Abstract
A system and method for manipulating waveforms, including transaction cancellation, in parallel time-warp simulation of circuits, such as those modeled in VHDL. Events waveforms for each output of a processor are organized by the simulation time (ST) of the events which created them and by the simulation time (RT) at which they are to be effective. A phantom buffer provides a linked list of events and associated transactions cancelled as a result of insertion of a new event in said chain of events. Rollback of a cancelled event waveform is done by restoring to the linked lists selected events and transactions from the phantom buffer.
