Hello Circuit Designers,

I wanted to let everyone know about another great project done by one of our interns from Plymouth University working at National Instruments in the UK.  myMusicalTesla takes an audio signal as the stimulus, processing this with an NI myRIO embedded controller to switch a mini-Tesla coil and using the electric field generated to illuminate an unconnected fluorescent tube in time with the music.

The myRIO controls everything in this project - it takes audio input from its built-in audio jack, samples this data and performs an FFT on the onboard FPGA. Finally, it switches the Tesla Coil 100,000s of times a second in order to resonant the circuit. As well, another DIO line is used to pulse the circuit at the frequency of the note you wish to play. Everything is programmed in LabVIEW allowing quick coding and interfacing with the circuit board efficiently and easily.

After designing the circuit in Multisim, the resulting design was transferred it to Ultiboard for PCB layout. To check out the full project with schematics, PCB layout and code visit this location.

Hello Circuit Designers,

I wanted to let everyone know about some great work done by one of our interns from the University of Manchester working at National Instruments in the UK.  myBall & Beam is based on the classic ball balancing systems control using myRIO as the controller, Multisim for schematic design and Ultiboard for PCB layout.

ball and beam.jpg

myBall & Beam uses an IR sensor to continuously detect the ball's current position and a servo to control the tilt of the beam. This information is analyzed on the myRIO's embedded processor to provide feedback to the system. To check out the full project with schematics, PCB layout and code visit this location.

Hello Circuit Designers,

I wanted to share some exciting news about Multisim making the list of EDN Hot 100 Products of 2014 not once but twice.  Of the seven EDA tools that made the list Multisim Touch for iPad and Multisim Blue both made the list.

EDN100.jpg

Multisim Touch for iPad was released to the iTunes store in June and brings the intuitive Multisim SPICE simulation environment to the iPad. Multisim BLUE is a collaboration between National Instruments and Mouser Electronics. A key feature is the Mouser database, which is updated by Mouser Electronics, and provides a broad variety of up-to-date components from leading component manufacturers.

I can hardly wait to see what’s in store for 2015.

The latest upgrade to Multisim Touch includes interactive power source.  These are very useful.  Now have the ability to vary amplitude and frequency.  Issue is that this is not available in Multisim 13.  Are there any plans of having the same interactive sources for Multisim 13?

Not all SPICE models are created equal.

This saying applies especially to a model’s dependence on temperature.

Multisim allows the user to set the operating temperature of the simulation (the default is 27°C).  Using the Temperature Sweep analysis, Multisim even allows the user to sweep across a range of temperature values, running an underlying simulation such as DC operating point or Transient  for each step in the sweep.  However performing such an operation only makes sense if the models of the critical components in your circuit are designed to support temperature variation.

Let’s consider two BJTs with Model A and Model B.

Transistors.png

Let’s configure Temperature Sweep analysis to run a sweep from -55°C to 125°C and monitor the effect on beta, which we setup using an expression with the format I(ProbeN)/I(IbN) in accordance with the above naming of the probes and current sources.

TempAnalysis.png

The following is the result for Model A:

ModelAResult.png

This beta variation with temperature matches the part’s datasheet reasonably well.

The following is a result for Model B:

ModelBResult.png

This result does not match the part’s datasheet, which shows a much greater variation in Beta. In this case, it can be concluded that the model does not support temperature variation.

Notice that a model’s lack of support for temperature variation does not necessary imply that the results produced by the model will not vary with temperature. Clearly, as shown by model B, the temperature may play a role in shaping the model’s curves. A model’s lack of temperature support implies that simulating the model using a temperature different from which it was designed for will likely lead to incorrect results.  Models that do not support temperature variation are typically designed for 27°C, the default setting in Multisim.

Therefore, it is good practice to run a simple, isolated test on the model and compare the results against expectations before assuming the model supports temperature variation and using the model in circuit-wide temperature analysis.

Hello Circuit Designers,

I found another interesting white paper in the series on using simulation in the design flow that I wanted to share. In this case an EPC eGaN FET is used in various power conversion topologies utilizing models developed in collaboration with National Instruments and EPC. Although quantum-based effects are not incorporated, the models accurately reproduce the basic response of the devices under circuit operation conditions.

buck-boost topology.jpg

For more details on simulating with the EPC eGaN FET you should check out Design Efficient Fast Switching Power Converters with EPC eGaN FETs in our white papers. This paper demonstrates how Multisim best-in-class simulation can be used to enable accurate evaluation of overshoots, efficiency and power dissipation in switch-mode power supplies resulting in a more efficient design process.

Hello Circuit Designers,

As a circuit designer you rely on datasheets to define the specification of your design. Although they are an indispensable resource datasheets often lack detailed information on how parts will behave in different configurations.  Using Multisim SPICE simulation in the design flow can provide valuable insight into component behavior and reduce iterations.

For an interesting example on how simulation can be used in this manner you should check out Accurate Switched-Mode Power Supply Designs with NXP Components in our white papers. This paper, on the power stage of a DC-to-DC buck converter, uses Multisim SPICE simulation to determine how LC values effect ripple, the efficiency of the converter as well as using power dissipation to better understand thermal behavior.

Hello Circuit Designers,

I found an interesting article on using noise analysis which I would like to share. The article provides step-by-step details using an Analog Devices operational amplifier to demonstrate the benefits of using advanced analyses in your designs.

Noise analysis is a small signal analysis which is carried out at discrete frequencies using a linearized version of the circuit. In essence invisible noise sources are attached to every noise-generating element in the circuit and the analysis is performed against a reference voltage or current.

Noise Plot.jpg

Here is the complete noise analysis tutorial  that demonstrates in detail how to calculate total noise values, power spectral density curves and the model requirements when performing noise analysis.

Hello Circuit Designers,

How do you use Multisim in your workplace? I recently came across an interesting whitepaper on using Multisim, LabVIEW and PXI to verify the design of flight and optical electronics for a satellite system that I wanted to share with the community.

Design Flow.jpg

Due to the harsh conditions, i.e. outer space, in which the satellite would be operating the accuracy of this design was of utmost importance. There were three stages to the design flow:

  1. The design was captured and simulated in Multisim and presented to management for approval.
  2. The approved design was validated with LabVIEW and  Multisim
  3. The completed design was handed off to a layout team to build a prototype for further design validation

The final design prototype was connected to the PXI hardware. LabVIEW SignalExpress was used to acquire these real measurements. With real measurements being acquired through LabVIEW SignalExpress, and with the transfer of simulated data, we can correlate both sets of data. By viewing the differences between the data, the process of benchmarking and validating performance is easily done.

For the complete whitepaper on using Multisim, LabVIEW and PXI to effectively prototype a design see Flight and Camera Electronics for a Satellite System – A NI Multisim National Lab Application. For other interesting case studies and whitepapers on using Multisim in industry visit this location.

Hello Circuit Designers,

Multisim was presented as part of the Hybrid Automotive HIL (Hardware-in-the-loop) presentation on Day 2.  It briefly demonstrates downloading a SPICE simulation to an FPGA, and then using the FPGA solver to run the simulation. With this feature you export the matrix for a subset of specialized models and use this matrix to simulate the circuit on an FPGA using Hardware-in-the-loop simulation which greatly speeds up verification of designs. The supported models include the ideal switch, diodes, capacitors, inductors, transformers and resistors. Essentially a lot of the elements that go into switch mode power designs which is what this will initially be used for.

You can watch the entire Day 2 keynote presentations here or skip forward 52 minutes to see the Multisim presentation. If you are interested there is an NI Labs paper with complete details on this new feature coming soon.

Lastly, if you want to know more about NIWeek I would encourage you to check out some of the other cool/interesting videos on the National Instruments YouTube channel.

Hello Circuit Designers,

 

Today I want to highlight a relatively new Multisim feature using interactive simulation that you may not know of. A virtual instrument created in LabVIEW can be used to connect real-world signals to Multisim or output simulation data to drive real-world circuitry. You can build either an input instrument where Multisim inputs data to a LabVIEW instrument or an output instrument in which LabVIEW outputs data to Multisim.

 

LabView VI in Multisim.jpg

 

A LabVIEW input instrument continuously receives data from Multisim while the simulation is running. You can then connect simulation results to real-world I/O such as DAQ, GPIB, Serial, File, and the like. A LabVIEW output instrument uses data that is acquired beforehand which is then used when the simulation is running. This means that data acquisition has to take place before you start a SPICE simulation (for example, first record data with the microphone and then start the simulation).

 

To create a LabVIEW virtual instrument for use in Multisim you use LabVIEW to create a Front Panel with the appropriate controls, coding and save as a custom instrument. Then, using Multisim you place the new custom instrument on your schematic, connect the terminals and run your simulation.

 

In order to simulate with a custom LabVIEW instrument you will require Multisim version 12.0 or later and LabVIEW 8.x or later to create the virtual instruments that you will use. You only need LabVIEW to create the instrument. LabVIEW does not need to be installed on the machine where you intend to run Multisim. 

 

Let me know if you have any feedback or questions on this or any other Multisim topics.

Hello Circuit Designers,

One thing I recently noticed is that there are a lot of Multisim resources out there but they’re not always that easy to find. I thought it would be useful to point out some of them today. To begin with here is the National Instruments landing page for Multisim. It has the usual wealth of product information but for our purposes we will explore some of the other Multisim resources that are available from this and other locations on ni.com.

MSM-puzzle.jpg

The introductory page NI Multisim and Ultiboard Technical Resources has getting started tutorials on Multisim and Ultiboard, how to get technical support as well as more advanced discussions such as SPICE simulation fundamentals and PCB layout best practices.

If you are looking for concepts, circuits and simulations you should visit the National Instruments Circuit Design Technical Library. This is a fairly comprehensive source for schematic design, SPICE simulation concepts and advanced simulation discussions including incorporating LabVIEW measurements into Multisim. As well you will find a good collection videos of NI Multisim Technical Help Videos available.

For in depth discussions on Multisim, Ultiboard and NI ELVIS check out the White Papers section. This area is updated often so you should check back frequently. A quick search on the term Multisim turns up almost 400 hits with topics such as detailed application notes, integrating Multisim and NI ELVIS, as well as a plethora of courseware. More Multisim courseware, broken down by year of study and application, can also be found here.

National Instruments maintains two Multisim specific communities National Instruments Circuit Design Community (this location) and Multisim Custom Simulation Analyses and Instruments. The latter location has a large set of custom instruments and analyses for use in Multisim that were developed in LabVIEW and are geared towards specific engineering applications such as system control, audio signal processing, noise analysis, and power design.

I hope this quick overview has provided you with a good basis for your exploration of circuit design and simulation with Multisim. Let me know if you have some favorite sources for circuits, models or other Multisim resources that you would like to share.

If you haven’t heard Multisim Touch for iPad is the newest edition to the Multisim lineup that provides engineers, educators and students a platform to design and simulate analog circuits anywhere. This circuit design app allows users to quickly build circuits with a library of common devices and visualize the performance in an interactive graphical environment. Over the past few weeks we’ve had a good response with many positive comments worldwide.

  Touch Circuits.jpgToday I wanted to share some additional resources for getting started as well as some interesting courseware. This location is the starting point for all things Multisim mobile. If you scroll down the page to the Technical Resources section there are many videos and circuit examples for use with Multisim Touch for iPad. For example, the Getting Started videos cover the basics from building a design to simulating and analyzing a circuit. You can download the Getting Started Circuits directly to the iPad and begin simulating right away.

Multisim Touch for iPad is part of the NI Circuits Teaching Solution which provides an integrated environment for simulation and circuit design across tablets, desktops and teaching hardware. The Multisim Touch Courseware Examples section of the Technical Resources page contains over 30 circuits for first and second year analog circuits courses. These circuits are based on existing Multisim courseware and provide a great starting point for creating, simulating and analyzing circuits on Multisim Touch.

Please let me know if you have any feedback or questions on this or other Multisim topics, or on how you plan to use Multisim Touch in your classroom.
