If you want to run QuestaSim on a modern distro (like Ubuntu 24.04) without worrying about old library dependencies, use Docker.
The primary obstacle to a portable QuestaSim on Linux is binary architecture. Historically, QuestaSim relied heavily on 32-bit libraries (i386). While newer versions (Questa 2020+) have transitioned to 64-bit, many legacy flows and mixed-language simulations still call upon 32-bit dependencies. download questasim for linux portable
Create a startup script setup_questa.sh in the portable folder: If you want to run QuestaSim on a
QuestaSim is commercial, license-managed, and installed via standard EDA installers. “Portable” versions you find on torrents, GitHub, or forums are cracked, outdated (e.g., 2020.1–2021.3), and risky. They can work in a limited sense but are not recommended for serious work. While newer versions (Questa 2020+) have transitioned to
Installing 32-bit compatibility libraries (often required even on 64-bit systems) and ensuring the shell (typically ) is correctly configured. The Environment: Defining the directory and setting the LM_LICENSE_FILE
