Abstract

A method and system for timing exception verification in integrated circuit (IC) designs included verification of functional false paths as well as multi-cycle paths (MCPs). A false path or a MCP is modeled to a satisfiability formula and the formula is validated using a Boolean satisfiability solver. Time required for timing exception verification can be significantly reduced.
