Summary

  • add an opt-in macro_rtl2gds flow with a dedicated macroPlacement step
  • wire DreamPlace macro-only execution and selective snapshot writeback
  • preserve the default rtl2gds flow and normal placement/legalization behavior
  • update submodule pointers to the feature branches

Dependencies

Validation

  • focused macro-placement and flow tests: 114 passed, 10 skipped, 1 xfailed
  • Ruff and git diff --check passed
  • native skips are due to the current GLIBC ABI mismatch

Unrelated large untracked directories were excluded.
