Abstract

This article discusses the method of using the functional protocol of an existing high-speed I/O port for testing. This method enables reduced GPIO pin requirement during manufacturing test and running full structural content while embedded in a functioning system. Frequency of on-chip scan networks can be increased as it is no longer limited by pin timing bottlenecks of regular, slow-speed I/Os. The same HSAT-based test infrastructure can be used for enabling system-level and in-system test for monitoring throughout the lifecycle of the chip.

基于功能协议的高速I/O在大型SoC制造、系统级和系统内测试中的新技术

本文讨论了使用现有高速I/O端口的功能协议进行测试的方法。这种方法能够在制造测试期间降低GPIO引脚需求，并在嵌入功能系统时运行完整的结构内容。片上扫描网络的频率可以增加，因为它不再受到常规低速I/O的引脚定时瓶颈的限制。相同的基于HSAT的测试基础设施可以用于实现系统级和系统内测试，以便在芯片的整个生命周期中进行监控。
