Abstract: This paper studies how to use Very high-speed integrated circuit Hardware Description Language(VHDL) to describe a Petri net subclass——Place/Transition(P/T) system. The VHDL description of Petri net model is compiled, simulated, fit design and finally downloaded to Field Programmable Gate Array(FPGA) through Electronic Design Automation(EDA) software MAX+plusII. Hardware experiment is performed with GW48-CK. A P/T system example——service system is described and implemented using the proposed method. Simulation wave and hardware experiment further verify the correctness of the method. The VHDL-based implementation method is of great significance to the design of parallel controller based on P/T System.

Key words: Petri net, Place/Transition(P/T) system, Electronic Design Automation(EDA), Hardware Description Language(HDL), Programmable Logic Device(PLD)

摘要： 利用超高速集成电路硬件描述语言(VHDL)描述P/T系统，在EDA软件平台MAX+plusII上，对Petri网模型的VHDL描述进行编译、仿真、适配，将结果下载到可编程逻辑器件中，通过实验开发系统GW48-CK进行硬件测试。给出一个P/T系统实例——服务系统的描述及实现。仿真波形及硬件测试结果证明了该方法的正确性。
