Digital electronic technique network experimental platform based on Modelica

In order to solve the problems of traditional laboratory in strained equipment resources and huge invetment for updating,the Internet-based simulation and calculation were applied in experiment education and a network virtual laboratory was designed based on Modelica.The principle and process of designing a digital electronic technique network experiment platform were depicted,also its related structural topology composition was shown.The modeling and simulation of a digital circuit experiment built up with a new-type,object-oriented field unified modeling language called Modelica was introduced.The process of modeling the digital circuit decoder and the key technology of experimental scene design were elaborated,also the models were related to the front desk visualization plugin.The experiment platform was compared with EDA commercial software Multisim.The results show that the advantage of the virtual experiment platform is clear.
