VHDL语言特性分析

Analyze the Characteristic of VHDL

简单概述了VHDL语言的并行语句和顺序语句,描述了其种类和特点。给出了一段同步整形电路的代码,结合用QuartusII仿真得到的波形图,详细地分析了代码的执行过程。通过分析这段代码,可以了解用VHDL语言设计时序电路的最核心的语句——进程的用法,以及利用信号的赋值实现多个进程间通信的方法。

Summarized the concurrent statements and sequential statements of VHDL language,and described their types and the char-acteristic . Showing a section of code about synchronized shape shifter circuit,unified an image which obtains form the Quartus II simu-lation, and analgzed code implementation step by step.
