Design and Implementation of Multi-Channel Responder Based on FPGA

A multi-channel contest device is designed and implemented using VHDL language and graphic editor as input style based on software platform of MAX+PLUS lI.Each functional module and circuit diagram is presented in this paper,by editing,compiling,simulating and device programming,files are downloaded to the device of EPF10K10 series of LC84-4 chip for testing.The results show that the system can not only realize to lock with each other and itself,display the number of the first player correctly,but also limit the answer time for 30 seconds of the alarm and reset the responder.
