摘要： Apparatus and techniques for performing JTAG testing on production devices and systems through industry standard interfaces. The devices employ processors configured to receive packetized test input data from a tester over a standard communication interface such as a USB or Ethernet port and perform associated testing operations defined by the test input data, such as JTAG-compliant testing. This is facilitated, in part, via use of a bridge and one or more DFx handlers, with the bridge operating as an interface between the DFx handlers and a bus and/or interconnect over which test input and result data is transferred via the standard communication interface. The techniques enable testing such as JTAG testing to be performed on fully-assembled devices and systems without requiring the use of dedicated test or debug ports.
