摘要

利用元胞自动机(CA)生成内置自检(BIST)应用程序的伪随机数在本工作中得到了强调。在最大长度CA (MaxCA)的基础上,提出了等长CA (ELCA)的伪随机模式生成方法,提高了生成过程的成本效益。与基于MaxCA和基于线性反馈移位寄存器(LFSR)的BIST模式发生器相比,ELCA生成的BIST模式具有更高的故障覆盖质量。所提出的基于ELCA的模式发生器在降低BIST模式发生器的故障覆盖开销方面发挥了重要作用。在建议的设计中,在生成的模式中保持高度的随机性,重点是减少一些主要的相关复杂性,如设计复杂性、时间复杂性和搜索复杂性。实验结果表明,本文提出的基于ELCA的BIST应用具有较高的随机性和相对较高的故障覆盖率。

Cost effective PRNG using ELCA: A BIST application
Generation of pseudo-random numbers using Cellular Automata (CA) for Built-In-Self-Test (BIST) applications has been emphasized in this work. Enhanced cost effectiveness is achieved for the generation procedure of pseudorandom patterns with proposed Equal Length CA (ELCA) with reference to Maximum-length CA (MaxCA). Proposed ELCA scheme generates patterns for BIST and achieves higher quality of fault coverage compared to MaxCA and Linear Feedback Shift Register (LFSR) based BIST pattern generator. Proposed ELCA based pattern generator is significantly contributing a role in overhead reduction of fault coverage for BIST pattern generator. A high degree of randomness is maintained in generated patterns in proposed design focusing on the reduction of some major associated complexities such as design complexity, time complexity and searching complexity. Experimental results have ensured that high degree of randomness and comparative high degree of fault coverage are achieved for proposed ELCA based BIST application.
