Logic Proximity Bridge (LPB) patterns were proposed as an alternative to realistic bridge and ndetect patterns based on simulation studies. Here, silicon evaluation of logic proximity bridge patterns, on a mobile chipset product, is presented. Results show these patterns to significantly increase the class scan fallout above and beyond stuck-at patterns, consisting of single load and multi-load patterns, with very high stuck-at fault coverage. In addition it points to the usefulness of generating ATPG patterns using multiple fault models, LPB faults being one of them.
