摘要

随着芯片变得越来越复杂,发现越来越多的内置DFX也就不足为奇了。这种内置的DFT显然有利于芯片/硅DFX工程师;然而,板级/系统级DFX工程师通常对DFX内置功能的访问权限有限。目前,电路板/系统级DFX工程师对在电路板/系统级重用芯片/硅DFX的需求不断增加。这个特别的会议将讨论:测试和诊断需要什么芯片访问板级?如何实现访问?IEEE P1687和IEEE 1149.1能解决这些问题吗?

Re-using chip level DFT at board level
As chips are getting increasingly complex, there is no surprise to find more and more built-in DFX. This built-in DFT is obviously beneficial for chip/silicon DFX engineers; however, board/system level DFX engineers often have limited access to the build in DFX features. There is currently an increasing demand from board/system level DFX engineers to reuse chip/silicon DFX at board/system level. This special session will discuss: What chip access is needed for board-level for test and diagnosis? How to accomplish the access? Will IEEE P1687 and IEEE 1149.1 solve these problems?
