NI Multisim

NI Multisim NI Multisim  (formerly  MultiSIM ) is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, along with NI Ultiboard. Multisim is one of the few circuit design programs to employ the original Berkeley SPICE based software simulation. Multisim was originally created by a company named Electronics Workbench, which is now a division of National Instruments. Multisim includes microcontroller simulation (formerly known as MultiMCU), as well as integrated import and export features to the Printed Circuit Board layout software in the suite, NI Ultiboard. Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. History Multisim was originally called  Electronics Workbench  and created by a company called Interactive Image Technologies. At the time it was mainl...

Faster Simulation with the Multisim Active Analyses

Faster Simulation with the Multisim Active Analyses Introduction Multisim now offers an active analysis toolbar. Active analyses, in conjunction with the new schematic probes, offer an easy and fast way for an engineer to run SPICE circuit simulations and quickly analyze electronic circuits to gain deeper understanding of the simulation results. Active Analysis The simulation and analysis workflow has been improved to make it more intuitive to set up and simulations and analyses.   All analyses and their settings are now accessed from the dialog box   Simulate»Analyses  and simulation   or   the new active analysis button in the  Simulation  toolbar. This button also shows the name of the active (selected) analysis.  In the example below, Interactive simulation is the active analysis:     Simply by clicking the play button, the selected analysis will start running. You will be able to visualize the simulation results e...
