Q: Do I need the Y2K22 patch if I always keep my system date correct?

Q: Can I just upgrade to Vivado 2023.1 instead of patching?
A: Upgrading is the best long-term solution. However, if you must maintain source compatibility with a team using 2021.2 or support a legacy board/vendor IP, the patch is mandatory.
Q: Will the patch affect my existing projects?
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.
Q: Does the patch work for Vitis HLS or Petalinux?
A: Partially. The Y2K22 patch specifically targets Vivado and the common license manager. Vitis HLS 2021.x requires a separate hotfix. Refer to AR# 77351 for Vitis.
