MULTIPLE USES FOR BIST TEST LATCHES
摘要:
A method, an apparatus, and a computer program are provided to utilize built-in self test (BIST) latches for multiple purposes. Conventionally, BIST latches are single purpose. Hence, separate latches are utilized for array built-in self test (ABIST) and logic built-in self test (LBIST) operations. By having the separate latches, though, a substantial amount area is lost. Therefore, to better utilize the latches and the area, ABIST latches are reconfigured to utilize some previously unused ports to allow for multiple uses for the latches, such as for LBIST.
