摘要

本设计有效的克服了传统的数字温度计的缺点，采用自上而下的设计思路，绘制出了系统结构流程图，最后又在硬件上通过对其进行调试和验证。基于FPGA在Quartus II13.0软件下应用Verilog HDL语言编写程序,采用ALTRA公司Cyclone- IV系列的EP4CE40F23I7 芯片进行了计算机仿真，并给出了相应的仿真结果。该电路能够实现很好的测温功能。

Abstract

This design effectively overcomes the traditional digital thermometer’s weaknesses and takes a top-down approach to design flow chart of system, and finally pass the circuits to the hardware to debug and verify it. This design is based on FPGA using Verilog HDL language to write program in Quartus II software, adopting EP4CE40F23I7 chip of Cyclone- IV series of ALTRA company for computer simulation and at the same time showing the corresponding simulation result. This circuit is able to carry out excellent temperature- measurement function.
