ABSTRACT:
A method of testing a core module includes steps of: (a) providing a core module of an integrated circuit design; (b) connecting an end user input and a core module test input to separate I/O pins of the core module to isolate logic associated with an end user signal from that associated with a core module test signal; and (c) multiplexing the end user signal and the core module test signal in the core module in response to a core module test mode signal.
