Abstract
FPGA is one of the preferred device with its powerful, development process less investment, short cycle , repeated modifications, good confidential performance and intelligent development tools, and other features for today's programmable logic device design field. With FPGA design technology, FPGA hardware design is becoming increasingly clear.
The main content of this article is based on FPGA digital system design – Metro ticketing system design.The first part of article is an introduction,introduced the topic of this article the background and current situation at home and abroad.The second part is the FPGA-based design of digital systems, mainly introduces the basics of FPGA and hardware description language VHDL. The third part is the work platform MAX + plus Ⅱ software. The fourth part is a FPGA-based Metro ticketing system implementation.This section on a program statement is analyzed, and MAX + p l u s Ⅱ software compiling for simulation, Metro ticketing system functionality, and running the simulation results graph
Keywords: FPGA Metro ticketing system VHDL MAX + plus Ⅱ
