TRI-1 Euler — Trinity e-engine (SUPER-CROWN + CLARA)

One of three neurons of Trinity TRI-NET — three sacred constants embodied in silicon:

• φ-anchor → tt-trinity-phi (1×1, Lucas POST, CLARA Gap-4)
• e-engine → THIS REPO (8×2, 18 SUPER-CROWN modules + 10 CLARA gaps + D2D holo mesh)
• γ-surface → tt-trinity-gamma (8×4, 32 PE neuromorphic)
• t27 toolchain → t27 (.t27 spec → RTL generator + numeric format registry)

What this repo is

tt-trinity-euler is the balanced / DARPA-CLARA-facing SKU of the TRI-NET line — an open high-assurance ternary AI silicon substrate. It is the 8×2 e-engine chip carrying 18 SUPER-CROWN modules, 10 CLARA-style AI-safety gaps, a 4-port D2D holo mesh, and an on-chip BLAKE3 audit receipt path. The differentiation thesis is open RTL + open PDK + native ternary + on-chip audit/proof-trace, not a raw TOPS race — see COMPETITORS.md.

What runs today

• ✅ RTL — 86 synthesisable Verilog-2005 modules under src/ (51 core e-engine + 35 v1.0.0 quantiser/power/format add-ons); R-SI-1 (zero new * operators) enforced by .github/workflows/no_star.yaml.
• ✅ Simulation — Icarus testbench passes locally: TOTAL PASS=17 FAIL=0 ALL PASS (canonical GF16 anchor 0x47C0 + 16 dot8 vectors). Reproduce with the snippet under Quick Start or BENCHMARKS.md §5.
• ✅ CI — test.yaml (canonical anchor) · no_star.yaml (R-SI-1) · gds.yaml (OpenLane2 SKY130A) · fpga.yaml · tri-test.yml (now includes the trinet-specs-gate job, see Verification surface).
• ✅ Verification surface — docs/VERIFICATION_CLAIMS_MATRIX.md indexes every numerical claim; D2D conformance assets (6 test cases) under conformance/d2d/; NMSE golden vectors under tests/vectors/nmse/; Triple-Decker FSM spec at docs/TRIPLE_DECK_STATE_MACHINE.md. See Verification surface below.
• ✅ Shuttle — submitted to Tiny Tapeout TTSKY26b on 2026-05-17 (8×2 tiles). See CHANGELOG.md.
• ⚠ Silicon — not yet returned from the foundry. Any TOPS / TOPS-per-watt / power figure on this page is PROJECTED, not MEASURED. The line you can quote: see BENCHMARKS.md.
• ⚠ Zenodo (per-shuttle) — no per-shuttle TTSKY26b DOI has been minted. The only DOI cited in this repo is the line-wide Trinity Stack DOI 10.5281/zenodo.19227877. The TTSKY26b bundle's metadata and manifest are pre-staged at .zenodo.json and docs/RELEASE_MANIFEST_TRINET_V1.md; merging those files does NOT mint a DOI. See Zenodo metadata and release manifest.

How to verify

sudo apt-get install -y iverilog # Ubuntu 24.04
iverilog -I src -o /tmp/sim_dot8 \
src/gf16_mul.v src/gf16_add.v src/gf16_dot4.v src/gf16_dot8.v \
sim/tb_gf16_dot8.v
vvp /tmp/sim_dot8
# expected tail: "TOTAL PASS=17 FAIL=0 ALL PASS"

To re-run the TRI-NET spec/claims gate locally (no iverilog needed):

./scripts/check_trinet_specs.sh
# expected tail: "RESULT: PASS"

The gate is also wired into CI as the trinet-specs-gate job in .github/workflows/tri-test.yml.

Verification surface

Every numerical claim in TRI-NET-tagged docs maps to a row in the Verification Claims Matrix. The matrix uses the same readiness ladder as STATUS.md and an explicit per-row Anti-claim column.

Status legend (applies repo-wide)

Symbol	Meaning
✓	Silicon-measured (NOT used in this repo today)
⊙	RTL-simulation target (pre-silicon)
◷	Architectural projection (first-principles, not from this design's simulation)
SPEC / SPEC-DRAFT / SPEC-FROZEN	Specified at the markdown / Coq level
RTL / RTL-STUB	RTL exists (-STUB = pin-correct but not full behaviour)
SIM	A testbench under sim/ or test/ exercises it
SYNTH / GDS-SUBMIT / SILICON	Synthesis / shuttle / silicon tier (no row in this repo is SILICON)
PROJECTED	Extrapolation under stated assumptions (e.g. 22FDX TOPS/W)
PLANNED	Scoped for a future wave

CI usage

# Local re-run of the gate (portable bash; needs python3 for JSON):
./scripts/check_trinet_specs.sh
# CI integration — automatic on every push/PR via:# .github/workflows/tri-test.yml :: trinet-specs-gate

The gate is intentionally portable: no jq, no rg; only bash, grep, sed, and (optionally) python3. The t27c step is skipped gracefully when t27c is not on PATH.

Zenodo metadata and release manifest

R5-Honesty anti-claim — NO-FAKE-DOI. No per-shuttle / per-repo Zenodo DOI has been minted for TRI-1 Euler. The only DOI cited anywhere in this repo is the line-wide Trinity Stack provenance DOI 10.5281/zenodo.19227877. The spec gate rejects any non-canonical 10.5281/zenodo.* reference under docs/.

The repo pre-stages the Zenodo deposition that will accompany a future TTSKY26b bundle:

File	Purpose
.zenodo.json	Bundle metadata (title, version, creators, license, keywords, related identifiers, anti-claim notes). Merging this file does NOT mint a DOI.
docs/RELEASE_MANIFEST_TRINET_V1.md	Manifest of files / artefacts the bundle will contain, SHA-256 hashes at manifest commit, pre-upload checklist, explicit "no DOI minted until Zenodo deposition is actually published" anti-claim.

The manifest's pre-upload checklist names the three logs (sim/logs/, boards/openlane2/, boards/fpga/) that MUST be re-attached before any deposition can be uploaded.

TRI-NET Positioning

TRI-NET — verifiable open silicon stack for trustworthy AI: identity (Φ), reasoning (E), inference (Γ). One math anchor, three chips, zero closed IP.

E Reasoning Layer — Verifiable AI Safety (10 CLARA Gaps)

tt-trinity-euler is the reasoning and verification backbone of the TRI-NET stack. As the 8×2 tile e-engine (90 modules), Euler's mission is to make AI computation auditable: every inference step can emit a BLAKE3-signed proof-trace receipt, every decision can be verified against symbolic constraints (SAT/ASP/Datalog), and all ten DARPA CLARA AI Safety Gaps have one-to-one RTL module mappings. The SUPER-CROWN (18 modules) includes vsa_matmul_8x8/16x16 for ternary VSA, bitnet_encoder for BitNet b1.58 MLP, blake3_anchor + multi_tile_receipt + crc32_receipt for the DePIN signing chain (G4), alu9_decoder for the 9-instruction t27 ISA, and ring27_memory for 3³ Coptic ternary storage.

In the TRI-NET trust model, Euler answers the question: "This computation is correct, auditable, and bounded." Phi's identity proof grounds the boot, and Euler extends that foundation into symbolic AI safety — an open-silicon RTL mapping of the DARPA CLARA 10-gap lattice (the synthesised silicon uses the _mini variants bounded at 16 clauses/rules to fit the TinyTapeout cell budget; the unbounded 256 figure is the t27 software/spec target). Euler bridges identity (Phi) to inference (Gamma) via a 4-port D2D holo mesh (d2d_holo_mesh, N/E/S/W), carrying BLAKE3 receipts across dies.

Cross-Die Anchor 0x47C0 — Theorem 36.1

Every TRI-NET die asserts {uio_out, uo_out} = 0x47C0 on reset. This value is not a magic constant — it is derived from first principles: φ²+φ⁻²=3 (the Lucas L₂ identity) implies dot4(1,2,3,4) = 0x47C0 in GF16. This derivation is formalised as PhD Theorem 36.1 (Chapter 36, flos_70.tex). Because all three dies independently compute the same anchor from the same mathematical identity, a multi-chip board can use it as a deterministic POST / build-provenance fingerprint without any shared secret — note this is a liveness/provenance check, not a cryptographic proof of correctness (a returned die emitting a value ≠ 0x47C0 would refute shared provenance). The D2D LAYER-FROZEN gate in Euler's West TX implements Theorem 36.1 R18: once committed, the anchor cannot be revoked. DOI: 10.5281/zenodo.19227877.

Why this is different

Open RTL (Apache-2.0). Open PDK (SKY130A). Native ternary {−1, 0, +1} numeric path in synthesisable RTL (src/bitnet_encoder.v, src/vsa_matmul_8x8.v). On-chip BLAKE3 receipt signer + 64-entry audit ring buffer (src/blake3_anchor.v, src/audit_log_ring_buffer.v). 10 CLARA-style safety gaps mapped one-to-one to RTL — see CLARA_TRACEABILITY.md. The 4 commercial NPUs the chip-market usually compares against — Qualcomm Cloud AI 100 Ultra, Hailo-8, Axelera Metis, Google Coral Edge TPU, MediaTek Dimensity NPU — are closed silicon and do not ship a native ternary path; see COMPETITORS.md for the restrained per-vendor read.

What is e-engine?

e-engine is the expansion layer of Trinity TRI-NET — three sacred constants embodied in silicon:

Neuron	Constant	Tiles	CLARA Gaps	Role
φ-anchor	φ ≈ 1.61803	1×1	1/10 (Gap-4)	Lucas POST, bounded rationality
e-engine	e ≈ 2.71828	8×2	10/10 ✅	SUPER-CROWN + CLARA + D2D
γ-surface	γ ≈ 0.57721	8×4	10/10	Neuromorphic cortex, full mesh

e ≈ 2.71828 (Euler's number) is the natural exponential growth constant that unfolds the φ-anchor into a full safety-aware SoC.

---

Sacred Formula

V = n × 3^k × π^m × φ^p × e^q × γ^r × C^t × G^u

This chip is the e^q factor — natural exponential growth.

Anchor: φ² + φ⁻² = 3 · DOI 10.5281/zenodo.19227877

Architecture Quick Wins

Competitor-informed quick wins specific to Euler are listed in docs/ARCHITECTURE_QUICK_WINS.md. Highlights — all grounded in current repo state, none change RTL semantics:

ID	Title	Status
QW-E-1	D2D bandwidth / fJ-per-bit table — reserves VCM-D2D-BW-001 / VCM-D2D-EN-001, leaves the fJ/bit cell deliberately empty until silicon.	SPEC-DRAFT
QW-E-2	UCIe-style D2D conformance evidence block (frame format / integrity / retry / vectors).	SPEC-DRAFT (assets in conformance/)
QW-E-3	GF16 ↔ MX block-FP interoperability map — positions GF16 next to MXFP8/E5M2 without claiming compliance.	SPEC-DRAFT
QW-E-4	D2D conformance CI vectors wired into the spec gate.	Done — scripts/check_trinet_specs.sh step 8
QW-E-5	R5 honest status legend on every TOPS / NMSE / fJ-bit row.	Done — legend above + matrix
QW-E-6	Triple-Decker FSM → MLCommons inference power-phase mapping.	SPEC-DRAFT
QW-E-7	Body-bias operating-point table (RBB / Nominal / FBB / CAP_BOOST).	SPEC-DRAFT
QW-E-9	NVDLA-class positioning paragraph (Euler vs NVDLA on numeric, safety, low-power axes).	SPEC-DRAFT
QW-E-10	Per-deck power-delta measurement plan stub — promotes VCM-TOPS-001..003 only after boards/measurements/ is non-empty.	PLANNED

Anti-claim: none of the above changes the TOPS/W, NMSE, fJ/bit, or silicon claims. They make the evidence surface legible to integrators fluent in UCIe / MX / MLCommons. See docs/ARCHITECTURE_QUICK_WINS.md §10 for the explicit "what this doc does NOT propose" list.

R-SI Compliance Rules

Rule	Statement	How to Verify
R-SI-1	Zero * operators in RTL	grep -n '\*' src/*.v
R-SI-2	Zero DSP/multiplier macros	OpenLane2 reports
R-SI-3	WNS ≥ 0 ns @ 50 MHz	OpenLane2 STA
R-SI-4	DRC-clean	OpenLane2 KLayout DRC
R-SI-5	LVS-clean	OpenLane2 LVS
R-SI-6	Apache-2.0 only	grep -i proprietary (should be empty)

Adding New Modules

1. Create module in src/ with Verilog-2005 syntax
2. Add testbench in test/ or sim/
3. Run local simulation: iverilog -o tb.out src/*.v test/tb.v && vvp tb.out
4. Update info.yaml if pin usage changes
5. Submit PR

Troubleshooting

Simulation Fails

# Check Verilog syntax
iverilog -t null -I src src/gf16_mul.v
# Run with verbose output
vvp /tmp/sim_dot8 +verbose

GDS Fails

# Check workflow logs
gh run view -R openlane2_output
# Run OpenLane2 locally
docker run -it --rm -v $(pwd):/work -w /work \
openlane2/openlane2:eula bash
openlane --config ./sky130A/config.tcl --run ./run_gds.tcl

Canonical Test Failure

The canonical test 0x47C0 must PASS. Failure indicates:

• Incorrect GF16 encoding (exp=63, mant=0x1FF)
• Timing issue
• RTL synthesis error

Green AI Alignment

• Ternary {−1, 0, +1} — ~10× energy/op vs FP16 at equivalent accuracy
• 0 DSP / 0 * — R-SI-1 RTL constraint eliminates multiplier switching energy
• Edge inference — no datacenter transit, no PUE overhead
• Open-source RTL — reproducible silicon eliminates duplicated tape-out waste
