1. A method for generating a behavioral model for a device, the device having a plurality of driver pins and a plurality of receiver pins, the method comprising: connecting the plurality of driver and receiver pins to a test apparatus including an input stimulation means, a voltage measurement means, and a current measurement means; stimulating a first set of the plurality of receiver pins using the input stimulation means; performing voltage measurements at selected ones of the plurality of driver pins using the voltage measurement means; stimulating a second set of the plurality of receiver pins using the input stimulation means; performing current measurements at selected ones of the plurality of driver pins using the current measurement means; and creating the behavioral model without using a functional model, said creating using the voltage measurements and the current measurements.
