    摘要: A method for verifying the equivalence of two representations of a stimulus pattern for testing a design is disclosed. The method includes receiving a base pattern file representing the stimulus pattern in a first file format. A derivative pattern file in a second file format is generated from the base pattern file. The derivative pattern file is parsed to create a first testing file in a third file format, and the first testing file is simulated against the design in a first simulation. Whether the first testing file passed the first simulation against the design is determined, and in response to determining that the first testing file does not pass the first simulation against the design, the base pattern file is parsed to create a second testing file in the third file format. The second testing file is simulated in a second simulation. Whether the second testing file passed the second simulation is determined, and, in response to determining that the second testing file passed the second simulation, a likely non-equivalence of the derivative pattern file and the base pattern file is indicated. In response to determining that the second testing file did not pass the second simulation, a likely equivalence of the derivative pattern file and the base pattern file is indicated.
