METHOD AND SYSTEM FOR TEST VERIFICATION OF INTEGRATED CIRCUIT DESIGNS
First Claim
1. A method for verifying the design of an integrated circuit including an analog portion and a digital portion, comprising the steps of:
- generating an analog stimulus;
performing a simulation test of the analog portion of the integrated circuit using the analog stimulus as an input;
collecting data at an output of the analog portion of the integrated circuit;
generating a digital stimulus with the collected data;
performing a simulation test of the digital portion of the integrated circuit using the digital stimulus as an input;
validating data at an output of the digital portion of the integrated circuit;
regression testing the digital portion of the integrated circuit using the digital stimulus as an input; and
comparing a result of the regression testing step with a result of the validating data step.
