Abstract:
A logic built-in self-test (LBIST) module and a method of online system testing. In one embodiment, the LBIST module includes: (1) first and second data sources selectable to provide alternative respective first and second data to at least one scan chain and (2) a scan clock modifier associated with the first and second data sources and configured to drive the at least one scan chain with a selectively aperiodic modified scan clock signal.
