An example of a simulation-only component is an ideal voltage source. There is no footprint information associated with them, and their symbols are colored black by default in the Multisim environment to easily identify them.

Simulation-only components are designed to help verify designs they are not transferred to board layout. Letters, increasing from A-Z, enumerate the devices within multi-section components. Examples of multi-section devices include logic gates or operational amplifiers. A multi-section component is a component that has multiple gates or devices per chip. Single Section versus Multi-section ComponentsĪ single-section component is any component that has a single device per chip. This footprint can be added to the Multisim database to define a custom component. This landpattern is created manually so as to precisely define the shape, size, and dimensions of a Surface Mount Device (SMD). Part 2 of the component creation articles, entitled Creating a Custom Component in NI Ultiboard, outlines how to create a custom Ultiboard landpattern for layout. Multisim also allows users to create simulation-only or layout-only components. Many components are easier to create and not all steps outlined are required under most circumstances. You will create a part with two schematic symbols, two models, but only one footprint. In the interest of completeness, you will learn how to create an advanced component with two sections. The tutorial steps you through the process of creating a simulation and PCB layout compatible component in Multisim.

Mapping the symbol pins to the model pins.

Mapping the symbol pins to the footprint pins.

Selecting and/or editing the component symbol.Selecting a footprint and the component configuration.Components details include symbol and optionally pin, model, and footprint information. The Component Wizard is the primary tool used to create custom components in Multisim, and it walks you through all of the steps required to create a new component. You will create the component and then verify its operation. The purpose of this tutorial is to explain how you can create your own components for simulation and/or Printed Circuit Board (PCB) layout from within Multisim.

This tutorial is the first in a series of articles on component creation in NI Multisim and NI Ultiboard.
