Abstract

Built-in self-test (BIST) microcontroller integrated circuit adapted for logic verification. Microcontroller includes a plurality of hardware description language files representing a hierarchical description of the microcontroller, the plurality of hardware description language files including a library of circuit design elements, a plurality of library design circuit elements adapted to store a uniquely defined set of input and output signals to enable a logic BIST, and a plurality of latches adapted to store a plurality of values corresponding to a behavioral profile of a test clock.
