摘要

本文介绍了R10000微处理器的可测试性设计特点。它具有用于调试和制造目的的特定可测试性特性。可观察性寄存器的实现提高了故障覆盖率,可观察性寄存器将芯片划分为三部分以更快地运行故障模拟。此外,还实现了用于交流路径分析的时钟控制机制和最小影响嵌入式存储器测试功能。

Testability features of R10000 microprocessor
This paper describes the testability design features of the R10000 microprocessor. It has specific testability features for debug and manufacturing purposes. Observability registers are implemented to enhance high fault coverage and they partition the chip into three parts to run a fault simulation much faster. Plus a clock control mechanism for AC path analysis and a minimal impact embedded memory test feature are implemented.
