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?
