ABSTRACT
Digital voltmeter is a voltage measuring instruments that is referred to as DVM and it is mon in intelligent use digital measurement technology and make the continuous analog DC input voltage into discontinuous, discrete digital form and display on LED or LCD.
The design of this voltmeter main core is the Xilinx's Vritex-4FPGA voltmeter mainly divided into the following sections: data processing module is mainly depend on the TLV571 and based on this AD realizing the transforming BCD between digital measurement;dispay module realiazed the producing of the part code. The voltmeter requires the ability to display the measured voltage value in three seven-segment digital tube, retaining two significant figures after the decimal point. The software of the design is pany’s EDA development environment and using the VHDL language to write the function of the voltmeter’s each module and the program to the the FPGA board to verify the result.
