Abstract :
A unified solution to the problems that arise in the design, development, and test of VLSI processors is offered. The JTAG/IEEE P1149.1 standard boundary-scan architecture is proposed as the basis for designing testable, defect-tolerant, VLSI processors. The test access port (TAP) provided by the boundary-scan architecture is used to control and repair the microprogram control unit, as well as to control and observe key control and data values. Built-in self-test and boundary-scan are used to solve other test problems. The TAP is also used to provide a measure of defect tolerance
