Title: Design and Realization of the Digital Voltmeter Based on VHDL
Abstract: By programming the FPGA with VHDL and debugging on the EDA experimental box,basic function of the digital voltmeter is realized.Firstly,sampling control of the ADC0809 is carried out through the state machine method,then the sampled signal is converted to the BCD code.After decoding the signal is displayed by LED with three bits.The favorable ability of VHDL on circuit description and modeling is utilized in the design.Accordingly,hardware design is greatly simplified and efficiency of the scheme is improved.Because of the flexibility and expansibility of VHDL and reusing of the EDA experimental box,positivity and creativity of the students are inspired and the cost is reduced.
