Abstract

A serial scan test architecture can perform testing of an electrical circuit without cycling through multiple data register shift operations required by conventional test architectures by permitting test signals to be transferred bidirectionally between serial scanning circuitry and functional circuitry while serial data is being transferred in a continuous serial data stream between the test controller and the serial scanning circuitry.
