed function or surrounding structure; no datatype change.
Region: dsp_block_16_8_false.$mul$dla_like.small.v:11745$1166 (op 'sop', datatype int16, consumers ['dsp_block_16_8_false']).
APPROVE the plan if it is correct and representative — a legitimate adaptation does not need to
be perfect, only sound. Do NOT demand rewrites for style, minor wording, or hypothetical concerns.
REVISE ONLY for a CONCRETE, specific violation you can name: (a) it changes the computed function
when the tier forbids it; (b) it introduces an operation/datatype absent from the design and not
admitted by the tier; (c) it fabricates terms to match a mode's n_terms (products that did not
exist / do not share a reduction); (d) it wires the mode to constants or a dead sink (mode island).
If none of these apply, APPROVE.
Your FIRST line must be exactly 'APPROVE' or 'REVISE', nothing else. If REVISE, the next lines
must name the specific violation (a/b/c/d) and what to change.

--- PLAN ---
I'll start by examining the source file, focusing on the candidate regions.

Now let me read the two key candidate modules.

PLAN:

Edit (single module, applies to all 72 instances). In the `else branch of dsp_block_16_8_false:

Add wire [63:0] sop_result; and instantiate comb_sop_2_18 combinationally, driven by the existing input pipeline registers ax_reg/ay_reg/bx_reg/by_reg (zero-extended as in MAPPING).
Replace the RHS on line 11745 with resulta_tmp <= sop_result + chainin;.
Leave ax_reg…by_reg capture, the aclr reset arm, assign resulta = resulta_tmp; and assign chainout = {40'b0, resulta_tmp}; untouched.
Leave the `ifdef complex_dsp / int_sop_2 branch untouched.

Risks.

Signedness mismatch: the RTL multiplies are unsigned while accumulator_24_30_3 sign-extends i_result[23]. This pre-existing inconsistency is deliberately not fixed — zero-extension reproduces the current bit-exact behavior; sign-extending instead would silently change results.
Extension direction: using sign-extension on ax/bx would corrupt any feature value with bit 15 set. Must be zero-extend.
Truncation: must slice sop_result into the 64-bit add and let the 24-bit assignment truncate; taking result[23:0] first is also equivalent but the full-width form is safer to reason about.
ena port: unused in the behavioral branch today and stays unused — no change.
Blast radius is 72 instantiations from one module edit; a mistake is uniform and will show up immediately in any dot-product-level check.

Want me to hand this plan to the reviewer subagent before any implementation?

response

APPROVE

Verification against the source (dla_like.small.v) and the T1 rule:

(a) Function unchanged — OK. Line 11745 reads resulta_tmp <= ax_reg * ay_reg + bx_reg * by_reg + chainin;. Verilog left-associativity means the two products are already a distinct subtree; replacing exactly that subtree and keeping + chainin and the 24-bit truncating assignment preserves bit-exact behavior. Operands are unsigned [15:0]/[7:0], so zero-extension into the wider (signed) mode ports is exact and products stay non-negative; max ~3.34e7 fits trivially. Insertion between the existing *_reg stage and the resulta_tmp stage keeps latency at 2 cycles and aclr semantics intact.
(b) No new op/datatype — OK. Still int16×int8 products summed; no widening of the stored result, no signedness change (the plan explicitly declines to "fix" the pre-existing zero-extend-vs-i_result[23]-sign-extend inconsistency in accumulator_24_30_3, line 11986 — correct call for T1).
(c) No fabricated terms — OK. Both products exist in the RTL and share the same + reduction node. The exclusion of winograd_dsp_16 is correct: resa_reg/resb_reg (lines 8913–8915) drive two separate outputs with no shared sum, so fusing them would have been a fabrication.
(d) No mode island — OK. Driven by the real ax_reg…by_reg pipeline, output reaches resulta/chainout → dot_product_16_8_30_2.o_result → accumulator_24_30_3. No constant tie-offs, both term slots used, live sink.

The ifdef complex_dsp branch being left alone is also right — the behavioral else branch is where the flagged $mul regions live. No concrete violation; approving.

Edit dla_like.small.v in this directory. Direct replacement: map the existing arithmetic onto the mode's primitive with no change to the computed function or the surrounding structure.

Goal: rewrite the RTL so the hard-block mode 'comb_sop_2_18_mode' is exercised in the packed netlist,
doing real work, while preserving the design's behaviour and role.
Tier: T1

Hard-block primitive to instantiate: comb_sop_2_18 (precision INT19)
computes: out = ax*ay + bx*by
input ports: ax[18], ay[19], bx[18], by[19]
output ports: result[64]
arithmetic: the block's operands and result are signed two's complement. A design operand narrower than its port must be widened to the port width: zero-extended if the design treats it as unsigned, sign-extended if signed. An unsigned design operand as wide as its port has no exact representation on this block.
timing: the block is combinational; result is valid in the same cycle the inputs are applied (no clock port).
Wire EVERY operand of the fused region onto the input ports (name them exactly as above); drive the region's real consumer from the output port. Tie unused term ports to 0. Do not leave input ports unconnected.

This is a MULTI-REGION fusion: aggregate these 2 product regions — dsp_block_16_8_false.$mul$dla_like.small.v:11745$1166, dsp_block_16_8_false.$mul$dla_like.small.v:11745$1167 — which already feed the common reduction 'The + reduction on line 11745 of dsp_block_16_8_false that forms resulta_tmp (24-bit MAC result) — both products are summed into the same node, which drives resulta/chainout, then dot_product_16_8_30_2.o_result → processing_element.DP_res_* → accumulator_24_30_3.i_result. 72 instances (12 processing_element × 6 dot_product_16_8_30_2 × 1 dsp_block_16_8_false).', into one 2-term 'comb_sop_2_18_mode' instance. Fuse only these existing terms; do not invent new ones.
Rules: edit Verilog source only; preserve the module's live inputs/outputs and its downstream
consumers; do not introduce operations or datatypes absent from the design unless this tier
admits a variant; keep the surrounding design unchanged for T1/T2. Do not fabricate terms merely
to match a mode's n_terms — that is not representative.

Follow this approved plan:
I'll start by examining the source file, focusing on the candidate regions.

Now let me read the two key candidate modules.

PLAN:

Edit (single module, applies to all 72 instances). In the `else branch of dsp_block_16_8_false:

Add wire [63:0] sop_result; and instantiate comb_sop_2_18 combinationally, driven by the existing input pipeline registers ax_reg/ay_reg/bx_reg/by_reg (zero-extended as in MAPPING).
Replace the RHS on line 11745 with resulta_tmp <= sop_result + chainin;.
Leave ax_reg…by_reg capture, the aclr reset arm, assign resulta = resulta_tmp; and assign chainout = {40'b0, resulta_tmp}; untouched.
Leave the `ifdef complex_dsp / int_sop_2 branch untouched.

Risks.

Signedness mismatch: the RTL multiplies are unsigned while accumulator_24_30_3 sign-extends i_result[23]. This pre-existing inconsistency is deliberately not fixed — zero-extension reproduces the current bit-exact behavior; sign-extending instead would silently change results.
Extension direction: using sign-extension on ax/bx would corrupt any feature value with bit 15 set. Must be zero-extend.
Truncation: must slice sop_result into the 64-bit add and let the 24-bit assignment truncate; taking result[23:0] first is also equivalent but the full-width form is safer to reason about.
ena port: unused in the behavioral branch today and stays unused — no change.
Blast radius is 72 instantiations from one module edit; a mistake is uniform and will show up immediately in any dot-product-level check.

Want me to hand this plan to the reviewer subagent before any implementation?

Work iteratively IN THIS SESSION: after each edit, run bash check.sh dla_like.small.v and read its output; if it does not synthesize, fix the RTL and check again. Do NOT run place-and-route or any VTR/vpr command — that is verified separately. Stop when check.sh reports it synthesizes cleanly with the intended arithmetic.

response

2 paragraph breaks restored by the export, where the recorder joined text blocks with no separator.

I'll start by examining the file and the target module.

Yosys tolerates the undefined blackbox (same convention as the existing raygentop adaptation). Now the edit:

Now verify the cell census in the affected module and that the block is really wired:72 instances survive flatten; opt_clean, matching the predicted 12×6×1. Now a functional equivalence check against the behavioral model:

// comb_sop_2_18.v — behavioral model of comb_sop_2_18, a PROJECT-ADDED combinational two-term
// sum-of-products hard-block mode (arch mode comb_sop_2_18_mode). This mode does not exist
// upstream; it is defined in the working arch copy
// (benchadapt/arch/k6FracN10LB_mem20K_complexDSP_customSB_22nm.xml, the comb_sop_2_18 <model>
// and the comb_sop_2_18_mode <mode>) and in configs/target/comb_sop_2.json. It takes its
// operand widths from the arch's own int_sop_2 / sop_2_mode (18, 19, 18, 19) but is
// combinational and has no reset, mode_sigs, chain or scan ports. There is no silicon, no
// COFFE characterization, and no Koios soft substitute for THIS block; the three project
// files ARE the definition, and this model is written to match them.
//
// KNOWN (from the arch working copy, by construction):
//   ports  ax[18], ay[19], bx[18], by[19] -> result[64]; no other ports; no clock on the
//          model or the pb_type
//   timing delay_constant only (2.14e-9, copied from mult_add_mode_18_19_36 as for
//          comb_mult_add_16); no T_setup / T_clock_to_Q -> latency 0 cycles, combinational
//   result = ax*ay + bx*by (metadata expression), precision INT19
//
// ASSUMPTION (a definition choice, not a measurement; the arch cannot express it):
//   S1 signedness — signed (two's complement) on ax, ay, bx, by, as the spec states
//      ("signed": true). Modeled with signed operands throughout: each 18x19 product is
//      exact in 37 bits (|ax*ay| <= 2^17 * 2^18 = 2^35), the two-product sum is formed at
//      64 bits signed and is exact (|ax*ay + bx*by| <= 2^36, i.e. 38 bits signed), so
//      result carries the full sum with no truncation.

prompt

You are an INDEPENDENT ACCEPTANCE REVIEWER — the gate of record for whether an adapted design is
a LEGITIMATE member of its benchmark suite. You did NOT plan or write this edit. Judge only what
is in front of you. Your verdict is final and fully automated; there is no human backstop, so err
toward rejecting anything you cannot positively ground.

FRAMING — refute by default. Your job is to find why this adaptation is NOT a legitimate suite
member. Assume it is contrived until the evidence shows otherwise. A rewrite that merely "makes
the mode appear in the netlist" is NOT sufficient — the mode must do real work the original
workload actually implied.

This case has already passed the deterministic structural, provenance, and (for T3) evidence
gates — do not re-litigate those mechanically. Your judgement is the legitimacy call they
cannot make: would a real designer of THIS workload ship this, or is it a mode-island / fabricated
dot-product / gratuitous variant dressed up to pass?

REJECT if any of these hold:

(a) FABRICATED TERMS — a fused N-term product/sum aggregates operands that did not genuinely
share a reduction in the original; the "dot product" is manufactured to fill the mode's arity.
(b) MODE ISLAND / DEAD WORK — the mode's result does not flow to the design's real outputs, or
is wired to constants / a sink that the rest of the design ignores.
(c) ROLE BREAK — the adapted region no longer plays the workload role the witness recorded
(e.g. a control-path multiply repurposed as a fake datapath MAC).
(d) UNGROUNDED VARIANT (T3) — the precision/algorithm variant is not the one the cited sibling
design evidences; the adaptation drifts to a workload character the suite does not contain.

ACCEPT if the adaptation is sound: the mapped arithmetic genuinely existed, the fused terms really
shared a reduction, the mode's output drives the original consumers, and the workload role is
preserved. Legitimate adaptation need not be optimal — only real.

You MUST ground your verdict: cite the specific preserved role (from the witness), the real
region(s)/reduction the mode maps onto, and — for T3 — the sibling evidence axis. A verdict you
cannot ground is a REJECT.

response

1 paragraph break restored by the export, where the recorder joined text blocks with no separator.

I'll examine the actual file to ground my verdict rather than judging the diff in isolation.

Role preserved (witness dsp_block_16_8_false, op sop, int16). The module is still a 2-cycle MAC in the PE datapath: the ax_reg..by_reg input register stage and the resulta_tmp output register stage are both untouched, aclr still zeroes all five registers, chainin is still added, and resulta/chainout are still driven from resulta_tmp. The diff is 19 lines confined to this one `else (soft) branch; nothing else in the file changed.

Real region / real shared reduction — not fabricated (rebuts (a)). The witness's two regions are literally the two operands of one + on pristine line 11745: resulta_tmp <= ax_reg * ay_reg + bx_reg * by_reg + chainin;. Both products already summed into the same node in the original source. The mode's arity is 2 and exactly 2 genuine products were fused — no zero-padding, no operand imported from an unrelated reduction. The residual + chainin is correctly left soft rather than over-claimed into the block.

The decisive grounding is the design's own `ifdef complex_dsp branch immediately above (lines 11713–11726), which instantiates int_sop_2 with .ax/.ay/.bx/.by/.chainin/.result/.chainout for this same module. The workload author already declared this block to be a two-term sum-of-products DSP; comb_sop_2_18 is defined (per verify/models/comb_sop_2_18.v) to take its widths 18/19/18/19 from that very int_sop_2/sop_2_mode. This is the mode's intended target, not a repurposing.

Not a mode island (rebuts (b)). Traced end-to-end in the file: sop_result → resulta_tmp → resulta (and chainout) → dot_product_16_8_30_2.o_result (line 11690) → DP_res_0..5 (lines 11431–11488) → accumulator_24_30_3.i_result (lines 11491–11534). The module is instantiated once per dot_product, 6 per processing_element, 12 PEs = the witness's 72 instances, all covered by the single module-level edit.

No role break (rebuts (c)). This was a datapath MAC before and is a datapath MAC after; no control-path signal was recruited.

(d) N/A — T1, manifest introduces no operations or datatypes, no precision/algorithm variant.

Semantics verified, not just asserted. I simulated the pristine expression against the replacement using the project's own behavioral model (200,000 random vectors plus the all-ones corner, random 64-bit chainin): 0 mismatches. The zero-extension is exact — 16-bit into signed 18-bit and 8-bit into signed 19-bit both stay positive, so the signed block computes the same non-negative products, and sop_result + chainin truncated to 24 bits is bit-identical to the original 64-bit-context expression.

One observation, not grounds for rejection: at the only instantiation site chainin is tied to 64'd0 (line 11686), so the surviving soft adder collapses under synthesis — the hard block ends up doing essentially all the arithmetic work of this MAC. That strengthens rather than weakens the case.

(Scratch simulation files were removed; the reviewed dla_like.small.v was not modified.)

1 editor attempt(s) · from the outcome record · final: accepted

This run predates the per-attempt record (2026-09-12). With a single editor attempt, the rows below follow directly from the recorded outcome code and reason; nothing is inferred beyond what that code implies about the stages that ran.

Checks on the final editor attempt

Stage results follow from the outcome code (the record stores the code and the failure reasons, not a per-check list). The deterministic gate evaluates every check and records every failure, so any check not named in a failure reason passed.

Reviewer verdict text call 4 · ACCEPT

I'll examine the actual file to ground my verdict rather than judging the diff in isolation.ACCEPT

**Role preserved (witness `dsp_block_16_8_false`, op `sop`, int16).** The module is still a 2-cycle MAC in the PE datapath: the `ax_reg..by_reg` input register stage and the `resulta_tmp` output register stage are both untouched, `aclr` still zeroes all five registers, `chainin` is still added, and `resulta`/`chainout` are still driven from `resulta_tmp`. The diff is 19 lines confined to this one `` `else `` (soft) branch; nothing else in the file changed.

**Real region / real shared reduction — not fabricated (rebuts (a)).** The witness's two regions are literally the two operands of one `+` on pristine line 11745: `resulta_tmp <= ax_reg * ay_reg + bx_reg * by_reg + chainin;`. Both products already summed into the same node in the original source. The mode's arity is 2 and exactly 2 genuine products were fused — no zero-padding, no operand imported from an unrelated reduction. The residual `+ chainin` is correctly left soft rather than over-claimed into the block.

The decisive grounding is the design's *own* `` `ifdef complex_dsp `` branch immediately above (lines 11713–11726), which instantiates `int_sop_2` with `.ax/.ay/.bx/.by/.chainin/.result/.chainout` for this same module. The workload author already declared this block to be a two-term sum-of-products DSP; `comb_sop_2_18` is defined (per `verify/models/comb_sop_2_18.v`) to take its widths 18/19/18/19 from that very `int_sop_2`/`sop_2_mode`. This is the mode's intended target, not a repurposing.

**Not a mode island (rebuts (b)).** Traced end-to-end in the file: `sop_result` → `resulta_tmp` → `resulta` (and `chainout`) → `dot_product_16_8_30_2.o_result` (line 11690) → `DP_res_0..5` (lines 11431–11488) → `accumulator_24_30_3.i_result` (lines 11491–11534). The module is instantiated once per `dot_product`, 6 per `processing_element`, 12 PEs = the witness's 72 instances, all covered by the single module-level edit.

**No role break (rebuts (c)).** This was a datapath MAC before and is a datapath MAC after; no control-path signal was recruited.

**(d) N/A — T1, manifest introduces no operations or datatypes, no precision/algorithm variant.**

**Semantics verified, not just asserted.** I simulated the pristine expression against the replacement using the project's own behavioral model (200,000 random vectors plus the all-ones corner, random 64-bit `chainin`): **0 mismatches**. The zero-extension is exact — 16-bit into signed 18-bit and 8-bit into signed 19-bit both stay positive, so the signed block computes the same non-negative products, and `sop_result + chainin` truncated to 24 bits is bit-identical to the original 64-bit-context expression.

One observation, not grounds for rejection: at the only instantiation site `chainin` is tied to `64'd0` (line 11686), so the surviving soft adder collapses under synthesis — the hard block ends up doing essentially all the arithmetic work of this MAC. That strengthens rather than weakens the case.

(Scratch simulation files were removed; the reviewed `dla_like.small.v` was not modified.)

Synthesis-only result (counted from files)

No synthesis-only stage directory in this run dir (the stage was added to the loop after this run, or the mode is not macro-backed). The synthesis netlist of the full VTR flow is counted instead:

file	target macro instances
`vtr/dla_like.small/dla_like.small.parmys.blif`	72 × `comb_sop_2_18`

Packed netlist (counted from files)

Counted at export time from the .net file(s) in the run dir: occurrences of mode="…" for the target mode, one per packed block in that mode.

attempt	file	target mode present	blocks in target mode
(shared dir)	`vtr/dla_like.small/dla_like.small.net`	yes	72

This run used one VTR directory for all editor attempts, so only the last launch that wrote a netlist is on disk.

This run predates the VPR-arguments record, so its regime is inferred as legacy (VPR defaults), which every run before 2026-09-12 used. A lower delta is better on every row.
