Summary

  • Speed up large-design placement with vectorized generation and batched optimization
  • Keep overlap at 0.0000 with adaptive overlap handling and deterministic legalization
  • Replace quadratic overlap-cell metric check with exact spatial hashing for scalability

Validation

  • Full test suite passes (12/12)
  • Average Overlap: 0.0000
  • Average Wirelength: 0.8736
  • Total Runtime (harness): ~13s
