Abstract

In the timing analysis of a system, it is often necessary to evaluate the path delays involved in the system when changes occur to an already characterized system. Currently, this requires that a calculation be performed for every block in a graph, where the "blocks" correspond to various portions of the system. To reduce the test time, it is proposed to test only the activated or changed conditions such that calculations are performed only on those blocks which actually change, rather than performing calculations on the entire system.
