A: No. The patch modifies the tool binaries and license daemon only. Your project files, constraints, and source RTL remain untouched. However, you should re-generate all IP cores after patching to clear any date-stamped cache.
This guide will walk you through the installation process for both Windows and Linux environments. The steps are largely similar, with differences primarily in the directory paths and Python executable names.

This issue is rooted in a date overflow problem within the software. Around the start of 2022, AMD/Xilinx identified that the High-Level Synthesis (HLS) tools in Vivado and Vitis were experiencing a significant bug, quickly named the "Y2K22" issue. The software uses a date code to manage IP versioning, and starting in January 2022, this value overflowed, preventing the correct generation of IP cores. vivado y2k22 patch install
The Y2K22 bug, while disruptive, has a straightforward fix through the official AMD Xilinx patch. By carefully following the steps outlined in this guide—downloading the patch from the official source, extracting it correctly, and running the included script with the correct Python interpreter—you can quickly restore full functionality to your HLS design flow.
You can find the official patch and detailed steps on the AMD Adaptive Support site .
