Abstract :
As technology shrinks and working frequency reaches the multigigahertz range, designing and testing interconnects are no longer trivial issues. In this paper, we propose an enhanced boundary-scan architecture to test high-speed interconnects for signal integrity. This architecture includes: 1) a modified driving cell that generates patterns according to multiple transitions fault model and 2) an observation cell that monitors signal integrity violations. To fully comply with the conventional Joint Test Action Group Standard, two new instructions are used to control cells and scan activities in the integrity test mode.
