  • Test vector verification system
    Patent number: 6223272
    Abstract: The present invention relates to a verification system for verifying whether vector outputs from a software simulator match the vector outputs from a hardware emulator by comparing a pair of checksums. A first checksum value is calculated from the output vectors obtained from the software simulator and a second checksum is calculated from the output vectors obtained from the hardware emulator. Accordingly, only a checksum value is required to be downloaded or uploaded, thereby eliminating the need to upload or download large numbers of output vectors.
