  • Tester-compatible timing translation system and method using time-set partnering
    Patent number: 6067652
    Abstract: A system comprises translation software to convert non-tester-compatible simulation results into tester-compatible test patterns in a ATE system. An intermediate output of the system includes tester-compatible input stimulus for use in re-simulating a circuit design. The resulting simulation output data is tester-compatible, by definition, and can be used to generate tester-compatible test patterns that correspond to a verified simulation of the circuit design. Partnered time sets and signal state data are used in translation between tester-compatible and non-tester-compatible timings.
