  <md:abstract xmlns:bib="http://bibtexml.sf.net/">This module provides an exercise with step by step instructions for instrumenting simulated circuits in National Instruments Multisim.  Multisim is fully featured SPICE schematic capture and simulation tool used for circuit design, simulation, and in combination with Ultiboard for layout of custom PCBs.</md:abstract>
