This book is an extension of one author's doctoral thesis on the false path problem. The work was begun with the idea of systematizing the various solutions to the false path problem that had been proposed in the literature, with a view to determining the computational expense of each versus the gain in accuracy. However, it became clear that some of the proposed approaches in the literature were wrong in that they under- estimated the critical delay of some circuits under reasonable conditions. Further, some other approaches were vague and so of questionable accu- racy. The focus of the...
