Abstract
A semiconductor device-under-test (DUT) may be tested by an automated test system that processes test programs specifying a number of edges per tester cycle that may be greater than the number of edges the tester is capable of generating. The test system may include circuitry that reduces the number of edges in each cycle of a test program based on data specifying operation of the tester in that cycle and/or a prior cycle. Such a reduction simplifies the circuitry required to implement an edge generator by reducing the total number of timing verniers per channel. Nonetheless, flexibility in programming the test system is retained.
