ABSTRACT:
A boundary-scan circuit method and apparatus for asserting an internal reset signal connected to core logic circuits of an electronic device in order to assure that testing will begin and end in a safe, known logic state. A safe end state is assured even if the system reset signal on an input pin of the electronic device is logically disconnected from the internal reset connection to the core logic, as often occurs in boundary-scan and related testing.
