  • Method and apparatus for configuring plurality of devices on printed circuit board into desired test port configuration
    Patent number: 7752004
    Abstract: A system on a circuit board includes a plurality of devices designed to access an electronic system on the circuit board, and a programmable logic device (PLD) connected to the plurality of devices. Each of the plurality of devices complies with a test port architecture. The PLD interfaces the plurality of devices with a test port. The PLD is capable of configuring different connectivity among the plurality of devices based on the program implemented and the assertion of input control signals. A method and apparatus configures a plurality of devices on a circuit board into a desired configuration using the PLD. The configuration includes (a) receiving a control signal at the PLD, (b) configuring at least one of the plurality of devices into a chain based on the control signal, and (c) coupling the configured chain to the test port via the PLD.
