| Problem | Solution | |--------|----------| | | Set XILINXD_LICENSE_FILE to 2100@license_server or local .lic file. Use lmutil to verify. | | Vivado crashes on launch (Java error) | Delete C:\Users\<user>\.Xilinx\ Vivado\2020.2\logs and vivado.jou . Or run vivado -clean . | | Simulation fails: "Failed to compile c model" | Install 64-bit GCC. On Linux: sudo apt install gcc-multilib . | | HLS IP generation error: "Unknown OS" | Set TCL_LIBRARY and TCLLIBPATH correctly. Use export LC_ALL=C before launch. | | Vivado hangs at "Starting local server" | Disable IPv6: add -noipt to vivado.bat or run vivado -noipt . | | Memory errors during implementation | Increase swap space: Linux fallocate -l 16G /swapfile . Windows increase virtual memory. | | Ubuntu 22.04 – libtinfo.so.5 missing | sudo apt install libtinfo5 (or symlink libtinfo.so.6 to .5) | | Partial reconfiguration not working | Install 2020.2.2 update – contains critical PR fixes. |
