Abstract

A new algorithm, O-algorithm, for automatic test program generation of microprocessors in a user environment is presented. Specifically, to eliminate the redundant tests, a weighted-digraph model is used to model the signal flow of the general microprocessors. Improved functional fault models of microprocessors are derived from Turing machine model. The O-algorithm is then constructed based on the signal flow model and functional fault models. The complexity of our algorithm is better than [6]. Moreover, the simulation had shown that the fault coverage is better than 97%.
