基于 FPGA 数字电压表设计
摘要: 系统基于 EDA 技术的智能数字电压表实现,以现场可编程门阵列(FPGA)为设计核心,
集成于一片 Xilinx 公司的 SpartanⅡE 系列 XC2S100E-6PQ208 芯片上,在 ISE 环境下采用超
高速硬件描述语言(VHDL)模块化编程,实现了电压的数据采集、转换、处理、显示等功能。
本设计的特点在于能够测量的电压范围宽(0~50VDC),主要采用了分压原理 ,该系统具
有集成度高、灵活性强、易于开发和维护等特点。

Abstract:The system according to the EDA technical achieve the
digital voltager,It is base on FPGA(Field Programmable Gate Array),
adopting VHDL(VHSIC Hardware Description Language) under the
under the environment of ISE.most of the designs gather in the
Spartan ⅡE series XC2S100E- 6PQ208 chip of the Xilinx company
.The whole design is composed of the data processing module, the
correspondence choice modulek, the key mold module and the A/D
convert module. It can be carry out the function such as conversion,
handle and display .It is a characteristic that is the system can be
measure the range of the voltage from 0V to 50V ,which mainly
adopting the principle in dividing voltage. The system has high
accuracy and stability,it is proved to reliable and of high value and
feasibility after testing.
