Abstract

See full text

Two or more independently clocked simulators are interconnected in a manner which prevents signal exchange at a time when the internal simulation clocks of the simulators point to different times on a simulated time line. Each simulator transmits to one or more of the other simulators in its network information indicaitng the next point in simulated time at which the transmitting simulator can model a state change which might affect a model part being simulated by the receiving simulator. Blocking means are provided for blocking the receiving simulator from advancing its simulated time clock ahead of the next state change time of the transmitting simulator. The receiving simulator is free, however, to operate at its maximum speed for simulated time spans occurring before the next state change time of the transmitting simulator.
