Patent ID: 7324932

Claim:
A computer implemented method for designing a tester interface unit for use with an actual electronic device, comprising: simulating a virtual device with an input test signal emulating an actual input signal to be applied to the actual electronic device during testing; determining, in a virtual test environment, an indication of a signal transmission time of the actual electronic device in an actual test environment; determining, in the virtual test environment, an indication of a signal transmission time of the actual electronic device in the environment where the actual electronic device will ordinarily be used; evaluating the integrity of the input test signal and a resulting output signal from the virtual device based on the determined indication of the signal transmission time of the actual electronic device in the actual test environment and the determined indication of the signal transmission time of the actual electronic device in the environment where the actual electronic device will ordinarily be used; and using the evaluation of the integrity of the input test signal and the resulting output signal from the virtual device to design the tester interface unit for use with the actual electronic device.
