A circuit simulation experimental system based on re-development SPICE

A novel scheme that uses the Simulation Program with Integrated Circuit Emphasis (SPICE) simulation program as a behavioral macromodeling language in designing circuit simulation software 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 ActiveX components, which succeeds in solving integration of simulation technology and multimedia technology. In the paper, an application example is also given. Test results and application 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.
