<P>PROBLEM TO BE SOLVED: To enable collection of observation data at multiple observation points in an observation target circuit from a simulation accelerator in a realistic period. <P>SOLUTION: Upon receiving designation of observation points in an observation target circuit whose operation is to be observed in a simulation, circuit data of an observing circuit is added to circuit data of the observation target circuit stored in an observation target circuit data storage unit, so that the observing circuit is connected to the observation target circuit in accordance with data relating to the designation of the observation points. At that time, the observation circuit has a double buffer configuration and alternately outputs and stores, into a RAM, an occurrence frequency of a specific state at a specific observation point in a first period and an occurrence frequency of the specific state at the specific observation point in a second period. <P>COPYRIGHT: (C)2012,JPO&INPIT |
