Research on the design for test of Combinatorial Circuit
Author(s): 
Pages: 38-41
Year: Issue:  5
Journal: ELECTRONIC MEASUREMENT TECHNOLOGY

Keyword:  组合电路内建自测试线性反馈移位寄存器;
Abstract: 随着集成电路设计规模的不断增大,在芯片中特别是系统芯片SOC(system on a chip)中组合电路的可测试性设计方法变得越来越重要.本文采用内建自测试技术对组合电路进行可测试性设计,详细分析了组合电路内建自测试的实现原理.通过将测试生成及响应分析逻辑置入电路内部,提高了电路的可控制性和可观察性,从而可使该电路的测试和诊断快速而有效.最后对8位行波进位加法器的内建自测试设计过程进行了详细分析,并通过MAX+pluslI将其实现.
