Patent ID: 8239796

Claim:
A computer system for automatically synthesizing relative timing (RT) constraints for facilitating timing verifications of an integrated circuit design, said computer system comprising: means for receiving a plurality of trace status tables containing a plurality of trace errors identified by a formal verification engine that performed an RT verification on an integrated circuit design; means for identifying an error causing signal for each of said trace errors; for each of error causing signals, means for determining two associating signals; means for utilizing said two associating signals to locate a common point of convergence (POC); means for backtracking said POC to locate a common point of divergence (POD); and means for generating an RT constraint based on said POC and POD; and means for inserting an RT constraint for each of said trace errors within said integrated circuit design, wherein said RT constraints specify the relative ordering of arrivals of signals in order to avoid any timing violations such that said integrated circuit design is able to pass said RT verification in the future.
