A technique to verify, evaluate, and estimate the performance of an integrated circuit is embodied in a computer software program that is executable by a computer system. When simulating performance, scalars for transient performance are determined for strongly couple components. The technique accurately estimates of the performance (e.g., transient delays) of an integrated circuit, and has fast execution times. The technique is applicable to small circuits having relatively few transistors, and especially well suited for integrated circuits having millions of transistors and components. The technique handles the effects of deep-submicron integrated circuit technology.

Method of using strongly coupled components to estimate integrated circuit performance

A technique to verify, evaluate, and estimate the performance of an integrated circuit is embodied in a computer software program that is executable by a computer system. To estimate performance, the integrated circuit design is partitioned into strongly coupled components and state points are identified. The technique accurately estimates of the performance (e.g., transient delays) of an integrated circuit, and has fast execution times. The technique is applicable to small circuits having relatively few transistors, and especially well suited for integrated circuits having millions of transistors and components.

Method of vector generation for estimating performance of integrated circuit designs

A technique to verify, evaluate, and estimate the performance of an integrated circuit is embodied in a computer software program that is executable by a computer system. The technique accurately estimates of the performance (e.g., transient delays) of an integrated circuit, and has fast execution times. The technique includes an incremental recharacterization feature where only portions of the design which have been changed or are new or different will need to be recharacterized during subsequent runs of the software. Portions of the design which are the same need not be recharacterized, and results for those portions from a previous run (stored in a database) are used. This saves execution time since the performance recharacterization or evaluation process is generally more time consuming than a database look up. The technique is applicable to small circuits having relatively few transistors, and especially well suited for integrated circuits having millions of transistors and components. The technique handles the effects of deep-submicron integrated circuit technology.
