A Seed-Calculation Method on Dynamic Coverage Improvement Threshold
Jianjun Liu · Microelectronics & Computer · 2008
This paper presents a new approach which can supplies the seeds for the linear feedback shift register(LFSR) reseeding on the dynamic coverage improvement threshold(DCIT).The method is simple and effective.After reseeding with the seeds which are calculated by this way,the ineffective pseudo-random test vector sequence will be truncated.Every seed produces the same length pseudorandom test patterns.The experiments on ISCAS85 benchmark circuits demonstrate that the scheme can reduce the test patterns length,shorten the test time and decline the test power consumption.
