If the Petri Net technique is used for nonlinear random analysis, some researches on statistical and continuous properties from the point of view of definition and emission rule should be made. Based on the requirement of analyzing the random nonlinear property of integrated circuits, the paper proposed a Hybrid Statistical Petri Net (HSPN) extended from traditional Petri Net. Derived from hybrid automat a model of nonlinear circuits, the capability of describing statistical transition has been enhanced. According to the circuit noise, HSPN based statistical dynamic model is presented. And the modeling methods are illustrated by a sample circuit. Comparing with SPICE simulation tool, the feasibility of this method is verified.
