System generator black box sim bug, has hardcoded path!

Hello,

 

I've got a Vivado 2016.4 block diagram containing custom logic as well as a FIR Compiler 7.2 block. I generated output products for it and wanted to simulate it as a black box in System Generator. It failed, and the elaboration log spat out a Xilinx hardocded path that screwed everything up. Here is the contents of elaborate.log:

Please fix.

Hi @dima2882 ,

 

Can you share your project?

 

Thanks,

Re: System generator black box sim bug, has hardcoded path!

Hi @srimaye,

 

Absolutely can share the project, I just sent you a PM. Let me know if you want it another way.

 

I made sure all of the paths work and saved everything to a tarball. It's not very big - in testing I cut out everything unrelated to the error, so the Vivado block basically contains the FIR compiler and a wrapper, nothing else.

@jamey.hicks:

 

Did you run into this in Vivado 2016.4 or 2017.1? The latter was not yet out when I hit this bug...

Re: System generator black box sim bug, has hardcoded path!

I only tested it in 2016.4. If I have time, I'll try it with 2017.1 today.

Same behavior with 2017.1.

Re: System generator black box sim bug, has hardcoded path!

Has this issue been resolved?

 

I'm having a similar problem in Vivado 2017.2 using the sysgen black box with a CFR module.

 

Thanks

Mark

Re: System generator black box sim bug, has hardcoded path!

Doesn't look like this has been solved, still have the same problem on 2017.2. Zero response from Xilinx on this.

I've got the same problem here with Vivado 2017.4. Still no response from Xilinx?

Is it possible to share the project files?

Re: System generator black box sim bug, has hardcoded path!

zip file attached. Go to 'simulationRun' folder and run ..\xe.bat. That produces the following error:

 

ERROR: [VRFC 10-2553] file 'filepointer' is not open [/wrk/2017.4/nightly/2017_12_15_2086221/packages/customer/vivado/data/ip/xilinx/fir_compiler_v7_2/hdl/fir_compiler_v7_2_vh_rfs.vhd:4369]

@dfs342602707

Do you have .slx for the design. I am getting different set of errors for the code in the zip file.

Re: System generator black box sim bug, has hardcoded path!

hi,

 

I do not have an .slx file. I have not used Matlab or Simulink for this. Attached is a project that was used to create the filter.

I seem to be very much alone when using the Xilinx Forums :(

Re: System generator black box sim bug, has hardcoded path!

Yea, we all feel that way... Getting Xilinx to fix something when the forum is the only link to them just doesn't work.

Gotta be the kind of large customer they listen to :)

Re: System generator black box sim bug, has hardcoded path!

Hi,

I got this example working by copying fir_compiler_1.mif file to simulationRun folder, the elaboration just did not find the coefficient file.
