Automatic Construction and Verification of Simulation Model of Electronic Equipment

In the structural design and performance simulation of electronic equipment, there are some problems, such as low efficiency of modeling, low accuracy of simulation model, insufficient accumulation and reuse of simulation knowledge etc. An automatic building platform for simulation model is developed based on the commercial simulation software. By feature recognition and simplification, technology of automatic model building and component database integrated management of printed circuit board, etc., this platform has realized automatic modeling of CAD/CAE simulation model. Dynamics and heat dissipation analysis for typical electronic equipment are carried out for verification. The results show that the platform can obviously improve the modeling efficiency and correctness and simulation accuracy of the simulation model for complex electronic equipment.
