Synthesis Metrics Reference

Core metrics for synthesis closure and QoR governance.

Core metric families

  • Timing: WNS, TNS, violating endpoints by path group.

  • Area: cell area, buffer overhead, macro interaction.

  • Power: dynamic, leakage, clock power share.

  • Flow quality: unconstrained count, runtime, reuse ratio.

  • Stability: regression pass rate and correlation drift.
