The Study of Testing Generation Method for Mixed-Signal Circuits

Test generation method for mixed-signal circuits is the key and the difficulty of the study of mixed-signal circuits. Most research is to the analog part, or takes the analog part and digital part as independent circuits. In this paper, the mixed-signal circuit is considered as an entity, we analyses the constraint of analog part and digital part, clarify the principle of activating and propagating the fault in mixed-signal circuit, propose a new Boolean Satisfiability with constraint. In the end, through simulation of examples, the results show the efficiency of the method.
