Digital circuit experiment system based on FPGA

Traditional digital circuit equipments have some deficiencies, such as limited functionality, fixed experiment types, needing complex wire connection operation, only dealing with simple experiment and so on. The paper presents a FPGA-based digital circuit experiment system that provides a rich set of peripheral interfaces and design resources, and on the system function implementation and function verification of various digital circuit designs can be easily realized aided by EDA software. The paper provides experiment operation method and three-stage experiment training method on the system, and it shows the system supports most traditional experiments, but can realizes most of the functions the traditional ones cannot realize, meanwhile gives a flexible and high efficiency design pattern.
