Latest Patents

Daniel R. Pfunder holds a patent titled "Packetizing JTAG across industry standard interfaces." This patent describes an apparatus and techniques for performing JTAG testing on production devices and systems through industry standard interfaces. The devices utilize processors that are configured to receive packetized test input data from a tester over standard communication interfaces such as USB or Ethernet ports. They perform associated testing operations defined by the test input data, including JTAG-compliant testing. This process is facilitated by the use of a bridge and one or more DFx handlers, with the bridge serving as an interface between the DFx handlers and a bus or interconnect over which test input and result data is transferred. The techniques enable JTAG testing to be performed on fully-assembled devices and systems without the need for dedicated test or debug ports.
