QuestaSim is a proprietary tool. Even if you make the files portable, you still require a valid license file ( .dat ) or license server connection.

If your goal is simply to simulate Verilog/VHDL on any Linux machine (without the QuestaSim brand), here are options you can download and run from USB today.

Even if the technical hurdles of dependencies are overcome, the most significant barrier is the FlexNet (FLEXlm) licensing system. QuestaSim requires a valid license file to operate. Commercial licenses are typically tied to a specific Ethernet MAC address (HostID) or a dedicated license server.

If using a node-locked license, the "portability" is limited to the specific hardware (MAC address) the license is tied to. Best Practices for Portable EDA download questasim for linux portable

Ensure that you decline any prompt asking to create global desktop shortcuts, register system service daemons, or modify system-wide initialization scripts. Step 3: Resolve Linux Dependency Conflicts Locally

How to Get QuestaSim for Linux: A Guide to Portable Environments QuestaSim is a proprietary tool

If you are a student, researcher, or hobbyist, the easiest legal way is to use the . Intel distributes a free (but limited) version of QuestaSim bundled with Quartus Prime Lite. You can download the Linux version of the "Questa*-Intel® FPGA Starter Edition" directly from the Intel Download Center. For example, the license edition for version 23.1.1 is known to work well on modern Ubuntu distributions. This version is limited to a moderate device size but is perfect for learning and small projects.
