  • Method and apparatus for high update rate integrated circuit boundary scan
    Patent number: 7039840
    Abstract: Boundary scan cells for driving internal logic and sensing internal logic of integrated circuit use external clocks synchronized with internal functional clocks. Synchronized clocks enable synchronous sampling of internal signals and synchronized of injection signals into a functional portion of the integrated circuit.
    Type: Grant
