Abstract
A method is provided that provides a test of an interconnect that communicates information between two digital circuits. One of the digital circuits is constructed to be 'scannable' so that it at least includes scannable registers capable of applying signals to, and sampling signals at, the interconnect. The other digital circuit has a different scan architecture such as, for example, that specified by IEEE Standard 1149.1. The method allows the interconnect between the two digital circuits, each having scan architecture that is not compatible with that of the other, to be tested.
