LabVIEW FPGA CLIP node compilation error
I work on an application for my Single-Board RIO (sbRIO-9601) and faced with a compile error when I try to compile my FPGA personality via the ELEMENT node. I have two .vhd files that I declare in my .xml file and all at this point works great. I add the IP-level component to my project and then drag it to the VI I created under my FPGA.
Within the FPGA personality, I essentially have to add some constants on the indicators and entries CLIP to my CLIP out and attempt to save/compile. With this simple configuration, I met a compilation error (ERROR: MapLib:820 - symbol LUT4... see report filling for details on which signals were cut). If I go back to my VI and delete indicators on the output (making the output pin of the CLIP connected to nothing), compiles fine.
I've included screenshots, VHDL and LV project files. What could be causing an indicator of the output of my VI to force compilation errors?
Otherwise that it is attached to the output ELEMENT, a successful compilation...
After that the output indicator comes with CLIP, compilation to fail...
Windows XP (32-bit, English)
No conflicting background process (not Google desktop, etc.).
Usually a "trimming" error gives to think that there are a few missing IP. Often, a CLIP source file is missing or the path specified in the XML file is incorrect.
In your case I believe that there is an error in the XML declaration:
This indicates LV FPGA to expect a higher level entity called "RandomNumberGenerator" defined in one of two VHDL files. However, I couldn't see this entity in one of two files. If urng_n11213_w36dp_t4_p89 is the top-level entity, edit the XML to instead set the HDLName tag as follows: Also - in your XML, you set the 'oBits' music VIDEO for output as a U32, however the VHDL port is defined as a vector of bits 89: oBits: out std_logic_vector (89-1 downto 0) These definitions must match and the maximum size of the vector CLIP IO is 32, so you have to break your oBits in three exits U32 output. I have added the ports and changed your logic of assignment as follows: oBits1(31 downto 0)<= srcs(31="" downto="">=> Both of these changes resulted in a successful compilation. Note: The only compiler errors when you add the flag because otherwise your CUTTING code is optimized design. If the IP is instantiated in a design, but nothing is connected to its output, it consumes all logic? Most of the time the FPGA compiler is smart enough to get it out.
oBits2(31 downto 0)<= srcs(63="" downto="">=>
oBits3(31 downto 0)<= "0000000"="" &="" srcs(88="" downto="">=>

Note Labview 2012 SP1 installed about 2 weeks ago.,.
Accident occurred during the compilation of an fpga vi who worked satisfactorally in the past.
When I restarted and went to the message recomplile "LabVIEW FPGA: an internal software error in the LabVIEW FPGA Module" see attached picture of popup.
I reinstalled Labview in its entirety and backed out the changes I made to the vi but still get the same message.
Thanks in advance
It turns out that the question was in the VI and not of LabView FPGA module as the message may indicate. I created a vacuum vi, cut and pasted items in this from the vi error and recompiled and it ran very well.
Somehow the vi has been corrupted internally.
Thank you it's fixed.
I'm having some difficulties to understand how the clock is part of the node IP for LabVIEW FPGA and was hoping to get some advice.
What I try to do is to set up a digital logic circuit with a MUX feeding a parallel 8-bit shift register. I created the schema for this Xilinx ISE 12.4, put in place and can't seem to import the HDL code into an intellectual property node. When I run the VI, I am able to choose between the two entries for the MUX, load the output in the shift register, clearly the shift register and activate the CE.
My problem is that when I switch to the entrance of THIS, he should start 1 sec shift (Boolean true, SCR, High, what-have-you) in the registry once each clock period. Unfortunately, it instantly makes all 8 bits 1 s. I suspect it's a question of clock and here are some of the things I've tried:
-Specify the input clock while going through the process of configuring IP nodes.
-Adding an FPGA clock Constant as the timed loop.
-Remove the timed loop and just specifying the clock input (I'm not able to run the VI that I get an error that calls for a timed loop)
-Do not specify the clock to enter the Configuration of the IP node and wiring of the FPGA clock Constant to the clock input (I can't because the entry is generated as a Boolean).
-Remove an earlier version of the EC who had two entries up to a door and at ISE.
-Specify the CE in the process Configuration of the IP nodes.
-Not specify this in the process of setting up nodes IP and wiring it sperately.
-Various reconfigurations of the same thing that I don't remember.
I think I'm doing something wrong with the clock, and that's the problem I have. Previously, when I asked questions to the Board of Directors on the importation of ISE code in LabVIEW FPGA, a clock signal is not necessary and they advised me to just use a timed loop. Now, I need to use it but am unable to find an explanation online, as it is a node of intellectual property.
Any advice would be greatly appreciated, I'm working on a project that will require an understanding how to operate clocks the crux of intellectual property.
Thanks in advance,
P.S. I have attached my schematic ISE and the LabVIEW project with one of the incarnations of the VI. The site allow me to add as an attachment .vhd file, but if it would help I could just paste the body of the code VDHL so just let me know.
I spoke to the engineer OR this topic and it seems that it was sufficient to verify that your code works, by putting a wait function of 500 ms on the while loop to check that the registers responsible and clear. I'm glad that it worked very well!
I'm in LabVIEW FPGA 8.6 with NOR-RIO 3.0.1 (to 8.6). When I compile a simple program, I get the notorious:
«Error starting compile step: make sure that a compatible version of Xilinx tools is installed in the location specified in the setup of LabVIEW FPGA.»
I checked the FPGA compile server and I ran the utility fixTlink.VI with no improvement. This produces two identical PC, neither one having a FPGA installed card.
After further analysis, the problem was to be in our facility in LabVIEW FPGA 8.6. Using the correct Installer of NEITHER solved the problem.
This thread is now resolved.
I did a first compilation for the SMU with the Xilinx Vivado 2014.4 tool 7820 (64-bit). Compilation report said.
Compilation successfully completed.

This means no timetable? The embedded clock's 40 MHz. It runs with this clock? Beacause 7833 compilations for the pci or pcie 7842 report displays the maximum clock time.
"none" means simply from what I can understand, that there is no violation of timing. The source of synchronization that will be used is (as you have already suspected it) on-board 40 MHz clock.
As to why you don't get a mention of the MiteClk and the ReliableClk in summary, I think that it is due the 7833 and the 7842 relying on FPGA Virtex-II and Virtex-5, while the 7820 uses the Kintex-7 family. Depending on what type FPGA using different estimates regarding the use of the device and synchronization are not always available.
As I said, as long as you don't get not an error of timing and your compilation is completed successfully, you should be fine.
I get the error next (in a pop-up window) in the phase of sompilation for the FPGA target with a vhdl IP. This error continues to occur even after restart LabVIEW and the PC. Someone at - it solved is this kind of problem before without having to re - install the software?
Here is the error information:
Error-61499 occurred at niFpgaXml_GetValue_String.vi<><><><>
LabVIEW FPGA: An internal software error in the LabVIEW FPGA Module has occurred. Please contact National Instruments technical support on ni.com/support.
Additional information: lack the tag required XML (/ CompileServerList)
As a first step, I can compile the vhdl IP node successfully. However, once when I'm running a VI with the FPGA, the bureau stop working. After that I restarted by force, it cannot perform the build of a vhdl IP node. Even without connecing to the jury of LabView, he pointed out errors before the end of the sompilation.
Interestingly, the screw which also includes nodes IP vhdl that I properly compiled before, I can still run the VI to the Commission and it works correctly.
Looks like your ActiveJobsList somehow has been corrupted. I saw occur when computers are hard stop or blue screen during compilation. I don't have that LabVIEW 2014 installed on my machine, so your path will be a little different, and the file extension will be a .txt or .xml instead of .json, but try this:
Move the file "C:\Program Files (x 86) \National Instruments\LabVIEW 2014\vi.lib\rvi\CDR\niFpgaActiveJobList.json" (or your equivalent) out of the above directory (back it upward and delete essentially) and restart LabVIEW. Must regenerate the file and resolve the problem.
I'm new to LabView FPGA and am currently trying to compile my VI on the target FPGA (an NI PXI-7842R).
The initial phase (what seems like Labview generating the VHDL code) appears to run successfully.
The next step (which seems to be the actual compilation on the FPGA) runs for a short time, and then reports an error at the end of the phase of PlanAhead.
The error message says:
LabVIEW FPGA: An internal software error in the worker of compilation occurred.
Error-61330 occurred at niFpgaCompileWorker_ProcessStatusPipe.vi:640001<><>

I use 2013 LabView, the module 2013 FPGA and Xilinx tools 14.4 on Windows XP SP3.
I need to pass an index memory RAM of LabVIEW FPGA block to a CLIP node to the node CLIP to have access to the data in the BRAM. The node of the ELEMENT contains an IP address that we developed and the IP address is the use of Xilinx BRAM driver to access data. I guess that we need to move the physical address of the BRAM to the ELEMENT node.
Is this possible? If so, how? If this is not the case, what would be an alternative?
If I understand you correctly, Yes, you should be able to use the memory block of the Xilinx pallet Builder in LabVIEW FPGA and in the loop of the single Cycle, connect the ports of this block signals CLIP exposed by the IP of your colleague. You may need to tweak/adapt some of the signals slightly to the LabVIEW data flow.
Please help me for this problem "error starting compile step: make sure that a compatible version of Xilinx tools is installed in the location specified in the setup of LabVIEW FPGA.»
Look for the error on the Web site of or or on the forums. Take a look at the following links:
I've recently switched to LabVIEW 2015 and I'm working on OR myRIO. So also installed myRIO 2015 bundled software. The problem I have is that the compilation of fpga fails within 10 seconds.
and the target Xilinx journal report is empty
The first time when I tried to compile on 2015 version, it failed and the message box that failed came alongwith the avast antivirus warning for malicious activity. I reported it as wrong and now I tried several times with avast shield disabled control, but the results are the same. While the version of labVIEW 2014 works very well.
Now, I'm sure that there is something wrong with the installation of Vivado because this dll is part of it. The dll must be default in the2014_4\lib\win32.o directory C:\NIFPGA\programs\Vivado if you are using an operating system for 32-bit AND also in C:\NIFPGA\programs\Vivado2014_4\lib\win64.o If you use a 64-bit operating system. If the dll is not here, it is probably that the anti virus (I've never seen what happens to Xilinx but I have for other stuff).
I'm emphasizing the 2014_4 because LabVIEW 2015 uses Vivado 2014_4 while 2014 LabVIEW uses Vivado 2013_4. Since you have also installed LabVIEW 2014, you must have 2013_4 as well and if it works, you will find the dll I just wanted you make sure you check the correct directory for the Vivado 2014_4.
Download and install (reinstall or repair if already installed) 2015 LabVIEW FPGA Module Xilinx tools Vivado 2014.4. You can also use the DVD Setup if you have. It would be a good idea to do the installation with the disabled and even anti-virus try the first compilation the same. Try and let me know if the problem persists.
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:
ERRORortability:3 - Xilinx this application runs out of memory or met a memory conflict. Use of current memory is 4167696 KB. You can try to increase physical or virtual memory of your system. If you are using a Win32 system, you can increase your application from 2 GB to 3 GB memory using the 3 G switch in your boot.ini file. For more information, please visit Xilinx answer Record #14932. For technical support on this issue, you can open a WebCase with this project attached to http://www.xilinx.com/support.
"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.
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.
Current versions of software:

I'm having a huge problem in trying to compile my LabVIEW FPGA code.
Some recall of the code:
It's all in a SCTL.
I am streaming in a FIFO DMA and comparing it with the values previously stored in the shift registers (which are initialized to 0 at the start of the loop) in the SCTL.
The results of the comparison are then piled into a U16 and loaded into a lookup table (I use the LUT - 1 d), and I'm so help this LUT to decide what value will be charged to travel to record for the next iteration of the loop, which, in any case, would be either the current values of the flow, or the post previous registry value.
(It's a triage loop)
I am able to run very well in simulation mode code, but when I try to compile, I get this error:
"The selected object has a built-in shift register that makes the output on a particular loop iteration correspond to the entries in the previous iteration."
Connect the outputs of the object directly to a minimum number of nodes of Feedback or uninitialized shift registers. You cannot connect the outputs to another object.
See using LabVIEW for more information on the objects with registers embedded offset. »
Someone at - it ideas why this happens, and what might be the possible solutions?
I'm tempted to break it down into separate loops, but I prefer not to because it is now a loop (and working in my simulation).
I found my problem.
Any time that a LUT is in a chain shift register, it cannot:
1. be part of a string of shift register that has a variable initialized
2. follow-up to no decisive structure, like a box structure.
I just moved the position of LUT and it works.
I am having trouble with the integration of LabVIEW FPGA IP option and was hoping someone could shed some light here.
I use a simple VHDL code for a bit, 2: 1 MUX in order to familiarize themselves with the integration of IP for the LabVIEW FPGA.
In the IP properties of the context node, the syntax checking integration says:
ERROR: HDLParsers:813 - "C:/NIFPGA/iptemp/ipin482231194540D2B0CC68A8AF0F43AAED/TwoToOneOneBitMux.vhd", line 15. Enumerated value U is absent from the selection.
but I'm still able to compile. Once the node is made and connected, I get the arrow to run the VI but when I do, I get a build errors in Code Pop up that says:
The selected object is only supported inside the single-cycle Timed loop.
Place a single cycle timed loop around the object.
The selected object in question is my IP integration node.
I add a loop timed to the node, but even if I am able to run the VI, it nothing happens. the output does not illuminate regardless of the configuration.
I would say that I tried everything, but I can't imagine would be the problem might be at this point given that everything compiles and the code is so simple.
I have attached the VI both VHDL code. Please let me know if any problems occur following different boards of the FPGA.
Would be really grateful for the help,
Looks that you enter in the loop timed Cycle and never, leave while the indicator of Output never actually is updated. Try a real constant of wiring to the break of the SCTL condition. Otherwise, you could spend all controls/indicators inside the SCTL and get rid of the outside while loop. You can race in the calendar of meeting bad in larger designs without pipeling or by optimizing the code if you take this approach, however.
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.
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!
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).
