Non-intrusive signal observation techniques usable for real-time internal signal capture for an electronic module or integrated circuit

摘要

Internal bus observation techniques for an electronic module or integrated circuit. In one embodiment, a disclosed apparatus includes observation logic to observe an observed bus and a debug buffer. The observation logic captures a record reflecting signal observed on the observed bus. The debug buffer is coupled to the observation logic to receive the record that reflects signal observed by the observation logic. The debug buffer generates a transaction to transfer the record to a storage device to store the record.
