Abstract
Testing of an electronic system is optimized by using a single set of sub-tests and varying the testing sequence to produce tests tailored for different purposes such as screening and diagnostic testing. For example, a programmable test sequencer in the electronic system responds to a test selection variable by using a first sequence of the sub-tests to optimize the testing process for screening and a second sequence of the sub-tests to optimize the testing process for diagnostic testing. In the diagnostic mode, the sub-tests are run so that each sub-test builds upon the previous sub-tests and uses previously-tested hardware to verify additional hardware. In the screening mode, the sub-tests are the same, but the execution order of the sub-tests is reversed so that more complex hardware is tested first as a screening mechanism.
