Abstract
Data in a data base that describe a logic circuit are converted to a simulation model, and simulations are performed based on them. When it is desired to change a part of the circuit while a simulation is in progress, a tentative correction is made by directly changing the simulation model without entering logics to the data base again. Simulation is continued based on the changed simulation model, then, after the action has been confirmed, the contents of the change are reflected on the data base. In this way, a circuit can easily be changed while simulation is in progress.
