发明名称 Test vector verification system
摘要 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. The system includes a software simulator for generating a set of input and output vectors, a checksum calculator for calculating the checksum of the output vector generated by the software simulator, a hardware emulator for receiving and storing the vector inputs and the checksum value generated by the software simulator and for generating output vectors based on the downloaded input vectors, a checksum calculator for calculating the checksum of the vector outputs generated by the hardware emulator and a checksum comparator for comparing the checksums.
