Severity: major

Justification: Range bumps yosys 0.62 → 0.63 → 0.64 (via BCR custom registry, with abc lockstep enforcement), and walks ORFS / OpenROAD through several tips (now ORFS a8b85cd6 / OpenROAD 5e0c6404 via archive_override + submodule patch_cmds). Adds many new public APIs (orfs_run_executable, orfs_blender 3D viewer, lib_to_verilog, compute_floorplan_shape, compute_slack_margin, memory_macro_scaler, kept_macros per-partition macro scoping, local_arguments, user_sources, yosys_plugins). New power.bzl Verilator-SAIF → OpenSTA report-power pipeline. New openroad_qt subsystem that routes bazelisk run gui_<stage> through the Qt binary (with the openroad-10384 patch splitting src/gui:gui_stub). All of these are infrastructure-affecting for HighTide's RTL-to-GDS flow and could trigger broad re-synth / re-floor.

What changed (highlights)

• Tool bumps
  • yosys 0.62.bcr.2 → 0.63 (32846d0), then BCR-sourced via ORFS tools/yosys YOSYS_VER (3c2cc26); then yosys 0.64 via custom registry (BCR PR #8862, 6ebadeb); abc lockstep enforced (dfdc1c4, softened in 04e0009)
  • ORFS walked through 87b01b74 → 2f6e9c9b → 74b5f961 → b23706a6 → a8b85cd6; OpenROAD through 8546cd02 → 08f67ee5 → 5e0c6404
  • OpenROAD now pinned via archive_override + submodule patch_cmds (40759ce); submodule tarballs staged in repo workdir, not /tmp (d18bf13)
  • yosys-slang sourced from ORFS tools/ submodules (76b8531)
• openroad_qt subsystem (new)
  • openroad_qt: use @openroad//:openroad-qt for bazelisk run gui_<stage> (19572e6); route bazelisk run wrappers through Qt binary (bb63631); scope to interactive stage wrappers only (21dc075)
  • openroad-10384 patch: split src/gui:gui_stub from :gui (7c5fa06)
  • Gallery bumped openroad to match //MODULE.bazel + apply openroad-qt patch (87ba908)
• New public APIs
  • orfs_run_executable for bazelisk-run TCL targets (4511a20)
  • orfs_blender() + orfs_flow(blender=True) — 3D viewer for final-stage GDS (67f4cc5, dd6074a); blender_supports_pdk predicate (b3b19b0)
  • orfs_gds declares 6_final.def, fixes klayout under sandbox, honors klayout attr (e8ede25)
  • compute_floorplan_shape + compute_slack_margin scripts (df03cc3)
  • lib_to_verilog emits behavioral Verilog for stdcells from .lib (5695d8d)
  • memory_macro_scaler emits per-bit pins in .lib bus blocks and .lef (9b3270c)
  • kept_macros API for per-partition macro scoping (e5aa446, 8d930b8, 6b67e07)
  • archive_override for ORFS pin (3e1dc5e)
  • local_arguments to drop helper vars; explicit config.mk (a816102, 7bccbf0); user_sources= design-private path hooks (c000cb3)
  • orfs_design.default() exposes yosys_plugins attribute (f884756)
• Build / infra
  • gnumake: drop zig bootstrap, build with cc_binary (943cae5); hzeller PR #717 review (8e8ade8); document --override_repository host-make escape hatch (05bbceb)
  • power.bzl: Verilator-SAIF → OpenSTA report_power pipeline (e944956)
  • synth_partition.sh: fix SYNTH_SKIP_KEEP truthy check; non-greedy kept_modules.json parse; JSON parser pinned against slang [N] names
  • bump: tooling improvements — fail loudly on unexpected MODULE.bazel; --ignore; refresh MODULE.bazel.lock; soften yosys/abc lockstep; remove stale 0.63/0.65; skip in-comment matches in override-block finders (a1dc1c4)
  • render_gds: trim layerstack before Blender import (3a5ddd7); monkey-patch PDK_CONFIGS instead of gdsii_use_custom_config (bfd3a1d)
  • yosys: pass use_pre_layout=True when writing 1_synth.short.mk (641150d)
  • submodules: apply patches 0036/0037 to @orfs+ from sub-workspaces (964d545); patch 0037 later dropped (a6d7dc1); patch 0035 dropped — upstream ORFS now gates overrides with dev_dependency=True (0184aa0)
  • Deprecated integration sub-workspace deleted (8be8907); unwired test/spelling_error sub-workspace deleted (1963859)
• CI / lint
  • Drop --@openroad//:platform=gui to stop double-building openroad (fd18fe2)
  • Bust external-openroad+ cache after src/sta submodule restructure (2631171)
  • fix_lint cleanups + black/buildifier
  • test/downstream: disable lockfile generation (59a736e)
• Determinism helpers
  • yosys-check + make-yosys-netlist OpenROAD determinism helpers (15be95f); TESTING.md documentation (ce6efd9); make-yosys-netlist clears VERILOG_FILES on re-synth (dcaad31)

Recommendation

Update with caution + plan rebase work — yosys 0.62 → 0.64 and the OpenROAD bump will trigger a full re-baseline across every HighTide design. New APIs (kept_macros, local_arguments, user_sources) may let HighTide simplify several existing workarounds (e.g. the per-design helper-var passthroughs). Verify all arguments = { ... } env-var workarounds in the bug table still apply post-bump. The render_gds / orfs_blender additions may complement or replace HighTide's own _gallery rendering — worth reviewing. The new openroad_qt GUI wrappers won't affect headless cache builds but may simplify local debugging.
