Abstract

The invention discloses a digital circuit experimental system and method. The digital circuit experimental system is provided with a core control module, a data buffer module, a liquid crystal displaymodule, a button control module, an experimental control module and a storage module. The information corresponding to all digital circuit experimental items in digital circuit experimental design teaching is pre-stored in the storage module. When conducting digital circuit experimental design, a student first generates a corresponding digital circuit on a FPGA programmable target board, and thendetermines the various functions of the digital circuit through the core control module to obtain experimental evaluation results. The digital circuit experimental system and method have the advantages that the accuracy of the experimental results of the digital circuit experimental design can be automatically determined, the judgment efficiency is improved, and teacher's work intensity is lowered.

Description

technical field [0001] The invention relates to an experiment system, in particular to a digital circuit experiment system and method. Background technique [0002] Experimental teaching is an important means to cultivate students' ability to use their own knowledge, and it is also an important way for teachers to give students guidance. Digital circuit experimental design is an important experimental course for electrical engineering students in colleges and universities. During the teaching process of digital circuit experimental design for students, students need to complete the corresponding digital circuit experimental projects in the digital circuit experimental system. The design results of experimental projects are judged. [0003] The structure of the traditional digital circuit experiment system is as follows: figure 1 As shown, including user computer, FPGA programmable target board, JTAG download / debugging circuit, input module and display module, user computer...
