Abstract

This paper presents a method for deriving a BIST specification from the initial specification of datapaths. This method minimizes BIST area overhead under test time constraint while guaranteeing a user chosen fault coverage. The designer can thus explore a wide range of solutions and keep the one that best fits with design constraints. Results show great improvements over lower level techniques.
