    VLSI/VHSIC technology poses critical test problems not only at the device level, but also at the system level. The extreme functional complexity and fail-operational redundancy of VLSI systems tends to render conventional performance testing inadequate, not only in terms of failure mode coverage, but also in terms of test-time requirements. The authors propose a design structure in which various s... View full abstract»
