Abstract :
In this paper we present a new approach to fault diagnosis in sequential circuits based on an effect–cause analysis. This represents an extension of our previous work dealing with combinational circuits [1]. The main tool of our approach is the Deduction Algorithm, which deduces internal values in the circuit under test based upon the test results. The deduced values are used for fault diagnosis, which encompasses both fault detection and location.
