Embodiment 1

[0075] The present invention has realized conversion tool PN3MSVL and PN4MSVL, and they are integrated in the tool collection MSVToolkit, as figure 2 shown; in addition, this MSVToolkit also includes the existing modeling tool Workcraft of the Petri net system and the existing supporting tool MSV of MSVL; t) introduces the variable q(t) of the same name instead of the variable v q (v t );

[0076] Such as image 3 Shown, it is the Petri net system Z in this embodiment; This embodiment shows how to utilize tool MSV to carry out the verification of the various semantics of Petri net system simulation, modeling and complete regular property;

[0077] Specific steps:

[0078] step one:

[0079] Click the button Workcraft of MSVToolkit to call the modeling tool Workcraft of the Petri net system to build the model of Z and save it to the 1.g file;

[0080] Step two:

[0081] Click the button Input to select the 1.g file, click the button Output to select the output path of t...

Abstract

The invention discloses a Petri net model detection method based on MSVL. Firstly, the existing modeling tool Workcraft is used to establish a Petri net system model, and then the model is converted into an equivalent MSVL program. For this reason, the invention provides respectively Three conversion methods guided by the sequential semantics, parallel semantics and maximum parallel semantics of the Petri net system; finally use the existing MSVL support tool MSV to simulate, model and verify the generated MSVL program. For the conversion method above, the present invention develops conversion tools PN3MSVL and PN4MSVL, so that the tool MSV can analyze and verify various semantics of the Petri net system. The invention solves the problem that the existing Petri net model detection method is difficult to fully verify the complete regularity of various semantic meanings.

Description

technical field [0001] The invention belongs to the technical field of Petri net model detection, in particular to a Petri net model detection method based on MSVL. Background technique [0002] As a graphical and formal tool, Petri nets are widely used in modeling and analyzing discrete event systems. The graphics of Petri nets can express complex requirements intuitively, but vague text descriptions or obscure mathematical symbols cannot. In addition, the mathematical theory of Petri nets can be used to formally analyze some properties of the system model (such as accessibility, security and activity). The existing Petri net analysis methods include covering tree method, net simplification method and net expansion method. In addition, a variety of model checking methods have been proposed for Petri nets, such as partial order model checking, symbolic model checking and bounded model checking. These methods allow the verification of properties described in Linear Tempora...
