Silicon Validation Policy (P5B)

Scope

• Block and top level only.

Mandatory Checks

• Constraints quality and syntax validation
• Synthesis PASS on block/top
• CDC/timing signoff checklist pass
• Top integration precision regression PASS
• Equivalence validation when synthesis-significant optimization or ECO/refactor delta exists

Conditional Expert Delegation (P5B)

• Invoke equivalence-checker when either condition is true:
  • Gate/netlist generated from updated constraints/synthesis flow must be proven equivalent to RTL
  • "Behavior-preserving" RTL ECO/refactor enters P5B signoff path
• Equivalence scope:
  • RTL-vs-netlist for synthesis outputs
  • RTL-vs-RTL for ECO/refactor delta verification
• Equivalence FAIL/UNKNOWN is signoff-blocking unless explicitly waived by user/design owner.

Hard Gate

• P5A functional closure must be PASS before P5B can pass.
