  Hi Anastvl,

  Your mapping of the model was not properly Setup.  The next section of the model is very important, he says the model and order pins, you need this information to properly table parameter mapping in Multisim.  The first pin reported in this model is not inverseuse entry, second pin said entry.. inversion last pin was released.  The key is to watch the line model subckt and to know the order that the pins are reported.

  Hello

  I wrote my description of the error also here: http://forums.ni.com/ni/board/message?board.id=280&message.id=5055&jump=true#M5055

  When using "run vi on the development computer" I get an error broken pointing me to the "open FPGA vi function", the problem

• FPGA/FlexRIO error-61046

  Hi all

  Please, for the love of God can someone take a look at the attached FPGA project, I hit to the top and tell my why it is that whenever I run, as soon as he's trying to read/write on the host computer, it returns error-61046? A screenshot of the error is included in the attached .zip file.

  I made many programs FPGA before with no problems, while using the same FPGA and FlexRIO module and never had this problem. If I run an example program it works fine so I am confident, that the error lies in my programming, I can just see where!

  As you can see all the clocks are internal and appear to be configured correctly according to the example programs and other programs FPGA, that I have done before, so I'm puzzled. I hope that it is just my stupidity and lack of coffee.

  Congratulations in advance.

  The pilot FlexRIO comes two CLIPs for the 5781. At ' a "NI 5781 Sychronous system" OR 5781 "VIDEO CLIP.

  The "NEITHER 5781' is what originally delivered with the FAM and is always delivered with the driver for legacy purposes. I would discourage the use of this CLIP because it uses regional clocks for IO Module clock 0/1 which limit the amount of fabric that can be driven by these clocks to the fabric available in the respective region of the FPGA. The advantage of this CLIP, it's that the ADC and DAC can be clocked at different rates through a clock divider that exposes the CLIP.

  The 'NI 5781 Sychronous system"CLIP is what is recommended for all new models. It uses a world clock which can target tissue in all regions of the FPGA. This CLIP uses the same clock to drive the ADC and DAC (IO Module clock 0). IO Module clock 1 is not used in this CLIP.

  If you used the sychronous CLIP system and always a logic had driven out by IO Module clock 1 it that would explain why you received the error of non-response from IO Module clock 1 is left connected in the sychornous CLIP system.

• Led Simulation error

  I had problems with a more complex circuit that I played with, and I've narrowed the problem down to handling of Multisim diodes during the simulation.

  The circuit below shows two branches that have identical resistances but there is a diode in series with it if she performs only other each half cycle. It is a rectifier and theory tells us to wait for the RMS current through resistance to 70.7% of the current flowing through a resistance that does not have the diode in series (for an ideal diode). For R2 below I (R2) = 12/2.88 = 4 .16A and this is properly determined by XMM2 multimeter. The current in the branch of the diode must be 4.16 * 0.707 = 2.94 A but as you can see XMM1 multimeter is far away. I changed the led a virtual model and the current has dropped to 2.14 A...

  

  I checked this with the same values of resistance and the diode model using LTSpice and I get the correct results with this program (which allows Fior diode charactersists)...

  

  I have attached two files (Multisim 14 and LTSpice) simulaiton for reference.

  So what is happening here?

  Hi Myamigo

  Thanks for that information, I think that the issue here is with the multimeter and not with the circuit. I used a current probe and got A 2.8 on this line. I enclose a picture showing this.

  I think that this may be due to a configuration on this unit or it can also be a CAR, but I need to conduct additional research on this to see if it is a wrongful conduct of Multisim multimeter.

• tables of fixed size in FPGA compilation error - how to implement a waveform control in an FPGA?

  Hello

  After being stuck for two days, please let me briefly describe my project and the problem:

  I want to use the cRIO FPGA for iterative control of waveforms. I want to capture a full period of the waveform, subtracting a reference waveform period and apply control algorithms on this. Subsequently the new period of correction must be sent again for the output module OR. If it does not work, the captured waveform will look like the one reference after several iterations.

  I am planing to create an array of size fixed for the capture and the reference waveform (each around 2,000 items for a given period). I use so 2 paintings of each elements of 2000. I use the function 'replace the subset of table' to update each element captured in the loop sampling and a feedback for each table node to keep in memory (I also tried shift registers, but then the berries do not have a fixed size any more and I can't start the compilation process).

  If I try to compile the FPGA vi, I get the following error:

  Details:

  "Synthesize - XST" process failed

  Before I added berries to my code I could compile the FPGA without problems. So, it seems that the tables are too big for the FPGA. :-(

  Therefore, I would like to ask if there is perhaps a better method to implement my problem in LabVIEW FPGA? How could avoid the tables to save my waveforms on a period?

  Thanks a lot for your help in advance.

  Best regards

  Andreas

  Unfortunately, the LabVIEW FPGA compiler cannot deduct stores shipped from berries (yet). When you create these two large paintings, you are creating essentially several registers very, very large. Just by looking at your picture, I guess that there are at least 4 copies of each of the tables.

  You want to use LabVIEW FPGA memories instead. You can create memories outside the loop and then read/write them where you are currently referencing the berries. The only change that you really need to do is to break down your treatment in scalar operations. I have attached a simplified version of your plan, I hope it helps. Let us know if you have any other questions.

  

• Compilation of FPGA 61330 error on a cRIO

  Hi all

  Currently, I have to rebuild a fpga bitfile to reflect a new hardware configuration on a cRIO. I have installed on my computer, tools that have been able to compile the bitfile several times; but now I get an error when I compile. I have attached two images of the error to this message. I'm currently under this software configuration:

  It turns out it was a firewall issue. I had turned off my firewall, but there was a tertiary process still running. I added a few my firewall exceptions, which should allow the program to work, but it didn't. Once I deleted these exceptions, the compiler run with no errors. I think it's time to get a new firewall program. Thanks for all your help.

• FPGA compilation error

  I'm converting a piece of code from 8.5 to 2011.  When I tried to compile the fpga vi to a bit file, I get the error attached.  Why is this?  Thank you!

  The thing is that the only solution that I found about this error is to install a patch or repair/reinstall Xilinx or LabVIEW FPGA tools.

• FPGA compilation error sbRIO 9632

  Hi guys,.

  I'm trying to write a simple piece of code to send a PWM signal to a PIN on my sbRIO-9632 (starter kit 2.0) to order a servo. I used the example of 'control a servo using PWM' and my code is pretty much the same. When I try to generate/compile the FPGA VI, it stops after only 4 to 6 minutes, saying an error has occurred. The compilation appears to hang during the process of the "card".

  The example is for a sbRIO-9631 so I created a new project for my robot Robotics and changed the PIN e/s that I use (Port5/DIO9). I search through forums but cannot find a solution to this :/

  I have attached my code and the XilinxLog file with it.

  Thanks for any help!

  Hello

  Sorry for the late reply! Have you made progress?

  Unfortunately, your zip file seems to be disabled on my PC. How it has been compressed?

  So what I meant by remove the digital Pulse.vi to generate, is to see if it affected the compilation. Please see if you can compile the FPGA code with the following approach:

  Create the new project > add your target sbRIO > add the VI attached to this post to your FPGA target > compile

  I think it would be beneficial to you to see if the problem is the compilation itself or the code you are trying to compile.

  In addition, you have any another available PC? Might be a good idea to see if your code compiles on another PC.

  Please make sure you have LabVIEW Real-time and LabVIEW FPGA installed (it should come with the Robotics module, but I recommend that you check that they have indeed been included).

  If the build process fails to map no matter what you do, I propose the following: make sure that the target passes a self-test of MAX. reinstall the Xilinx tools (only if it seems that the issue is not with the code, but with the compilation process itself).

  Good luck

  Best regards

• How to manage the turnover in number of cycles of FPGA output?

  I wrote a little VI that counts ticks on a set of lines of DI for a period of time. It uses the number of cycles of VI to determine how much time has passed since he started running. The output of this VI is a U32, and subtraction function looks like it going to saturate to '0' if the number of cycles longer rolls. How can I handle this situation to prevent the VI to leave earlier?

  

  Integer arithmetic must manage calculation rolling correctly (for example if your value is a U8 and you do 3-250, you should get 9). I guess (although I never checked) it works even in the FPGA. You can do a simple check yourself with explicit code. It would be nothing less than a complete cycle of safe, so it depends how much time it takes. If it is ms, it would take about 50 days. In your case, it seems that you have configured the service to be in us, so it would be somewhere more than an hour. If that's not enough, then you can maintain the real value in a U64 and then take the number of us that passing in each iteration and that adds to the U64.

• DMA FIFO of FPGA compilation error

  Hello

  I have a cRIO 9074 with FPGA. I tried a simple piece of code to learn how to acquire the data that is generated on the FPGA at a rate of 10 KHz and transfer it to the host VI to treat later in offline mode.

  Hi Rick,

  Given that the CD does not work in Windows XP computer also, there seems to be a problem with the drive itself.

  Clean the CD or the DVD. To do this, use a disc cleaning kit. Or gently wipe the silver part of the disc with a soft and Lint cotton cloth.

• JDE Simulator error "reload software: 552".

  Hi, I use Blackberry JDE version 4.7 with Simulator 4.6.0.150 bold 9000. Everything works fine an hour ago.

  It just started to show "reload software: 552" all of a sudden. He have no importance how to start the simulater, JDE debuger, or simply run the Simulator booth along.

  There is a solution to a real device for this error message, but what it means for a Simulator?

  Thanks for your help.

  Chimera

  If you run your 4.7 on a "BOLD" device software, you run the risk of "bricking" of the device, then do not.

  The JDE 4.7 has only a simulator of the storm, because the storm is the only device which manages 4.7 OS.

  If you want to target the "BOLD", then use the 4.6 JDE or more LOW (no more).
