Predecessor: L-DPC27 Wave-30 — CLOSED 2026-05-15, W30-G0 ✅ (trinity-fpga#109)

0. R5-HONEST disclaimer

Wave-31 = portability probe wave, not a tape-out wave. PDK portability is a constraint-only/synthesis-only assertion until silicon return. SG13G3 (IHP 130 nm open PDK) and SKY90 (SkyWater 90 nm proxy) targets are gates, not claims. Refuted by synthesis if any RTL surface fails to map on either PDK without * reintroduction.


1. Hypothesis H_W31 (pre-registered, R7 falsification gate)

H_W31 (Lever #6 — multi-PDK portability):
  All 4 merged RTL surfaces (Lane V LUT PE 91c164ac,
  Lane W BitROM bank 898fc06, Lane V' 2x2 mesh 2a06e540,
  Lane S sparsity 24 98246bd3) synthesise on BOTH
  SG13G3 (IHP 130 nm) AND SKY90 (SkyWater 90 nm proxy)
  liberty constraints without introducing * operators.

REFUTED IF (any one):
  - any surface fails to synthesise on SG13G3, OR
  - any surface fails to synthesise on SKY90, OR
  - any surface introduces * operator to meet constraints, OR
  - any sacred-ROM cell is altered between PDKs (R18).

DEADLINE: 2026-07-31 (pre-silicon multi-PDK synth verdict); silicon TTIHP27a 2026-09-30.

2. Two-lane lane map

Lane M — pdk-portability-probe — PRIMARY

  • Spec: Add Yosys synth targets for SG13G3 + SKY90 (using open Liberty files / placeholder tech-mappings if no Liberty is committable). Emit per-surface per-PDK gate-count + area-proxy table. R-SI-1 grep on post-synth netlist for both PDKs.
  • Repo: gHashTag/tt-trinity-holo
  • Files: sim/pdk_portability/{Makefile,sg13g3_tech.lib,sky90_tech.lib,report.md}, docs/lever-stack/lane-m.md
  • Effort: S · R5-HONEST: report.md labels 🟡 SYNTH-SIM and notes Liberty-proxy gap

Lane J — coq-pdk-witness — formal proof

  • Spec: Add trios-coq/IGLA/PdkPortable.v to gHashTag/t27 proving that PDK retargetting does not introduce * to the holo_op alphabet. Pattern: extend the chain holographic_no_star → sparsity_24_safe → timing_400mhz_safe → pdk_portable_safe.
  • Repo: gHashTag/t27
  • Files: trios-coq/IGLA/PdkPortable.v + _CoqProject update + NOW.md entry
  • Effort: S

3. Success criteria (verification matrix)

Gate Predicate Lane
W31-G0 Both lanes merge with substantive CI green M, J
W31-G1 All 4 surfaces synth-clean on SG13G3 Lane M
W31-G2 All 4 surfaces synth-clean on SKY90 Lane M
W31-G3 Zero * in either PDK netlist Lane M
W31-G4 pdk_portable_safe Qed (no admit) Lane J

4. Quantum Brain Wave Question

  1. Which 1:1 mapping does this wave add? — PHYS→SI extended across multiple silicon processes. The same 75-cell Sacred ROM maps 1:1 to SG13G3 130 nm AND SKY90 90 nm AND TTIHP27a — proving the mapping is process-agnostic.
  2. Which conjectured constants move toward measured? — Process-portability constants (gate counts, area-proxy ratios) move from projection 🔴 → synth-sim 🟡.
  3. Does the wave preserve all 75 Sacred ROM cells? — ✅ YES; R18 forbids alteration. PDK retargetting touches only synthesis mapping, not the spec layer.
  4. Does the wave introduce an R-marker cell? — NO; R6 N/A.

5. R-rules compliance

  • R-SI-1: zero * in any new RTL/netlist on either PDK
  • R5-HONEST: report.md MUST label 🟡 SYNTH-SIM and disclose Liberty-proxy gap
  • R7: This issue IS the falsification pre-registration. Hypothesis bound to W31-G1..G3.
  • R15 sacred-synth-gate: no new opcode allocated
  • R18 LAYER-FROZEN: no Sacred ROM changes; Lanes V/W/V'/S RTL untouched
