Abstract

We present the application of a deterministic logicBIST scheme on state-of-the-art industrial circuits. Experimental results show that complete fault coverage canbe achieved for industrial circuits up to 100K gates with10,000 test patterns, at a total area cost for BIST hardwareof typically 5%-15%. It is demonstrated that a tradeoffis possible between test quality, test time, and silicon area. In contrast to BIST schemes based on test point insertionno modifications of the circuit under test are required,complete fault efficiency is guaranteed, and theimpact on the design process is minimized.
