Abstract
An integrated circuit tester is described that utilizes methods of programming parallel coupled Algorithmic Pattern Generators (APGs) to generate test vector sequences and part commands with sub-instruction repeats. This enables simpler test programming and ease of test conversion to new part speed grades, steppings, or part designs. In one embodiment, a sub-instruction repeat is utilized to enable adjustment of the timing of test vector sequences and part commands sent to an integrated circuit device under test (DUT) so that the test can be adjusted for new part speed grades and/or steppings. In another embodiment, a sub-instruction repeats are utilized to enable adjustment of the timing of a memory device inputs, memory commands and test vector sequences so that the test can be adjusted for new memory device speed grades.
