REMOTE BUS WRAPPER FOR TESTING REMOTE CORES USING AUTOMATIC TEST PATTERN GENERATION AND OTHER TECHNIQUES

A wrapper for automatic test pattern generation uses the functional bus when testing cores on an integrated circuit device. The functional bus is between the bus wrapper and the cores. During normal operation, the functional bus operates as a standard bus to communicate functional inputs and outputs...

Summary:A wrapper for automatic test pattern generation uses the functional bus when testing cores on an integrated circuit device. The functional bus is between the bus wrapper and the cores. During normal operation, the functional bus operates as a standard bus to communicate functional inputs and outputs between the cores and in/out of the integrated circuit device. During test operation, test signals are communicated on the functional bus. As a result, each core does not require its own wrapper; this allows the bus wrapper to reduce the area occupied by test circuitry.
