Design of Taxi Accounting System Based on Verilog HDL
Abstract: This paper studies using Verilog HDL language to realize the taxi accounting system. The design about the taxi accounting system based on the current situation of taxi accounting the city's investigation and analysis, and thinking about the implementation method of the Verilog. In order to let the taxi accounting system with the required Verilog HDL better integration, through research and experiment, the taxi accounting system more reliability and practicability, the design and testing, the design and implementation of some related function taxi accounting system, including the timedisplay, accounting and simulate the taxi start, stop the reset function, etc.This design uses the modular design, mainly includes display module, timing module, accounting module and the counting module, through the combination of these functions and modules, to complete the taxi accounting system hardware circuit design and simulation results, to achieve the desired results.
