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 (
The bug affected projects relying on absolute timestamps, specifically those crossing the 2022 boundary. Attempting to build a project after Jan 1, 2022, without the patch would result in catastrophic failure. vivado y2k22 patch install

In January 2022, users worldwide discovered that Vivado would crash or throw license checkout errors when the system date rolled past January 1, 2022. The root cause was a classic "Y2K-like" integer overflow or string parsing error in the vendor daemon (xilinxd) and certain build scripts. In January 2022, FPGA engineers worldwide were hit
