摘要: 低功耗技术,如多电源多电压和电源关断等的应用,给现代超大规模系统芯片可测试性设计带来诸多问题。为此,采用工业界认可的电子设计自动化工具和常用的测试方法,构建实现可测试性设计的高效平台。基于该平台,提出一种包括扫描链设计、嵌入式存储器内建自测试和边界扫描设计的可测性设计实现方案。实验结果表明,该方案能高效、方便和准确地完成低功耗系统芯片的可测性设计,并成功地在自动测试仪上完成各种测试,组合逻辑和时序逻辑的扫描链测试覆盖率为98.2%。

Abstract: The low power design technologies such as Multi-supply Multi-voltage(MSMV) and Power Shut-off(PSO), present many challenges for the testability design of modern very large scale integration System-on-chip(SoC). Based on the efficient implementation platform constructed by using the industrial electronic design automation tools and the widely used testability methods, a testability design scheme that includes the scan chain, memory built-in-self-test and boundary scan is proposed. Experimental results show that the scheme can efficiently, conveniently and accurately complete the testability design of low power consumption SoC, and works correctly in automation test equipment. The test coverage of combinational and sequential logic scan chains is 98.2%.

Key words: testability design, low power consumption, System-on-chip(SoC), built-in-self-test, Power Shut-off(PSO), Multi-supply Multi-voltage(MSMV), scan chain
