HLS fox simulation

[sarpadi]

Hi guys,

I am trying to bring up the HLS edge detection design using Vitis HLS 2022.2 on ubuntu 22.04.02. I saw that there are some issues regarding the newer versions of HLS.

So far I believe I managed to synthesize the edge_detect core. I believe the vision library was added correctly with CFLAG (although I haven't tested it on an FPGA) but I keep having trouble with the simulation part. I tried using opencv 4.4.0 and 3.4.16 an I keep getting the same errors

Has anybody seen these error before? Did anyone manage to run the simulation on the core? Any help would be useful at this point.

thanks,

Hi @sarpadi,
Double check your environment to see if OpenCV is referenced correctly inside Vitis HLS.
This Answer Record goes into detail on how to reference OpenCV after installing it:
https://support.xilinx.com/s/article/75727?language=en_US

From my experience, setting this up is way easier using a tcl script.
I have attached an example for setting up a Vitis HLS 2020 project (should be the same for 2022). Note that I set this up using windows, so double check the library includes.

Hi @Niță Eduard,

Thank you for your help

In the end the problem was in the way we were running the Xilinx instructions on how to build Opencv. The tools changed a lot since vitis came along and it seems I underestimated the impact.
