Formal Verification (FPV) for RTL, IP & SoC

Complete FPV execution from spec to signoff:

• Requirement and micro-architecture analysis

• Property specification and verification planning

• Assertion development (SVA / PSL)

• Proof execution and convergence

• Coverage, completeness, and closure metrics

• Signoff reporting with full traceability

Formal verification explores all possible states of your design — mathematically.

• No test vectors required

• No random stimulus dependency

• No coverage blind spots

• No missed corner cases

Reduce risks of silicon escapes

Properties are mathematically proven to be always true — across all possible input combinations. This dramatically reduces the risk of silicon escapes.
