generating matrix multiplication IP core

[Altera_Forum]

Hi,  

when I generated the matrix multiplication IP core in Quartus 16.1, the system showed error information as follows.   Info: Starting: Create HDL design files for synthesis Info: qsys-generate C:\intelFPGA\16.1\temp\multi.qsys --synthesis=VHDL --greybox --output-directory=C:\intelFPGA\16.1\temp\multi --family="Arria 10" --part=10AX115R3F40I2SGE2 Progress: Loading temp/multi.qsys Progress: Reading input file Progress: Adding fp_matrix_mult_ii_0 [altera_fp_matrix_mult_ii 16.1] Progress: Parameterizing module fp_matrix_mult_ii_0 Progress: Building connections Progress: Parameterizing connections Progress: Validating Progress: Done reading input file Info: multi: "Transforming system: multi" Info: multi: Running transform generation_view_transform Info: multi: Running transform generation_view_transform took 0.000s Info: fp_matrix_mult_ii_0: Running transform generation_view_transform Info: fp_matrix_mult_ii_0: Running transform generation_view_transform took 0.000s Info: multi: Running transform merlin_avalon_transform Info: multi: Running transform merlin_avalon_transform took 0.067s Info: multi: "Naming system components in system: multi" Info: multi: "Processing generation queue" Info: multi: "Generating: multi" Info: multi: "Generating: multi_altera_fp_matrix_mult_ii_161_k7waf2q" Info: fp_matrix_mult_ii_0: C:/intelfpga/16.1/quartus/../hls/bin/internal_matrixmult_helper --fp-relaxed -march=altera --RTL-only -o matrix_mult --device {Arria 10} --clang-arg -generate-altera-ip -I.

The errors were same. Could you give me some comments to solve this problem.  Thanks a lot  Tan

I would try with a project directory in user space. Windows might have remapped files because the Quartus directory has restricted access.

Hi, FvM, 

 Thanks for your reply. I also generated the IP in the Linux environment. The errors are same.

Windows might have remapped files because the Quartus directory has restricted access.

I am also having this problem, but on the Cyclone V and with the Random Number Generator IP Core on 18.0 and 18.1. Still a problem even when the directory is in the user space... Intel needs to fix these issues!

In case anyone else has a similar problem, I fixed my issue by realizing that it was an issue with the libraries in the HLS compiler not being recognized. So I looked up the documents and realized that I did not have the correct version of Visual Studio downloaded (if using Windows) to support the quartus version I was running. Quartus only supports older versions of Visual Studio and their libraries. This might not fix the specific issue above, but with the issue I had, I simply had to download the correct version of VS (2010 for Quartus/HLS 18.0). Then Quartus was able to find and use the correct libraries it needed to generate the IP Cores. This information came from the Intel HLS compiler release notes, version 18.0 linked here: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/rn/archives/rn-hls-18-0.pdf

Hope this helps some others!
