After 8 months of production use across multiple designs, the engineering consensus is clear:
Vivado 2020.2 (e.g., for fixed-point neural network acceleration), search libraries like IEEE Xplore ResearchGate "FPGA acceleration fixed-point Vivado 2020.2"
Vivado consumes 32GB+ RAM and crashes after 4 hours of interactive Tcl scripting. Fix: Use batch mode for large Tcl scripts:

The MIPI CSI-2 RX Subsystem v5.1 had a known issue in the 2020.2 release, particularly affecting early silicon (ES1) versions of the VCK190 board. This problem was fixed in the 2021.1 version of the tools, but a patch was made available for users who needed to stay on 2020.2. If you're using the production version of the VCK190 board, upgrading to 2021.1 is recommended, but a patch exists for those locked to 2020.2.

AMD limits active technical web installer hosting authentication to a rolling . Because Vivado 2020.2 is past this lifecycle window, the lightweight web installer executable can no longer successfully handshake with the download servers.
