Beginner VHDLTraining Class VHDL初学者入门 Danny Mok Altera HK FAE (dmok@) What is VHDL(什么是VHDL) Very high speed integrated Hardware Description Language (VHDL) 超高速集成硬件描述语言 is an industry standard hardware description language description the hardware in language instead of graphic easy to modify 是一种工业标准硬件描述语言; 用语言 easy to maintain 代替图形描述硬件;易修改;易维护 very good for 非常适合于 complex combinational logic 复杂组合逻辑 BCD to 7 Segment converter BCD-七段码转换器 address decoding 地址解码 state machine 确定机器状态 more than you want……..更多你想做的…… What VHDL Standard means??(VHDL 标准的含义) The VHDL is used to describe VHDL用于描述 Inputs port -输入口 Outputs port -输出口 behavior and functions of the circuits 电路的状态和功能 The language is defined by two successive standards IEEE Std 1076-1987 (called VHDL 1987) IEEE Std 1076-1993 (called VHDL 1993) 该语言由上述两种标准连续定义 Altera VHDL Altera Max+Plus II support both VHDL 1987 and 1993 (ALTERA MAX+PLUSII 支持上两种标准) Max+Plus II only support SUBSET of the two IEEE standard(MAX+PLUSII 仅支持两个IEEE标准的子集) Detail of the support can be referred to Altera Max+Plus II VHDL handbook on page 89 Section 3 (支持的细节请参考Max+Plus II VHDL 手册89页3段) How to use the VHDL 如何使用VHDL use any text editor to create the file 用任意文本编辑器建立文件 Altera Software Max+Plus II provides text editor ALTERA软件也有文本编辑器 建立自己的VHDL文件 create your VHDL file 把你的文件存为name.VHD save your VHDL file as name.VHD 选择VHDL标准版编码 Select the Standard Version of VHDL coding 1987 or 1993 编译你的VHDL文件 Compile your VHDL file Bonus Topic may help forVHDL DesignwithinMax+Plus II MAX+PLUSII中的获奖论文有助于 VHDL设计 Turn on some Max+Plus II Option启用选择项 There are some built-in Option to assist the engineer during the VHDL design stage一些内部选项可帮助设计 Syntax Color Option from the Option menu选择菜单中的语句颜色选择 User can modify the Color Option用户能修改颜色 use the Color Palette under Option Menu to customize the color of 在选择菜单下用调色板设定颜色 comments, illegal characters, megafunctions, macrofuncitons…. 注释,非法字符,多功能,宏功能…… Error
