Abstract
An all events trace gatherer for a logic simulation machine is disclosed. The all events trace gatherer generates an all events trace (AET) which is a record of what has happened to all or a subset of the facilities by monitoring a simulation bus on which the logic simulation machine put a calculated result during the simulation thereon. The AET gatherer allows an AET to be gathered without slowing the simulation. The AET gatherer is an auxiliary processor that is connected to the simulation bus in the logic simulation machine in parallel with simulation processors of the machine.
