Abstract :
A method for modeling analog circuits at the behavioral level using nonlinear differential equations is described. The resulting models execute efficiently in various simulation environments, including a circuit analysis program and an event-driven logic simulator. Behavioral models are expressed as differential equations with respect to time. A variety of linear and nonlinear operators are provided. The equations provide a concise method of specifying circuit behavior in engineering terms, rather than in programming terms. The equation compiler produces three object models from a single equation source model. One of the object models is used by a circuit simulator, ASTAP, the second by DSL, a continuous system simulation language, and the third by an event-driven logic simulator. The compiler and its run-time libraries guarantee that all of the object models perform identically
