ABSTRACT:
A method of operating an integrated circuit (IC) tester is disclosed in which an IC is repeatedly tested with respect to a limited number of combinations of values of two variable IC operating parameters (X and Y) to determine the boundary of a two-dimensional range of combinations of values of the X and Y parameters for which the IC passes a test. After finding a combination of X and Y parameter values on the boundary, each combination of parameter values to be tested thereafter is selected by altering either the X or Y parameter value, with the decision based on whether the IC passed the last test and on the manner in which a last tested combination of X and Y parameter values was selected.
