The SPICE Simulation Models page contains a list of some of the most popular semiconductor manufacturers. The best place to look for SPICE models is the manufacturer’s website. To create a simulatable component using the Component Wizard you need the component’s datasheet and a SPICE model, which is a text-based description of a circuit component. This is a component that can be simulated in Multisim to understand and predict circuit behavior. In this case, you will need the component’s datasheet to identify the pinout, select the footprint, and map the symbol pins to the footprint pins. If you only need the component for schematic capture and layout, then you can simply create a Layout-only component in the Component Wizard by defining the symbol and footprint information.
