Abstract:
Built-in self-test techniques for integrated circuits that address the issue of unknown states. Some implementations use a specialized scan chain selector coupled to a time compactor. The presence of the specialized scan chain selector increases the efficiency in masking X states. Also disclosed are: (1) an architecture of a selector that works with multiple scan chains and time compactors, (2) a method for determining and encoding per cycle scan chain selection masks used subsequently to suppress X states, and (3) a method to handle an over-masking phenomenon.

Claim (Index 17):
The method of  claim 15 , wherein the generating the mask data comprises selecting one or more of the scan cells based on the number of times an unknown state reaches the scan cells, the number of times faults are observed at the scan cells, or the number of times an unknown state reaches the scan cells and the number of times faults are observed at the scan cells, through a series of the received test responses.
