Abstract

A system for allowing a user to assign timing specifications to points in a circuit and have the timing properties of the circuit analyzed with respect to the timing specifications. The system allows timing specifications such as maximum propagation delay, clock-to-output delay, setup time and maximum clock frequency to be assigned at any point in the circuit. The system uses predefined rules to determine which of multiple possible specifications are to be used in analyzing each path of the circuit. A method of concurrently performing the assignment and analysis is described.
