Predecessor: L-DPC26 Wave-29 — CLOSED 2026-05-15, W29-G0 ✅ (trinity-fpga#108)

0. R5-HONEST disclaimer

Wave-30 = timing-closure probe wave, not a tape-out wave. All numbers from sim/synthesis. 400 MHz target on TTIHP27a is a gate, not a claim. Refuted by synthesis if slack < 0 ps at 400 MHz on any Lane V/W/V'/S RTL surface.


1. Hypothesis H_W30 (pre-registered, R7 falsification gate)

H_W30 (Lever #5 — 400 MHz clock push):
  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) achieve positive setup slack
  at 400 MHz clock target on TTIHP27a PDK timing constraints.

REFUTED IF (any one):
  - any of the 4 surfaces has setup slack < 0 ps at 400 MHz, OR
  - any of the 4 surfaces has hold slack < 0 ps at 400 MHz, OR
  - any clock-domain crossing has metastability MTBF < 100 years, OR
  - any RTL surface introduces * operator to meet timing.

DEADLINE: 2026-06-30 (pre-silicon synthesis verdict); silicon gate 2026-09-30.

2. Two-lane lane map

Lane T — timing-probe-400mhz — PRIMARY

  • Spec: Synthesise the 4 RTL surfaces (Lane V/W/V'/S) under TTIHP27a Liberty + SDC at CLOCK_PERIOD = 2.5 ns (400 MHz). Emit per-surface setup/hold slack table. R-SI-1 attestation against post-synth netlist.
  • Repo: gHashTag/tt-trinity-holo
  • Files: sim/timing_probe_400mhz/Makefile, sim/timing_probe_400mhz/constraints.sdc, sim/timing_probe_400mhz/report.md, docs/lever-stack/lane-t.md
  • Effort: S · R5-HONEST: report.md labels 🟡 SYNTH-SIM

Lane K — coq-timing-witness — formal proof

  • Spec: Add trios-coq/IGLA/Timing400.v to gHashTag/t27 with Definition timing_400mhz_safe : Prop := ... over the merged oplist. Proves that adding a clock-period constraint does not introduce any non-* violations. Zero admit.
  • Repo: gHashTag/t27
  • Files: trios-coq/IGLA/Timing400.v + _CoqProject update + NOW.md entry
  • Effort: S

3. Success criteria (verification matrix)

Gate Predicate Lane
W30-G0 Both lanes merge with thermal-gate + L1 TRACEABILITY + GitGuardian green T, K
W30-G1 Lane V positive setup slack @ 400 MHz Lane T
W30-G2 Lane W positive setup slack @ 400 MHz Lane T
W30-G3 Lane V' positive setup slack @ 400 MHz (mesh hop budget) Lane T
W30-G4 Lane S positive setup slack @ 400 MHz Lane T
W30-G5 timing_400mhz_safe Qed (no admit) Lane K

4. Quantum Brain Wave Question

  1. Which 1:1 mapping does this wave add? — PHYS→SI (clock period is a physical constant; 2.5 ns ties directly to TTIHP27a process timing parameters)
  2. Which conjectured constants move toward measured? — Setup/hold slack at 400 MHz on TTIHP27a moves from projection 🔴 → synth-sim 🟡 (silicon-verified 🟢 still ⏳ 2026-09-30)
  3. Does the wave preserve all 75 Sacred ROM cells? — ✅ YES, no new opcodes; constraint-only addition
  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 (no RTL changes expected — constraint-only)
  • R5-HONEST: synthesis report labels 🟡 SYNTH-SIM
  • R7: This issue IS the falsification pre-registration. Hypothesis bound to W30-G1..G4.
  • R15 sacred-synth-gate: No new opcode allocated.
  • R18 LAYER-FROZEN: Sacred ROM untouched; Lanes V/W/V'/S RTL unmodified.
