【正文】 al logic circuit using Simulink model, and pares the experimental waveform of simulation circuits to actual theoretic logic functions, thus makes learners learn and understand their basic principles well.The simulation results indicate that designing and testing digital circuit with Matlab make the results visual, time saving and effortsaving. It can be used not only to simulate the circuit what mentioned in this paper, but also widely used in other digital circuit simulation. Matlab is an effective tool for debugging and designing digital circuit.Key words:digital logic circuit。flipflop。counterXXXX 大學(xué)畢業(yè)設(shè)計(jì)（論文）III目 錄引 言
