Pre-scan reference: TOPS-SCAN-W28-PRE-001 (trinity-fpga#105)
Predecessor: L-DPC24 HOLOGRAPHIC v9 — CLOSED 2026-05-15, 10/10 lanes merged (trinity-fpga#100)


0. R5-HONEST disclaimer

W28 target 150 TOPS/W = gate, not claim. Refuted on TTIHP27a silicon return if measured < 100 TOPS/W. v9 HOLOGRAPHIC 2000-3000 TOPS/W projection remains intact and orthogonal (multi-die scale-out × R-marker compression).


1. Hypothesis H_W28 (pre-registered, R7 falsification gate W28-G1)

H_W28 (Lever Stack #1+#2+#3):
  measured TOPS/W ≥ 100 on TTIHP27a silicon, holo 1×2 boot,
  BitNet b1.58-3B kernel, Vdd=1.2V, ambient 25°C, n=9 dies,
  Welch t-test α=0.01, Bonferroni × 3 lanes (V, W, X).

REFUTED IF (any one):
  - median TOPS/W < 100, OR
  - LUT PE energy/op > 2× ternary shift-add baseline, OR
  - BitROM BER > 1e-9 across 10^12 reads, OR
  - any holo_op variant introduces rtl_uses_star = true, OR
  - 1-cycle NoC scaling 2×2 mesh latency_cycles ≠ 1.

DEADLINE: 2026-09-30 (TTIHP27a silicon return + smoke probe).

2. Three-lane lane map

Lane V — lut-pe-platinum (Platinum-style LUT PE) — TOP priority

  • Source: Platinum ASP-DAC 2026 — arXiv 2511.21910
  • Spec: Ternary LUT (3⁵ = 243 entries with Mirror Consolidation → ⌈243/2⌉ = 122) + MST path-construction offline. Replaces shift-add PE; preserves R-SI-1 (zero * operator).
  • Repo: gHashTag/tt-trinity-holo
  • Files: rtl/holo_lut_pe.sv, rtl/holo_lut_pe_tb.sv, tools/gen_lut_table.py, docs/V_LUT_PE.md
  • Predicted gain: 1.3-1.4× over Wave-15a shift-add
  • Effort: M · R-SI-1 attestation required in PR body

Lane W — bitrom-weight-bank (BitROM bidirectional ROM) — STRATEGIC

  • Source: BitROM ASP-DAC 2026 — arXiv 2509.08542 (Yoshioka lab)
  • Spec: Bidirectional ROM cell storing 2 ternary weights per transistor; replaces SRAM weight bank. Co-designs with 0xDE LOAD_PHYSICS_CONST (Lane C') to make boot truly constant-time.
  • Repo: gHashTag/tt-trinity-holo
  • Files: rtl/holo_bitrom_bank.sv, rtl/holo_bitrom_bank_tb.sv, docs/W_BITROM.md (+ IHP SG13G2 floorplan note)
  • Predicted gain: ~2× TOPS/W (ROM read vs SRAM switching)
  • Effort: L · physical design on SG13G2

Lane X — coq-holo-op-extension — formal proof

  • Spec: Extend t27/trios-coq/IGLA/RMarker.v with Inductive holo_op alphabet covering {LUT_LOOKUP, BITROM_READ, NOC_FORWARD, R_MARKER_LATCH, RAZOR_SAMPLE}. Prove Lemma holo_op_no_star : forall op, rtl_uses_star op = false. Add Definition lever_stack_safe (oplist : list holo_op) : Prop := Forall (fun o => rtl_uses_star o = false) oplist.
  • Repo: gHashTag/t27
  • Files: trios-coq/IGLA/HoloOp.v, append to trios-coq/_CoqProject
  • Predicted gain: L3 (Verifiable compute) lever stays 🟢, makes Trinity the ONLY 5/5 after silicon return
  • Effort: S · zero admit., zero Axiom

Lane V' — noc-2x2-mesh (PARALLEL — Lever #3)


3. Critical path & parallelisation

   Lane X (Coq spec)  ───────┐
                              ├─→ Lane V (LUT PE) ──┐
   Lane W (BitROM bank) ─────┤                       ├──→ TTIHP27a tape-out gate W28-G1
                              └─→ Lane V' (2×2 NoC) ┘

Lane X is the gate: it defines holo_op alphabet that Lanes V, W, V' must conform to.

Parallel-safe after Lane X: V, W, V' (no file overlap).


4. Success criteria (verification matrix)

Gate Predicate Lane
W28-G0 All 4 lanes merge with phi^2 + phi^-2 = 3 CI check green V, W, X, V'
W28-G1 Measured TOPS/W ≥ 100 on TTIHP27a silicon post-silicon
W28-G2 LUT PE energy/op ≤ 2× shift-add Lane V
W28-G3 BitROM BER ≤ 1e-9 over 10^12 reads Lane W
W28-G4 holo_op_no_star theorem Qed (no admit) Lane X
W28-G5 2×2 mesh latency_cycles = 1 in tb Lane V'

5. R-rules compliance

  • R-SI-1: zero * in any new RTL — tools/check_no_star.sh from Lane U gate must pass
  • R5-HONEST: Every lane PR must label measurements 🟢 silicon / 🟡 sim / 🔴 projection
  • R7: This issue IS the falsification pre-registration. Hypothesis bound to W28-G1.
  • R15 sacred-synth-gate: Lane W BitROM mass-bake = LAYER-FROZEN ROM, no firmware write
  • R18 LAYER-FROZEN: TTIHP27a configs explicitly set RUN_KLAYOUT_DRC: true
