: Prevents the export_ip command from failing with "Invalid Argument" or "Revision Number Overflow" errors.
If you are a digital designer using Xilinx (now part of AMD) Vivado or Vitis HLS tools, you may have encountered a sudden failure to generate or export IP cores around 2022. This is likely due to the "Y2K22 bug," a date-related issue in the software's internal timestamp handling. This comprehensive guide provides a detailed, step-by-step walkthrough to identify, download, and install the necessary y2k22_patch on both Windows and Linux systems.
Execute the script using your system or Xilinx-bundled Python: python3 patch.py Use code with caution. Method 2: Manual Installation
Are you currently seeing a like [Vivado 12-8300] while trying to generate your IP? Y2k22 patch does not seem to work - Adaptive Support If you are a digital designer using Xilinx
You must identify the absolute path to your AMD Xilinx installation's root directory. This is the directory that contains sub-folders like Vivado , Vitis_HLS , DocNav , etc.
Attempt to clear and regenerate the output products for that IP.
The Y2K22 issue is a problem that arises from the way some systems store and process years. Similar to the Y2K problem (which was a widespread concern at the turn of the millennium), the Y2K22 issue could cause problems when systems use only two digits to represent the year. When the year 2022 arrives, systems not designed to handle four-digit years properly might behave unexpectedly.

A: Yes, the patch is designed to work with versions from 2014 up to 2021.x. However, for very old versions like 2017.2, you might need to use the manual workaround mentioned earlier.

In January 2022, FPGA engineers worldwide were hit by the "Y2K22" bug, which caused Vivado and Vitis HLS (High-Level Synthesis) to fail during IP export. The issue stemmed from a date-based versioning system (
. Without this patch, High-Level Synthesis (HLS) tools fail to export IP because the date-based version number (YYMMDDHHMM) exceeds the limit of a 32-bit signed integer, causing an overflow error. Quick Installation Guide
