During the simulation of a class of hybrid systems which consists of continuous systems, discrete event systems and inference decision systems, because the simulation of inference decision systems depends on the another two systems, there are only different private simulation clocks between continuous systems and discrete event systems. This paper studies their simulation clock synchronization problem, and the improved equal step length synchronization method which bases on the equal step length of continuous systems simulation, and the software realization method are given. At last, the performance valuation method is also given, which can provide theoretical basis for the simulation of this class of hybrid systems.
