Abstract
A method of using a processor-based integrated circuit (IC) tester (12) to automatically invoke diagnostic testing. A diagnostic schedule (30) is user-defined (FIG. 3), and checked by the tester (12) at various times, such as before and after the tester 12 tests an IC lot (FIGS. 6, 7, 8). The schedule (30) has various scheduling parameters that permit diagnostic testing to be scheduled to occur at certain times, at the expiration of intervals, or upon certain events. The schedule (30) also permits different levels of diagnostic testing, each level with its own schedule. The tester (12) is programmed to run an appropriate level of diagnostic testing if more than one level is due to occur.
