Do NOT merge. Temporary PR to drive a cloud build with:

  • upcounter switched from ihp_sg13g2 + blockgf180mcu + pga144
  • [chipflow.backend.check.drc] enable = true so drc_klayout actually runs

Goal: verify chipflow-backend PR #323 (gf180mcu edi2gds layermap install + drc_klayout / lvs_klayout gating refactor) end-to-end on a real cloud build.

What this exercises:

  • def2stream writes routing to the proper GDS layers (Metal2 → 36/0, vias → 35/0/38/0/40/0, …) instead of internal indices (5/0, 3/0, …)
  • klayout:lvs produces "extracted netlist fully match output verilog file"
  • klayout:drc:gf180mcu and klayout:drc:gf180mcu_antenna complete and ship .lyrdb reports

Revert before merging — this PR is for triggering CI only.

Exercises the gf180mcu LVS layermap fix and the drc_klayout plugin
end-to-end in cloud build, using PR #323's merged backend.

Do NOT merge — revert before any merge to main.
