Design of Efficient Hardware Utilization Fault Coverage Circuit
نویسنده
چکیده
A new fault coverage test pattern generator using a linear feedback shift register (LFSR) called FC-LFSR can perform fault analysis and reduce the power of a circuit during test by generating three intermediate patterns between the random patterns by reducing the hardware utilization. The goal of having intermediate patterns is to reduce the transitional activities of Primary Inputs (PI) which eventually reduces the switching activities inside the Circuit under Test (CUT) and hence power consumption is also reduced without any penalty in the hardware resources. The experimental results for c17 benchmark, with and without fault confirm the fault coverage of the circuit being tested. KeywordsLFSR, Optimization, Low Power, Test Pattern Generation, BIST

Implementation of Low Power Circuit Analysis with Applications of Test Vectors
An advanced approach to design a fault coverage test pattern generator by utilizing linear feedback shift register called Bit Swap-LFSR. This could perform fault analysis and also minimize the power utilization at circuit level during tests, by generating three intermediate patterns between random patterns by decreasing the hardware components usage. The main purpose of having intermediate patt...
