National Instruments' Multisim software provides a development environment to design, simulate and lay out an analogue or digital printed circuit board (PCB). The integrated database management system allows users to add a new Simulation Program with Integrated Circuit Emphasis simulation model to a custom assigned schematic symbol and transfer it to a chosen footprint to lay out the PCB. The Multisim Component Wizard is the main tool to create the custom parts or components of a PCB and to add the parts to the user database.
