Abstract

There is provided a tester interface circuit for use with a BIST state machine and a method for micro-architectural implementation of the same so as to enable cycling through a BIST test. The tester interface circuit includes a storage device, a logic decoder, a set/clear mechanism, and a polling logic device. The tester interface circuit is implemented with a minimum amount of chip area on a semiconductor IC.
