EDA技术以EDA软件工具为开发环境，以可编程逻辑器件为实验载体，实现源代码编程和仿真功能。VHDL作为一种标准化的硬件描述语言用于描述数字系统的结构、行为、功能和接口。本设计提出了一种基于VHDL语言的编码器和译码器的实现方法。编码器与译码器是计算机电路中基本的器件，本课程设计采用EDA技术设计编码和译码器。编码器由8线-3线优先编码器作为实例代表，译码器则包含3线-8线译码器和2线-4线译码器两个实例模块组成。课程设计采用硬件描述语言VHDL把电路按模块化方式进行设计，然后进行编程、时序仿真和分析等。课程设计结构简单，使用方便，具有一定的应用价值。 (EDA technology take the EDA software as tools for the development of the environment,programmable logic devices in experimental carrier,the realiztion of the source code programming and simulation. The VHDL as a standardized hardware description language used to describe the struction of digital systems,behavior,function and interface. The paper proposes a method for encoder and decoder based on the VHDL language.Encoder and decoder is a basic computer circuit devices.This Curriculum design by EDA design encoder and decoder.Encoders from 8- 3 priority encoder for example,and decoder includes 3- 8 decoder and the 2- 4 examples of the two decoder modules.And then to program, the timing simulation and analysis.Curriculum design, simple structure, easy to use and has a value.)

介绍了基于Altera 公司的CPLD 芯片FL EX10 K,以及利用VHDL 语言实现多位二进 制码转换成8421BCD 码的原理、设计思路和软件实现。-Introduction based on Altera

频率计VHDL编程。设计一个4位数字显示的十进制频率计，其测量范围为1MHz，测量值通过4个数码管显示以8421BCD码形式输出，可通过开关实现量程控制，量程分10kHz、100kHz、1MHz三档(最大读数分别为9.999kHz、99.99kHz、999.9kHz)； 当输入信号的频率大于相应量程时，有溢出显示。 -Cymometer VHDL programming. Design of a 4-digit decimal display frequency, the measurement range of 1MHz, the measured value through the four LED 8421BCD code shows the form of output can be controlled through the switch range, range at 10kHz, 100kHz, 1MHz Three (maximum reading were 9.999kHz, 99.99kHz, 999.9kHz) when the input signal is greater than the corresponding frequency range, it shows overflow.
