Abstract :
We present a system which synthesizes, from a behavioral description, an RTL circuit which is testable with a high degree of test concurrency. The system produces a datapath containing test registers, and a BIST test plan for the testing of the chip. All design decisions are made using an estimate of test conflicts, which is based on an analysis of the reachability of each component port from I/O pins and test registers. Chip testing according to the partial-intrusion BIST methodology is assumed. Empirical results show the effect of test conflicts on the test application time, and highlight the benefit of using the proposed synthesis approach for test conflict reduction
