SimElectronics provides libraries of semiconductors, integrated circuits (behavioral models), and passive devices. You can connect transistors, diodes, op-amps, and other components to model electronic systems. The models you create can be grouped into subsystems, letting you build reusable libraries of circuit components. Connecting these electronic systems with control systems modeled in Simulink enables you to combine digital control with behavioral models of analog circuits.
In addition to the traditional input-output or signal flow connections used in Simulink, the electronic component models in SimElectronics use physical connections that permit the flow of power in any direction. Models of electronic systems built using physical connections closely resemble the electronic circuit they represent and are easier to understand and share.
The transistor models in SimElectronics include nonlinearities and high-frequency dynamics to help you capture these effects in simulation. Many components in SimElectronics enable you to specify temperature-dependent behavior and configure a thermal connection to model the heat transfer within your system.
To help you specify realistic parameter values, various parameterization methods are provided for many components. You can read parameter values directly from data sheets or assign the equation parameters.
