下载后可任意编辑基于 FPGA 的数字电压表的设计 摘 要电子设计自动化(electronic design automation,EDA)是近几年迅速进展起来的将计算机软件、硬件、微电子技术交叉运用的现代电子设计技术。其中 EDA 设计语言中的 VHDL 语言是一种快速的电路设计工具，功能涵盖了电路描述、电路 综合、电路仿真等三大电路设计内容。本电压表的电路设计正是用 VHDL 语言完成的。此次设计主要应用的软件是美国 ALTERA 公司自行设计的一种 CAE 软件工具，即MAX+PLUS Ⅱ。本次所设计的电压表的测量范围是 0～5V，精度为 0.01V。此电压表的设计特点为：通过软件编程下载到硬件实现,设计周期短,开发效率高。关键词：电子设计自动化(EDA)；FPGA；VHDL；A/D 采集；数字电压表 Design of Dital Voltmeter Based on FPGAXie Xing Du(College of Zhang Jiajie, Jishou University, Jishou,Hunan 416000)AbstractThe design of digital system is becoming faster, bulkier ,smaller and lighter than before. Electronic design automation is in the last few years quickly develop, it makes use of software , hardware ,micro-electronics technology to form a course of electronic design. Among them , the VHDL language of EDA is a kind of tool of fast circuit design , the function covered the circuit describe , the circuit synthesize , the circuit imitate the true etc . The circuit of the design that use VHDL language to complete . The this time design is primarily the applied software is MAX PLUS Ⅱ which is made by the United States ALTERA company.This system’s range is -5v to +5v and precision is 0.01v.Characteristics of this electric voltage watch is :Pass the software program to download the hardware o realize , design the period is short ,development the efficiency is high.
