Abstract
A computer-implemented method for augmenting SAT-based BMC to handle embedded memory designs without explicitly modeling memory bits. As is known, verifying designs having large embedded memories is typically handled by abstracting out (over-approximating) the memories. Such abstraction is not useful for finding real bugs. SAT-based BMC, as of now, is incapable of handling designs with explicit memory modeling due to enormously increased search space complexity. Advantageously, our method does not require analyzing the designs and also guarantees not to generate false negatives.
