Can I use Vivado 24

[DrBwts]

I see the recommendations are Vivado HLS versions between 2018.2 and 2020.1 but will HLS4ML still work with Vivado 2024.1?

[JanFSchulte]

What was used to be called Vivado HLS is now Vitis HLS, so for newer versions of the Xilinx tools, you can use the Vitis backend in hls4ml. If I understand the current product naming correctly, Vivado 2024.1 does not support HLS but is rather meant for HDL design. So Vitis HLS is the tool to use for work with hsl4ml.

And just to be clear, you can use the IP produced with Vitis HLS in Vivado. It's just that Vivado HLS no longer exists.

So I'll be OK using the latest integrated Vivado/Vitis 2024 install?

[JanFSchulte]

Yes, if you use the Vitis backend in hls4ml, that should work. I'm not 100% sure how much we have tested the latest Vitis version, though, maybe @jmitrevs and @vloncar can comment on that.

I personally haven't used 2024.x much, but I would expect it to work. You should use the main branch of hls4ml, though, not the tagged release. Vitis HLS 2022.2 and later should be supported.
