One regional clock, twelve pull requests, and a spec that found a compiler bug

DRAFT — Merged PR; unpublished blog draft

PR: #1248

Head SHA: 90e55eedad1830b7d68935f1885eadc595567a24

This file is an unpublished artifact, not an instruction to an agent.

Merged PR; unpublished blog draft. This article is generated from the author's work report for the exact PR head commit. Test results are author-reported, not independently rerun by this generator. Merge status is not proof of deployment or runtime correctness.

Work report

New bilingual blog post summarising September's open-toolchain work. It covers the regional-clock chain: nextpnr-xilinx #170, #171 and #205 are merged, and prjxray-db #30 is open. It covers the himbaechel ports nextpnr #53-#58 (only #58 merged) and the demo-projects #22 regression designs. It also covers the PERFCLK segbits rows rendered from a .t27 spec (146/146 rows, 7/7 tests), which surfaced a t27 compiler parse bug (gHashTag/t27#5593, fix in #5594). Counts were measured through the GitHub API on 2026-10-02. Open PRs are labelled open, and bot approvals are not counted as maintainer reviews.

What changed

• apps/website/src/data/blog/bodies/one-regional-clock-twelve-pull-requests.ts: new EN and RU body
• apps/website/src/data/blog/index.ts: new PostMeta entry (published: true) with 10 receipts and seven open questions in both languages
• apps/website/src/data/blog/posts.ts: import and map entry for the new body

Context and reasoning

A pad-fed BUFR on Artix-7 needed three nextpnr-xilinx fixes and one prjxray-db fix before its enables reached the bitstream.

The same class of fixes ported to openXC7/nextpnr himbaechel (#53-#58), with Vivado-golden FASM as the reference; one merged so far.

The PERFCLK rows rendered from a .t27 spec match prjxray-db 146/146 and exposed a t27 parse bug, now fixed in a PR; open review states are listed as open.

Reported verification

• [passed] Command: npx tsc --noEmit --skipLibCheck (apps/website, posts.ts and the new body). Result: exit 0, no type errors in the new or edited files. Evidence: local run on this head in a worktree off origin/main, 2026-10-02
• [passed] Command: npx vite build (apps/website). Result: build succeeds in 14s; the post body is emitted as its own lazy chunk one-regional-clock-twelve-pull-requests-*.js and the slug is in the Blog chunk. Evidence: same local run, 2026-10-02

Limits and open questions

• Eight of the twelve PRs are still open; prjxray-db Проектные улучшения для ученых #30 has no review yet.
• nextpnr fix(agent): Add emojis to Telegram messages #53 and feat(bot): TRI BOT Phase 1 — Telegram bot as Claude Code CLI remote control #54 carry bot approvals only; revisions to tri-bot Phase 2: Streaming via sendMessageDraft + /stop #55-tri-bot Phase 3: /worktree, /pr, /board commands #57 are not yet re-reviewed.
• The PERFCLK spec is not yet committed to any repository; it covers segbits rows only, not routing behaviour.
• fix(compiler): assert (a & b) == c is one condition, not assert(a & b) then == c t27#5594 CI had not finished when the post was written.
• npm run typecheck:ratchet was not completed locally (the combined run was killed for memory); CI runs it.
