Abstract
A circuit simulator performs a simulation for each tester using, as input values, tester parameters, test board parameters, and chip parameters. A difference acquiring section produces difference data of simulation results. A program converting section converts a test program for a first tester into a test program for a second tester based on the produced difference data. With this program conversion system, the load of tester replacement work can be reduced in the case where LSI products need to be tested by using different testers.
