VHDL语言教程(精华)
VHDL语言的简化教程pdf,通过文档可以全面了解VHDL的语法。VHDL概述:●●●●ⅤHDL→Ⅴ HSIC Hardwarter Description LanguageⅤHSIC→Ⅴ ery High speed integrated circuitVHDL是美国国防部在20世纪80年代初为实现其高速集成电路硬件ⅤHSIC计划提出的描述语言;IEEE从1986年开始致力于ⅤHD标准化工作,融合了其它ASIC芯片制造商开发的硬件描述语言的优点,于93年形成了标准版本( IEEE std1164)。1995年,我国国家技术监督局推荐ⅤHDL做为电子设计自动化硬件描述语言的国家标准。●●●●VHDL优点●●0覆盖面广,系统硬件描述能力强,是一个多层次的硬件描述语言;VHDL语言具有良好的可读性,既可以被计算机接受,也容易被人们所理解;ⅤHDL语言可以与工艺无关编程;VHDL语言已做为一种IEEE的工业标准,便于使用、交流和推广。VHDL语言的不足之处设计的最终实现取决于针对目标器件的编程器,工具的不同会导致综合质量不一样31VHDL语言基础●●●●3.1.1标识符( Identifiers)●●0标识符用来定义常数、变量、信号、端口、子程序或参数的名字,由字母(A~z,a-z)、数字(0-9)和下划线()字符组成。要求:●首字符必须是字母未字符不能为下划线●不允许出现两个连续的下划线不区分大小写●ⅥHDL定义的保留字(关键字),不能用作标识符●标识符字符最长可以是32个字符。注释由两个连续的虚线(--)引导关键字(保留字)●●●●关键字( keyword)是VHDL中具有特别含义的单词,只●●0能做为固定的用途,用户不能用其做为标识符。BJ]0: ABS, ACCESS, AFTER, ALL, AND, ARCHITECTUREARRAY ATTRIBUTE.
