Abstract

For verifying complex sequen tialbloc ks such as microprocessor embedded arrays, the formal method of symbolic trajectory ev aluation (STE) has achieved great success in the past [[3], [5], [6]]. P ast STE methodology for arrays requires manual creation of “assertions” to which both the RTL view and the actual design should be equivalent. In this paper, w e describe a novel method to automate the assertion creation process which improves the efficiency and the quality of array verification. Encouraging results on recent P owerPC arrays will be presented.
