PURPOSE:To simply and flexibly measure the internal virtual time of simulation. CONSTITUTION:A processing routine 6 included in a simulation process 2 is started by an operating system 5 when the process 2 runs for a fixed time (with use of a CPU). Then the routine 6 advances the virtual time in the process 2. Thus it is not required to advance the time for each processing unit in the process 2. As a result, a program is simplified and at the same time the overhead is reduced. |
