Issue Details

I am building a circuit in Multisim and cannot find a component in the Master Database. Where can I find new components or libraries for Multisim?

Solution

A large number of components can be found in the Multisim Master Database. If the required component is not found the user must make a custom component using the Component Wizard in Multisim:
  • Select Tools >> Component Wizard
  • Determine whether you need a Layout-only or a Simulatable component
  • Use the step-by-step instructions in the Component Wizard. Refer to Creating a Custom Component in NI Multisim for additional information

Additional Information

Layout-only component

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. 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.

Simulatable component

This is a component that can be simulated in Multisim to understand and predict circuit behavior. 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. The best place to look for SPICE models is the manufacturer’s website. The SPICE Simulation Models page contains a list of some of the most popular semiconductor manufacturers. 

If you are not able to find a SPICE model to simulate an IC component you can look for the SPICE model of a similar or a cross-reference part (i.e. another manufacturer) or alternatively, create a SPICE macro model by using the equivalent circuit of the IC. Refer to Creating a SPICE Model From a Macro Model Circuit Schematic in Multisim.
