1. A method of simulating a logic system, comprising the steps:

  • (a) maintaining a data structure representing a cyclic time loop having a plurality of time slots, each time slot being associated with a plurality of different simulation time values corresponding to successive cycles around the time loop,(b) inserting simulation events into the time slots, each event having an event time value, and each event being inserted into a time slot corresponding to the event time value of that event, events with different event time values corresponding to different cycles around the time loop being simultaneously present in a single time slot,(c) maintaining a current simulation time value, and incrementing said current simulation time value to simulate passage of time, and(d) accessing the time slot corresponding to the current simulation time value, comparing the event time values of events in that time slot with the current simulation time value, and processing only events in that time slot whose event time values are equal to the current simulation time value.
