Method and system for sequential equivalence checking with multiple initial states

摘要

A method, system and computer program product for performing equivalence checking of a circuit design are disclosed. The method includes importing a first design comprising a first register set and a different second design comprising a second register set and importing a mapping between corresponding initial states of the first register set and the second register set. A first random logic and a second random logic, respectively representing an application of a set of initial values to the first register set and the second register set are generated and an equivalence check on a third design synthesized from the first design and the second design with an output set from the first random logic as an initialization of the first register set and with an output set of the second random logic as an initialization of the second register set is performed.
