Abstract

A high-level test synthesis methodology based onBIST is proposed. This methodology targets the conditionalif-then-else statements in a behavioral descriptionbecause such statements can introduce testabilityproblems in the resulting circuit. How well the operationsin each branch of a conditional statement can betested depends on the probability of taking each branchand the quality of the test patterns used in each branch.Behavioral modifications are presented that can resolvethese testability issues. Experimental results from threepractical examples show that this technique is effective.
