Abstract: Circuit simulation is becoming an essential technique for circuit designers to verify and check their designs of electrical and electronic circuits and systems before their deployment and fabrication, which has been one of the most important EDA tools. The analysis of nonlinear circuits always needs to solve a system of nonlinear algebraic equations or differential equations. This talk will show several promising methods of solving nonlinear DC circuits from both theoretical viewpoint and practical viewpoint. Several methods are implemented on our SPICE simulator - WSPICE, and they have been applied to the practical large-scale analog circuits to verify the effectiveness in commercial circuit simulation software. In addition, challenges of solving nonlinear DC circuit equations will also be addressed. And several mathematical problems and challenges still to be solved in transistor-level circuit simulation will also be introduced briefly.
