Simulating Analog Circuits … The Analog Devices Way

This is a quick article about a simulation tool available for analog simulation.  In this article, we are going to focus on MultiSim SPICE which was developed by NI for Analog Devices.  You can download it free of charge off of the Analog Devices website (MultiSim).

I recently had to design an amplifier for a load cell.  I came across the MultiSim design tool.  I was able to use real analog devices parts and simulate them with all the accuracy I needed.  The only limitation is that you can only have 25 parts which is a bit of a downer.  However, most analog circuits have less than 25 parts.  They also provide libraries for their voltage references and the rest of the line.  I will post another article on designing an amp circuit for a load cell.
