finished: 2026-08-27 15:31:53 -0700
suite / design: vtr_demo / raygentop
target mode: sop_4_mode
tier: needs restructuring (T2) — the region did not fit the mode as is
outcome: ACCEPTED — reviewer agent confirmed
editor attempts: 1 (editor calls against the one approved plan; record field iterations)
wall clock: 2m 6s (agents 1m 42s, VTR and other 24s) [126.4 s total; 'other' is synthesis-only checks and framework time between calls]
models per role: planner: opencode-go/gpt-5.6-luna
reviewer:plan: opencode-go/gpt-5.6-luna
editor: opencode-go/gpt-5.6-luna
reviewer:acceptance: opencode-go/gpt-5.6-luna
VPR arguments: not recorded (this run predates the vpr record in run.json)
repo commit: not recorded (runs before 2026-09-12 carry no commit)
sandbox: not recorded (run made before the agent sandbox existed; its agent calls were not confined)
agent reads: editor read the framework repository (paths each agent named outside its own working directory, computed from the tool events; its own scratch excluded)
prompt set: not recorded (runs before 2026-09-13 carry no prompt-set hash)

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: `int_sop_4`   (precision INT9)
  computes: out = ax*ay + bx*by + cx*cy + dx*dy
  input ports:  clk[1] (clock), reset[1], mode_sigs[12], ax[9], ay[9], bx[9], by[9], cx[9], cy[9], dx[9], dy[9], chainin[64]
  output ports: result[64], chainout[64]
  timing: `result` is registered inside the block on `clk`; it is valid 1 cycle after the input operands are applied.
  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.

prompt

You are the Planner. Choose the best region(s) in raygentop.v to adapt so hard-block mode
'sop_4_mode' (Hard-block primitive to instantiate: int_sop_4 (precision INT9)
computes: out = ax*ay + bx*by + cx*cy + dx*dy
input ports: clk[1] (clock), reset[1], mode_sigs[12], ax[9], ay[9], bx[9], by[9], cx[9], cy[9], dx[9], dy[9], chainin[64]
output ports: result[64], chainout[64]
timing: result is registered inside the block on clk; it is valid 1 cycle after the input operands are applied.
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.) is exercised, then write a concrete plan. Do NOT edit files —
output the header + plan only.

Pick the most REPRESENTATIVE mapping — arithmetic a real designer of THIS workload would actually
map to 'sop_4_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

TIER: T2
REGIONS: bilinearintrp.$mul$raygentop.v:2874$348, bilinearintrp.$mul$raygentop.v:2875$349, bilinearintrp.$mul$raygentop.v:2876$350
SHARED_REDUCTION: bilinearintrp signal r = i1r + i2r + i3r
MAPPING: ax={1'b0,ul}, ay={2'b0,rul}, bx={1'b0,vl}, by={2'b0,rvl}, cx={1'b0,wl}, cy={2'b0,rwl}, dx=9'b0, dy=9'b0; mode_sigs=12'b0, chainin=64'b0, reset tied inactive, clk=clk
PLAN: Replace the three registered red-channel products and their shared sum with one int_sop_4 instance. Drive r from result[6:0], preserving the existing live consumer and truncation; retain the green and blue paths unchanged. Use the already registered ul/vl/wl and color weights so the primitive’s registered result preserves timing. Introduce no operations or datatypes. Main risks are reset polarity/initial-state equivalence, signedness and width-extension semantics, and confirming the primitive’s result slice matches the existing assignment.

prompt

You are an INDEPENDENT, fair Reviewer. You did not write this plan. Judge it on merit.
Target mode: sop_4_mode Tier: T2 Rule: Local restructuring only; preserve the region's function, role, and live consumers; no new operation/datatype family.
Region: bilinearintrp.$mul$raygentop.v:2874$348 (op 'sop', datatype int8, consumers ['bilinearintrp']).
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 ---
TIER: T2
REGIONS: bilinearintrp.$mul$raygentop.v:2874$348, bilinearintrp.$mul$raygentop.v:2875$349, bilinearintrp.$mul$raygentop.v:2876$350
SHARED_REDUCTION: bilinearintrp signal r = i1r + i2r + i3r
MAPPING: ax={1'b0,ul}, ay={2'b0,rul}, bx={1'b0,vl}, by={2'b0,rvl}, cx={1'b0,wl}, cy={2'b0,rwl}, dx=9'b0, dy=9'b0; mode_sigs=12'b0, chainin=64'b0, reset tied inactive, clk=clk
PLAN: Replace the three registered red-channel products and their shared sum with one int_sop_4 instance. Drive r from result[6:0], preserving the existing live consumer and truncation; retain the green and blue paths unchanged. Use the already registered ul/vl/wl and color weights so the primitive’s registered result preserves timing. Introduce no operations or datatypes. Main risks are reset polarity/initial-state equivalence, signedness and width-extension semantics, and confirming the primitive’s result slice matches the existing assignment.

prompt

Edit raygentop.v in this directory. Local restructuring: re-express the region (e.g. a multiply array + adder tree as a fused sum-of-products) to reach the mode; preserve the region's function and role, keep the rest of the design unchanged, wire the mode's real consumers.

Goal: rewrite the RTL so the hard-block mode 'sop_4_mode' is exercised in the packed netlist,
doing real work, while preserving the design's behaviour and role.
Tier: T2

Hard-block primitive to instantiate: int_sop_4 (precision INT9)
computes: out = ax*ay + bx*by + cx*cy + dx*dy
input ports: clk[1] (clock), reset[1], mode_sigs[12], ax[9], ay[9], bx[9], by[9], cx[9], cy[9], dx[9], dy[9], chainin[64]
output ports: result[64], chainout[64]
timing: result is registered inside the block on clk; it is valid 1 cycle after the input operands are applied.
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 4 product regions — bilinearintrp.$mul$raygentop.v:2874$348, bilinearintrp.$mul$raygentop.v:2875$349, bilinearintrp.$mul$raygentop.v:2876$350 — which already feed the common reduction 'bilinearintrp signal r = i1r + i2r + i3r', into one 4-term 'sop_4_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:
TIER: T2
REGIONS: bilinearintrp.$mul$raygentop.v:2874$348, bilinearintrp.$mul$raygentop.v:2875$349, bilinearintrp.$mul$raygentop.v:2876$350
SHARED_REDUCTION: bilinearintrp signal r = i1r + i2r + i3r
MAPPING: ax={1'b0,ul}, ay={2'b0,rul}, bx={1'b0,vl}, by={2'b0,rvl}, cx={1'b0,wl}, cy={2'b0,rwl}, dx=9'b0, dy=9'b0; mode_sigs=12'b0, chainin=64'b0, reset tied inactive, clk=clk
PLAN: Replace the three registered red-channel products and their shared sum with one int_sop_4 instance. Drive r from result[6:0], preserving the existing live consumer and truncation; retain the green and blue paths unchanged. Use the already registered ul/vl/wl and color weights so the primitive’s registered result preserves timing. Introduce no operations or datatypes. Main risks are reset polarity/initial-state equivalence, signedness and width-extension semantics, and confirming the primitive’s result slice matches the existing assignment.

Work iteratively IN THIS SESSION: after each edit, run bash check.sh raygentop.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

Updated raygentop.v:

Replaced the three red-channel products and reduction with one int_sop_4.
Wired all operands, mode signals, chain input, clock, and inactive reset.
Connected r to sop_result[6:0].
Preserved green/blue paths and downstream behavior.

Verification: bash check.sh raygentop.v reports OK: synthesizes cleanly.

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.

Your FIRST line must be exactly 'ACCEPT' or 'REJECT'. Then, on the following lines, state the
grounding (role preserved / real region mapped / sibling evidence) or the specific violation
(a/b/c/d) and what makes it illegitimate.

Read these files in this directory: raygentop.v

response

The bilinearintrp role is preserved. The mode maps the three genuine red-channel products from regions $2874$348, $2875$349, and $2876$350 onto the original reduction i1r + i2r + i3r; the fourth SOP lane is zero padding, not a fabricated operand. sop_result[6:0] drives the original r output consumed by bilinearintrp. No T3 sibling evidence is required because this is T2 with no variant introduced.

Verification

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.

Editor attempts

attempt	editor call	result
1	call 3 (ok)	accepted — reviewer agent confirmed

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.

stage	result	detail
synthesis-only check	passed	target macro was emitted by synthesis (the loop only continues to VTR when it is)
deterministic checks (structural, provenance, per-tier)	passed
evidence floor (whole-design variants only)	passed	not applicable to a direct swap or a restructuring (passes through)
acceptance reviewer (gate of record)	accepted	call 4: ACCEPT

Reviewer verdict text call 4 · ACCEPT

ACCEPT

The `bilinearintrp` role is preserved. The mode maps the three genuine red-channel products from regions `$2874$348`, `$2875$349`, and `$2876$350` onto the original reduction `i1r + i2r + i3r`; the fourth SOP lane is zero padding, not a fabricated operand. `sop_result[6:0]` drives the original `r` output consumed by `bilinearintrp`. No T3 sibling evidence is required because this is T2 with no variant introduced.

Synthesis-only result (counted from files)

attempt	file	target macro instances
-	`vtr/synth/raygentop/raygentop.parmys.blif`	1 × `int_sop_4`

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/raygentop/raygentop.net`	yes	1

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

Baseline: the unmodified raygentop through the same flow under the legacy settings regime (channel width minimum-width search, device auto, seed 1, grid 24 x 24 (auto), routed at width 88); measured, 2026-09-12 18:35:39 -0700, from configs/baselines/complexDSP.yaml. 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.

Read from the VPR log of the accepted attempt when the run finished (outcome.json ppa). Runs before 2026-09-12 recorded PPA only on acceptance.

Coverage

Not recorded (runs before 2026-09-12 carry no coverage counts).
