I’m using Vivado 2024.1 with my AU.
The WebPack Edition does not exist anymore and the Standard Edition is now free.
In the installer, after logging in to your account.
Pick the “Vivado” entry and click Next
Pick “Vivado ML Standard” and click Next
Untick Vitis Model Composer (you probably won’t need unless you are a professional)
If you plan to use soft-processor (MicroBlaze), you need to tick “Vitis Embedded Development”
In the “Devices” section, you can untick everything but Artix-7 (in the “7 Series”).
Then you should be ready to go
EDIT: Sorry I missread that you already have Vivado installed.
There is no additionnal setup steps unless you want your AU to be detected within Vivado (can be very usefull since it allows to use the ILA IP, and allows to program the FPGA without leaving Vivado, but you still need the Alchitry Loader to program the embedded flash).
