QuestaSim Starter Version 202x.x ... To compile and simulate a tiny design: download questasim for linux

If you’re working with SystemVerilog, UVM, or complex FPGA designs on a Linux workstation, Siemens QuestaSim is one of the most powerful simulators you can use. But getting the software legally and installing it on Linux can be confusing. sudo apt update sudo apt install -y libxft2

sudo yum install -y libXft libXmu libXext libX11 libXrender freetype fontconfig libXScrnSaver libXtst libXi libSM libICE Also ensure gcc , g++ , and make are installed – QuestaSim uses them for compiled libraries. Create an install directory (avoid system-owned folders like /usr/local to prevent permission issues): sudo yum install -y libXft libXmu libXext libX11

mkdir -p ~/intelFPGA/questa_sim chmod +x questasim-linux_x86_64-202x.x.run ./questasim-linux_x86_64-202x.x.run --mode text --prefix ~/intelFPGA/questa_sim For GUI installer (if you have X11 forwarding):
