[HLS fox simulation]

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.

[HLS fox simulation]

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,
