This tutorial provides instructions on how to properly setup custom simulation analyses created in LabVIEW into the Multisim environment.

Set Up your Custom Analysis

Multisim 12.0 supports custom analyses created in LabVIEW 2010 (and previous).
 

Multisim 12.0 features eight different built-in tools for custom analyses; users can include an unlimited number of analyses to fit their simulation needs. The following table lists the built-in analyses and examples of circuits users can evaluate.
 

Analysis Tool

Circuit Example

NI PXI-655x Waveform Generator

Modeling of NI PXI-655x waveform generator connectivity to ECL and TTL circuits

BJT Analyzer

Characterization of transistor SPICE models

Impedance Meter

Matching, complex I/O impedance, reflection of reactive circuits of high-frequency circuits

Microphone and Speaker

Signal processing of audio signals

Signal Analyzer

Gilbert cell mixer at IF stages

Signal and Streaming Generators

Binary weighted input digital-to-analog converter


In addition to the simulation analyses you automatically receive when installing the software, NI has provided more custom analyses to download and include in your simulation. Click here to download these custom analyses.
 

To properly install these analyses, follow the below steps:
 

  1. Open Multisim and check the default location for the User LabVIEW instruments path under Options»Global Preferences as shown below.
     


 

  1. Download the LabVIEW .LLB and .DLL files of the analyses (download table here) and save them under the folder specified in Multisim Global Preferences as shown below.
     


 

  1. Restart Multisim, and these tools should appear in the Instruments toolbar under LabVIEW Instruments as illustrated below.
