Vivado HLS not found and PYNQ-ZU for ver. 1.0.0.0

[Viggo-Avila]

I'm doing part 7a of the tutorials and I'm having trouble at the making of the bitfile. My issue is that when I run it I get an error saying the Vivado HLS is not found or I have to make sure that vivado_hls is on my path. I'm not sure how to do it, my source is pointed towards vitis_hls settings64.sh file and i've been doing the tutorial with that as the source. As far as I know I didn't miss any Vivado HLS during the installation of the unfiied installer and from what I've read (I don't know where I kind of forgot) that Vivado HLS is already included with the installation of Vivado. I've been trying to find ways on how to install Vivado HLS but no answers come up, even on the Add devices option in the vivado ide. So, my question is do I keep on finding ways to download Vivado HLS? or should I just change the backend and stuff into Vitis HLS? if im going to change to Vitis, how do I do it because I've tried to change some stuff like changing VivadoAccelerator to VitisAccelerator and it doesn't seem to be working.

also, some bonus info: the FPGA i'm using is the pynq-zu and so since the tutorial uses the PYNQ-Z2 i tried to change it from there. I found this solution https://github.com/fastmachinelearning/hls4ml/issues/623#issuecomment-1199507304 and when I installed it the hls4ml version changed from 1.0.0.0 to some 0.6.0.dev172+ge64619d3 is there already support for the PYNQ-Zu in version 1.0.0.0 that I might've missed?

Hi!

The issue is that we do not have an Accelerator backend for Vitis HLS yet. There are open PRs for this (#991 and #1134), but it's still work in progress.

So for this part of the tutorial, Vivado HLS needs to be used, together with the VivadoAccelator backend. You will need to install Vivado 2019.2 or 2020.1 for this, see https://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/vivado-design-tools/archive.html.

+1. I also would like some pointers for converting the generated Vitis project to bitstream, which have been automated in VivadoAccelerator I believe.

I also curious that if I can do it on vivado 2024 , did @Viggo-Avila @DivineMK you guys figure it out?
i'm failing at part7

Unfortunately no, I had to install another version of Vivado (Vivado 2020.1) so that I can do part 7. So if I were to do Parts 1 to 6 I would have to set my source to Vivado 2024.1 settings64.sh, and if I were to do Part 7 I would change my source to Vivado 2020.1 settings64.sh

May I ask which OS did you use? It seems that Vivado 2020.1 only support to ubuntu18.04, but I'm on Ubuntu 24.04, I'm wondering if I can still use it or I need to install a new ubuntu18.04

Ah I forgot, which one I had I'm no longer have access to the computer but I think you do have to change it yeah. If i remember the quartus version is 2020 something?
