Multisim Custom Simulation Analyses and Instruments Blog

Register now for TOMORROW's IEEE Webcast on power converter controllers design for smart grid with NI LabVIEW FPGA and Multisim Co-simulation tools.

Abstract:

"Just say no to trial and error when designing your next smart grid power converter or flexible AC transmission control system. Learn how to fool proof your design cycle by applying appropriate validation and control synthesis techniques. New methods will be demonstrated through the design of two FPGA-based control systems: 1. A classic field-oriented control and space-vector PWM inverter and 2. The application of set-theoretic methods in power converter controller synthesis to optimize the reliability of the closed-loop system while protecting component lifetime.  Join us for demo based introductions to the proposed techniques, including: •     New developments in set theory to automatically synthesize low complexity control laws with strong reliability guarantees, •     Power electronics co-simulation tools for automated testing of FPGA control software, •     Real-time simulators and miniature-scale grids for rapid prototyping and hardware-in-the-loop verification, and •     Deployment-ready inverter stacks and FPGA control boards for high volume commercialization."

Hello Circuit Designers,

I wanted to bring your attention to recent update!

To be able to run a LabVIEW instrument in Multisim the LabVIEW Run-time Engine (RTE) version of the instrument must be installed on your computer.

We now have different versions of the instruments uploaded to the community page.

With Multisim 12.0.1 released on September the 14th of 2012, you get the RTE2012 automatically installed and can run all the updated versions of the instruments and analyses in Multisim.

If you are a Multisim 12.0 user you only have the RTE2010 and RTE2011 installed and will have to install the 2012 one manually.

We will always keep all the instruments up-to-date and available for download.

Please let me know your feedback and if you have any questions about installing a custom LabVIEW instrument for Multisim.

Have you ever wondered how long it would take you perform a few milli-seconds transient analysis of your circuit?!

Here is an analysis tool developed in LabVIEW that ties into Multisim simulation environment and could tell you exactly at what rate your simulation is running.

Multisim 11 and 12.0 download

Multisim 12.0.1 download

Enjoy!

To properly install a custom simulation analysis or instrument in Multisim (created using LabVIEW), 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

By default, this path should be: C:\Users\Public\Documents\National Instruments\Circuit Design Suite 12.0\LVInstruments

2. Download the LabVIEW .LLB and .DLL files of the analyses (check the documents section of this community) and save them under the folder specified in Multisim Global Preferences as shown below

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