Constructing test sequences for hardware designs with parallel starting operations using implicit FSM models

The paper concerns functional testing of hardware models using finite state machines (FSM). Test construction is done by traversing FSM state graph. In this paper we propose a technique for irredundant description of FSM models of parallel-pipeline designs. The technique allows to implicitly specify complex compositional FSM models and to automate construction of test sequences by composing several parallel operations into multi-stimuli.
