Abstract
Disclosed is an integrated circuit (IC) chip with a built-in self-test (BIST) architecture that allows for in the field accelerated stress testing. The IC chip can comprise an embedded processor, which selectively alternates operation of an on-chip test block between a stress mode and a test mode whenever the IC chip is powered-on such that, during the stress mode, the test block operates at a higher voltage level than an on-chip functional block and such that, during the test mode, the test block operates at a same voltage level as the functional block and is subjected to testing. Also disclosed are a system, method and computer program product which access the results of such testing from IC chips in a variety of different types of products in order model IC chip performance degradation and to generate IC chip end of life predictions specific to the different types of products.
