摘要: A digital bus monitor used to observe data on a (14, 16, 18) connecting multiple integrated circuits (10, 12) comprises memory buffer (30), bypass register (34), test port (38) and output control (42, 46) controlled by an event qualifying module (EQM) (32). In response matching condition the EQM (32) may perform variety of tests incoming while continue operate at speed. plurality monitors (20, 22) be cascaded for observation variable width buses signature analysis.
