Welcome to the IP Integration Node

vwan,

Thank you for the response.  I am currently going through my code and commenting out different sections in order to find the problem.  I wanted to bring up that I have already checked my syntax in ISE and I don't have any compilation errors in ModelSIM.  Do you know which type of expressions or lack of expressions would cause this error?

Thanks,

Travis

vwan,

My problem is occuring because of the DSP48E instantiations that I am using.   Please note that I am using the UNISIM library along with these instantiations:

Library UNISIM;
use UNISIM.vcomponents.all;

I'll keep you updated.  Thanks for your help.

It will be interesting to know what you find out. I know others have been successful simulating the DSP48 block. FYI: we are using features of ISIM to provide the simulation: http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/plugin_ism.pdf. You might be able to use ISIM outside of LV to help narrow down the problem faster...

I've recently obtained a new laptop, and in my efforts to use the IP Integration node I'm seeing the same problem numerous times.  When I open a file that contains the IP integration node, the error says that "The procedure entry point (entry point name) ccould not be located in the dynamic link library libPortability.dll."

I've attached a screenshot of my error.

Additionally, once I have the VI open.  I can double click on the IP integration node and open the configuration window, but the window is blank. 

Any ideas?

It seemed like some errors occurred when loading DLLs. Maybe you can check the environment variables to see if the following environment variables were set correctly:

XILINX = <NIFPGA Folder>\Xilinx\ISE, for example: XILINX = D:\NIFPGA2009\Xilinx\ISE

Path = %XILINX%\lib\nt; %XILINX%\bin\nt; <original Path value>

We'll resolve the environment variable issues during productizing this feature.

Everything seems to be fine with the environment variables.  I checked them against the environment variables in the lab and they are identical.  Any more suggestions?

[thill]

Problem fixed!  All I did was uninstall the ISE design suite, uninstall the IP Integration node, and re-install the IP Integration node.  Based on my experience, the order of installation is what fixed this issue.  On previous installations, I always had LabVIEW installed before I had Xilinx installed.   This time I had Xilinx installed first and it caused the IP integration node failure.

hi,

is there any way to implement DWT/STFT in labview fpga. is any IP available?

thnks

Hi sed_y,

We don't have DWT and STFT in LabVIEW FPGA now. It is possible that some 3rd party companies have such IPs. If you buy their IPs, you can integrate it to LabVIEW FPGA with IP Integration Node.

We now have the FFT and Window node in LabVIEW FPGA, is it possible for you to build the DWT and STFT by yourself?

P.S. Would you let us know your use case? We have been collecting use cases to see whether we should develop the wavelet and time-frequency related nodes.

I've tried installing the IP Integration Node but no matter where I look for it I can't find it in my palettes or the program files directory. Has this happened to anyone before and if so is there a fix?
