Title: A Circuit Simulation System Based on SPICE Secondary Development
Abstract: A novel scheme that uses the SPICE (Simulation Program with Integrated Circuit Emphasis) simulation program as a behavioral modeling language in designing the simulation system of electronic circuit experiment is presented. In the proposed method, SPICE, being redeveloped by transformation and expansion, is used for simulating model and imbedded in the multimedia interface with DLL (dynamic link libraries) files, which succeeds in solving integration of simulation technology and multimedia technology. In the paper, an application example is also given. Test results show that the system achieves excellent performance in designability, arbitrariness of operation and interaction with sense of reality, which makes users operate it with great interest just like doing real experiments and gains good effect in experimental teaching.
