Vivado Y2k22 Patch Install

The Vivado Y2K22 patch (specifically patch version 1.2) is a critical update released by AMD-Xilinx to address a major overflow bug in High-Level Synthesis (HLS) and IP export tools. Without this patch, Vivado and Vitis versions from 2014.x through 2021.2 are unable to export IP because the revision number, which includes a date-based timestamp, exceeds the limits of a 32-bit signed integer. Prerequisites for Installation

Before beginning, ensure your environment meets these requirements:

Python Requirement: You must have Python 2.7.5 or later installed.

For Vivado 2019.x and newer, you can use the Python version bundled with the Xilinx installation.

For 2018.3 and earlier, a standalone Python 2.7 installation is required.

Version Compatibility: This patch applies to Vivado and Vitis versions 2014.x through 2021.2. vivado y2k22 patch install

Permissions: You will likely need administrative (Windows) or root (sudo) privileges on Linux. Step-by-Step Installation Guide 1. Download the Patch

Navigate to the AMD Support Solution (AR 76960) and download the y2k22_patch-1.2.zip file. 2. Extract the Files

Extract the contents of the ZIP file directly into your base Xilinx installation directory. Windows: Typically C:\Xilinx. Linux: Typically /tools/Xilinx or /opt/Xilinx.

Important Note: Ensure the extraction does not create a subfolder named after the ZIP file. The final path should look like C:\Xilinx\y2k22_patch. 3. Execute the Patch Script

Open a terminal or command prompt and navigate to the base installation directory where you extracted the patch. The Vivado Y2K22 patch (specifically patch version 1

On Windows:Run the following command using the bundled Python or your system's Python 2.7: python y2k22_patch\patch.py Use code with caution.

On Linux:To avoid dependency issues, it is recommended to set the LD_LIBRARY_PATH to the Python library folder within your specific Vivado version before running the script. For example:

export LD_LIBRARY_PATH=$PWD/Vivado/2021.2/tps/lnx64/python-3.8.3/lib/ python y2k22_patch/patch.py Use code with caution.

Alternatively, you can call the bundled Python directly: /tools/Xilinx/Vivado/2021.2/tps/lnx64/python-3.8.3/bin/python y2k22_patch/patch.py. Verification and Troubleshooting

Success Confirmation: After running the script, the tool will report that it has added custom Tcl files to the installation locations to prevent the overflow. For Vivado 2019

Validation: Test the installation by attempting an export_design command in Vitis HLS or exporting an IP in Vivado. It should no longer throw the "invalid argument" or "revision number overflow" error.

Persistent Errors: If you still see the error 2201220914 is an invalid argument, ensure the script was run from the base directory and not from within the patch folder itself.

Updates: If you apply the patch to a base version (e.g., 2021.1) and later install a minor update (e.g., 2021.1.1), you do not need to re-apply the patch.

Identifying the Correct Patch

Before proceeding with the installation, it's crucial to identify the correct Vivado Y2K22 patch for your version of Vivado. Xilinx typically provides patches through its official support website, where users can find and download patches specific to their Vivado version. Ensure that you select the patch that corresponds to your software version to avoid compatibility issues.

3. Close All Xilinx Tools

Ensure Vivado, Vitis, SDK, Hardware Server, and any Xilinx license managers are fully closed. On Windows, check Task Manager for processes like vivado.exe, xsct.exe, xilinx-d.exe.

1. Identify Your Exact Vivado Version

Open Vivado, go to Help > About Vivado. Note the major, minor, and patch version (e.g., 2021.2.0 build 1234567). The patch is version-specific.
