Instead of installing it to /opt/questa , you will install it to a portable directory, such as a USB drive or a dedicated folder in your home directory.
Create a short text file named run_questa.sh inside your folder. Add the environment variables to this script. This tells the software where to find its own files and license. download questasim for linux portable
QuestaSim, developed by Siemens EDA (formerly Mentor Graphics), is one of the most powerful and widely used simulation tools for RTL verification in the semiconductor industry. Supporting advanced standards like SystemVerilog and VHDL, it is a staple for FPGA and ASIC engineers.
Setting up the environment is the final step in the portability workflow. Since a portable version does not integrate with the system path, a "sourcable" shell script is essential. This script should define the QUESTASIM_HOME , update the PATH to include the compiler and simulator executables (vlog, vcom, vsim), and set the necessary locale variables to prevent font or display errors in the graphical user interface. By encapsulating these settings in a single script, the user can initialize the entire toolchain in seconds on any compatible Linux distribution. : Instead of a traditional install, it leverages
A wrapper script to set up environment variables automatically.
