| 摘 要： | Petri网是异步并发现象建模的重要工具,以异步处理器为代表的异步电路以其在解决时钟扭曲,低功耗方面的优势受到越来越广泛的关注,异步电路设计的主要问题之一是缺乏成熟的EDA工具支持异步电路的设计风格,采用基于信号转换图(STG)的方法,完成了一个基于握手协议的异步控制部件的Petri网模型建立以及仿真和实现。并进一步给出了一个异步FIFO的设计应用实例。通过标准的时序仿真方法,得到的仿真结果表明上述方法能够很好地完成异步电路的设计而且在综合效率和资源利用上有明显的改进。

| Abstract: | This paper presents a model of asynchronous circuit by using Petri net method.Petri Net is an important tool for modeling asynchronous and subsequent events.The asynchronous circuit represented by asynchronous processor is increasingly concerned for its advantage in solving clock skew and reducing power consum.A major problem is the absence of mature asynchronous CAD tools to support the asynchronous design style.Based on the STG(signal transform graph),a Petri model of an asynchronous controller is establi... |
