From d4050467d631437bbb3e2238a5d5496d3e8f0e2a Mon Sep 17 00:00:00 2001 From: Marcos Date: Wed, 6 May 2026 01:19:54 -0300 Subject: [PATCH 1/3] feat(hw): bootstrap kicad/innerjib7ea-rev-a/ as KiCad 8 project skeleton MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lands the KiCad 8 project envelope for the rev-A InnerJib7EA (POPC_16A) FPGA validation board — empty-but-valid so KiCad 8 opens it cleanly and the kicad-erc-drc CI job reports zero violations against an empty design (the issue #5 acceptance gate). Closes popsolutions/Stays#5. ## Files - kicad/innerjib7ea-rev-a/innerjib7ea.kicad_pro Project envelope (JSON, KiCad 8 schema). Default net class, standard ERC/DRC severities, root sheet UUID matching the empty schematic. - kicad/innerjib7ea-rev-a/innerjib7ea.kicad_sch Empty root schematic (sexpr, version 20231120 / KiCad 8.0 format). No symbols, no nets — pure scaffold for issue #6 (schematic capture) to fill. - kicad/innerjib7ea-rev-a/innerjib7ea.kicad_pcb Empty board (sexpr, version 20240108 / KiCad 8.0). 2-layer copper plus the canonical KiCad 8 user-layer enumeration, net 0 declared per spec, default plot params. No copper, zones, footprints, or tracks — DRC reports clean. - kicad/innerjib7ea-rev-a/fp-lib-table (version 7, no entries) - kicad/innerjib7ea-rev-a/sym-lib-table (version 7, no entries) Empty per-project library tables. Library-isolated by design so contributors don't depend on each other's global KiCad config — every footprint/symbol used by this project must be added explicitly to these tables in subsequent PRs. ## Authoring path kicad-cli is not available on the contributor workstation (Manjaro Linux, KiCad 10.0.1-2 in extra repo, not installed — sandboxed sudo can't install during this session). Files were authored by hand against the published KiCad 8 file-format spec (sexpr-pcb / sexpr-schematic / sexpr-fp-lib-table / sexpr-sym-lib-table at https://dev-docs.kicad.org/en/file-formats/), which the issue body's tooling-prerequisite comment explicitly permits as a fallback. The kicad-erc-drc CI job is the round-trip authority: it installs Ubuntu's kicad on the runner and runs kicad-cli sch erc --exit-code-violations innerjib7ea.kicad_sch kicad-cli pcb drc --exit-code-violations innerjib7ea.kicad_pcb If either rejects the file or reports a violation, the PR fails and is amended. CI is currently the only end-to-end validation available for these files in this session. ## .gitignore Adds two KiCad 8 backup-subsystem rules per the issue body's list: - *-backups/ (KiCad 8 zip-snapshot directories) - _autosave-* (KiCad 8 crash-recovery files) The other items from the user's list (*.lck, *-cache.lib, fp-info-cache) were already present. ## README Flips the rev-a/README.md Status section from "Skeleton. KiCad project files not yet committed" to "Skeleton landed", and marks roadmap item #1 (KiCad project skeleton) as ✅ done with a note on the hand-authored / CI-validated path. ## Out of scope Per issue #5: this PR is the skeleton only. Schematic capture, DDR3 routing, inter-card connector, layer stackup, layout, gerbers — issues #6 onward. ## License KiCad design files are licensed CERN-OHL-S v2 per the repo LICENSE; documentation is CC-BY-SA-4.0 (SPDX header on the markdown). The KiCad sexpr/JSON formats do not have a stable embedded-comment convention for SPDX, so the per-file licence identification falls to this commit message and the directory README.

Ubuntu 24.04's default apt repos (KiCad 7.0.11), which lacks `kicad-cli sch erc` and `kicad-cli pcb drc` (both added in KiCad 8.0). The previous PR in this branch (kicad/innerjib7ea-rev-a/ skeleton) tripped this: KiCad 7's `kicad-cli sch` only has the `export` subcommand and rejects `erc` with "Maximum number of positional arguments exceeded". Switches the install step to add the official KiCad project PPA (`ppa:kicad/kicad-8.0-releases`, https://launchpad.net/~kicad/+archive/ubuntu/kicad-8.0-releases) before `apt-get install kicad`, which pulls KiCad 8.0.x and resolves both the ERC and DRC subcommands the downstream steps already invoke. Also fixes a latent format issue: the rev-A KiCad files declare KiCad 8 sexpr versions (20231120 schematic / 20240108 board) which KiCad 7 cannot parse even if its CLI did support `erc`/`drc`. In-scope for the kicad-rev-a-bootstrap PR because the CI workflow bug directly blocks the issue #5 acceptance criterion ("CI job kicad-erc-drc is green on the PR"). Without this fix the acceptance gate is unreachable for any KiCad 8 project file in the repo. SPDX-License-Identifier: CC-BY-SA-4.0 Authored by Agent 2 (FPGA Hardware).

KiCad 8.0.9 DRC (now correctly running on CI after the PPA fix) rejects this with: [invalid_outline]: Board has malformed outline (no edges found on Edge.Cuts layer) Adds four (gr_line) segments forming a deliberately-non-final 100 mm x 100 mm square outline anchored at (0,0). The real mini-ITX 170 mm x 170 mm envelope (per ADR-001 amendment + rev-a/README) replaces this placeholder in roadmap item #6 (Layout pass) once the layer stackup is locked. 100 mm was chosen instead of 170 mm so reviewers don't mistake the placeholder for the real mechanical envelope on a quick 3D-view glance — anything that small is obviously a "shut DRC up" outline, not a mini-ITX board.
