摘要

描述了一种使用寄存器传输电平(RTL)部分扫描选择的自顶向下可测试性设计方法。我们提出了一种基于可测试性分析的扫描选择技术,用于RTL设计,包括数据路径电路和状态机等控制电路。采用基于RTL可测性分析的扫描选择技术,有效地识别了使门级ATPG难以实现的寄存器和状态机。给出了实际电路的实验结果。

Design for testability using register-transfer level partial scan selection
An approach to top down design for testability using register-transfer level (RTL) partial scan selection is described. We propose a scan selection technique based on testability analysis for RTL design including data path circuits and control circuits such as state machines. Registers and state machines which make gate level ATPG difficult are identified by the scan selection technique based on RTL testability analysis effectively. Experimental results for actual circuits are also presented.
