Abstract

Timing verification of VLSI designs using statistical techniques such as those implemented in Hitchcock's Timing Analysis1 permit a far more precise assessment of machine performance than previous techniques. The accuracy of these results is affected by proper user specification of statistical input parameters and by the algorithmic treatment of the system design. Since these items are both system and technology dependent, the system designer must understand them and apply appropriate statistical techniques in order to insure a properly verified design. This paper both outlines the mathematical derivations and illustrates the magnitude of the improvements to be obtained.
