SYSTEM AND METHOD TO PERFORM SCAN TESTING USING A PULSE LATCH WITH A BLOCKING GATE

摘要

A system and method to perform scan testing using a pulse latch with a blocking gate is disclosed. In a particular embodiment, a scan latch includes a pulse latch operable to receive data while a pulse clock signal has a first logical clock value and a blocking gate coupled to an output of the pulse latch. The blocking gate is operable to propagate the data from the output of the pulse latch while the pulse clock signal has a second logical clock value.
