Timing verification method and device

摘要

There is disclosed a timing verification device for a synchronous circuit/asynchronous circuit mixed circuit which can verify timings of a synchronous circuit portion and an asynchronous circuit portion by means of a static timing verification. In an electric or electronic circuit, for a circuit mixed with a synchronous circuit which is synchronous with a specified clock signal and an asynchronous circuit which has no specified clock or is not synchronous with the specified clock signal, a verifying means is provided for assuring a timing only in a static timing verification method. <IMAGE>
