Abstract :
A novel test controller architecture is presented that allows multiple IEEE 1500 wrapped cores within a SoC to be tested concurrently. The IEEE 1149.1 state machine is used to interface to the test controller allowing potential integration with the emerging IEEE P1687 (IJTAG) standard. Also included is a test access mechanism (TAM) methodology that reuses the physical connections of the SoC system bus to provide an efficient transport medium for test vectors between the test controller and IEEE 1500 wrapped cores.
