App.F — Bitstream Archive (Reproducibility Manifest)

Issue: #429 · Target: ~300w · Status: v3.0 draft · Anchor: φ² + φ⁻² = 3

F.1 Scope

This appendix manifests the three bitstreams produced by the openXC7 flow (yosys + nextpnr-xilinx + prjxray, Docker, no Vivado) for the QMTech XC7A100T-1FGG676C (Xilinx Artix-7, 101k LUT, 240 DSP — 0 used). Each artefact is reproducible from the source trees referenced in Ch.28 and bench-measured per Ch.34.

F.2 Manifest

File	Top module	LUT util	BRAM util	Fmax (MHz)	Throughput	Power (W)	SHA-256
`uart_bridge_j2.bit`	`uart_bridge_top`	5.8 % (5,847 / 101,440)	9.8 %	100	115,200 baud	0.94	`<TBD-on-Zenodo-mint>`
`hslm_full_top.bit`	`hslm_full_top`	19.6 % (19,882 / 101,440)	52 %	92	63 toks/sec	1.07	`<TBD-on-Zenodo-mint>`
`vsa_coprocessor.bit`	`vsa_coproc_top`	8.4 %	14 %	105	8 ops/clk	0.98	`<TBD-on-Zenodo-mint>`

SHA-256 hashes are minted at the moment of Zenodo deposition under B002 (FPGA Zero-DSP Architecture). The pre-mint placeholder is intentional — re-running the openXC7 container on a clean checkout produces a byte-identical .bit only when the container digest, source SHA, and seed are all pinned (see Dockerfile.openxc7@sha256:<pin> in repo gHashTag/trios-fpga).

F.3 Cross-references

Ch.28 (issue #422) — synthesis flow, JTAG (Xilinx Platform Cable USB II clone, VID 0x03fd PID 0x0013→0x0008 via fxload, 500 KB/s), UART J2 pin 5/6 = D26/E26, FT232RL @ 115200 baud, protocol v6 (0xAA + 1B len + CRC-16/CCITT), BLK-001 RESOLVED 2026-03-14 (flash_no_sudo.sh macOS-ARM).
Ch.34 (issue #428) — energy budget 0.94–1.07 W bench, ratio ~3,000× vs H100 cluster slot (preliminary, B=1, peer-review pending); conservative chip-level 471×.
App.H (issue #430) — full 13-DOI Zenodo registry; B001-B007 hardware bundles co-locate sources, Verilog, constraint files, and bench logs.
App.I (issue #431) — XDC pin map (J2 connector → bank 14/34 mapping, IOSTANDARD LVCMOS33).

F.4 Reproduction recipe

git clone https://github.com/gHashTag/trios-fpga
cd trios-fpga && git checkout v3.0-PhD
docker run --rm -v "$PWD:/work" \
  ghcr.io/openxc7/openxc7:2026-q1@sha256:<pin> \
  make -C /work hslm_full_top.bit SEED=1597
sha256sum build/hslm_full_top.bit  # expect: <TBD post-mint>

Sealed seed F₁₇=1597 (sanctioned per Ch.13 #395 STROBE).

F.5 Negative space

We deliberately publish no Vivado-licensed artefacts and no encrypted IP. Toolchain is 100 % open-source, mirroring the L1 NO .sh files posture for trainer code (Rust/TS only) by analogy: bitstream provenance is auditable end-to-end.
