Designing Digital-Calculagraph By Verilog HDL

The paper introduces a design project of Digital\|Calculagraph by Verilog HDL. Using the Hardware Description language to design Digital\|Calculagraph has advantages such as low cost, simply to design, easy to expand. It analyzes the total configuration of the system, gives the HDL description of each part of logic electric circuits and the synthetical result of the electric circuit.
