Embedded DfT Instrumentation: Design, Access, Retargeting and Case Studies
As semiconductor technologies enables highly advanced an complex integrated circuits (ICs), there is an increasing need to have more embedded design-for-test (DfT) instruments for test, debug, diagnosis, configuration, monitoring, etc. As these instruments are to be used not only at chip-level but also at board-level and system-level, a key challenge is how to access these instruments from chip te
