DesignCon 2012 - Whitepaper Presentation: An Improved Approach to Prototyping ...

[Bhavesh]

Hello All!

The National Instruments Toronto team were excited this year to be able to present an all new paper at DesignCon 2012 entitled "An Improved Co-Simulation Approach to Rapidly Prototype, Verify and Implement Dynamic FPGA-based Embedded Control Systems". The paper was written by two of our simulation engineers here on our R&D team (Oleg and Muris).

Before the session this morning, we were informed that the paper had been nominated as one of the best papers of the conference (a huge honour for the NI Toronto team!) Attendees were impressed by the all new concepts discussed in the paper and an all new approach to analog and digital design is being considered by a new group of engineers here in North California.

The official DesignCon session description:

This session presents a new co-simulation methodology for the rapid prototyping, design, and verification of digital controllers for switching power electronics circuits. A case study of a closed-loop DC motor drive, comprising of a digital controller and analog drive circuitry, is used to illustrate the new method. Using an NI Multisim SPICE simulation plug-in for the LabVIEW simulation module the complete system was verified and optimized using transient simulation prior to being implemented in hardware. All digital FPGA elements were modeled in a graphical system design/programming environment, while the analog power stage was modeled with SPICE. The system simulation results were compared to the experimental measurements. It was found that the measured motor speed and the DC motor armature current closely matched the simulated results, supporting the method of co-simulation as a valuable, insightful and productivity enhancing initial step prior to system implementation.

Interested? But you were unable to attend the show this year? Well we have put the slides up online to share with you. Just click on the PDF below.

There will be more content coming live about co-simulation etc... over the next few weeks, so be ready to learn more! Need to contact someone about it? Message mahmoud.wahby@ni.com.
