摘要
随着EDA技术的发展,利用VHDL语言描述有限状态机(FSM),得到广泛应用研究。本文通过举例,利用VHDL语言描述了不同模式的有限状态机,分析了有限状态机在PLD中综合的特点。同时,本文中对不同描述风格的有限状态机在PLDEMP7032中综合的特性进行了比较分析。可以看出,不同的模式、不同的描述风格,对有限状态机的特性具有较大的影响。这一结果,为在实际的设计中,对有限状态机的VHDL语言设计的优化提供了有效的参考依据。
With developing of EDA technique, using VHDL language describes FSM is in broad use. Different pattern of FSM were described through VHDL language in this paper. We also analyzed characteristic of synthesis of FSM on PLD by giving an example in the paper. At the same time, the different characteristic in different description style of FSM synthesized on the EMP7032 was compared. Comparing results show that different patter, different description all contributes to the characteristic of FSM,which provide us a solid reference basis for the VHDL language optimization for FSM.
