Abstract

In this paper, the initialization of sequential circuits using pseudorandom input patterns is addressed. An extended Markov chain model that covers the initialization phase is proposed. This model support the theoretical framework used to demonstrate that sequential circuits can be initialized with pseudorandom vectors. This leads to a uniform BIST approach in which initialization and testing are performed together with a single pseudorandom generator.
