QuestaSim is Mentor Graphics’ (now Siemens EDA) high-performance simulator for FPGA and ASIC verification, supporting SystemVerilog, VHDL, and mixed-language designs. While the standard installation requires a license server and system-wide configuration, many engineers need a – one that can be moved between machines or run from a USB drive without root access. : Intel provides a "Lite" or "Starter" edition
The primary challenge in creating or obtaining a portable version of QuestaSim for Linux lies in its reliance on shared system libraries. Like most EDA tools, QuestaSim is compiled against specific versions of libraries such as glibc, libX11, and various motif packages. On a standard installation, these are managed by the OS package manager. To make the software portable, one must use a "bundled" approach, where all necessary .so files are contained within the application folder. Tools like AppImage or simple wrapper scripts that modify the LD_LIBRARY_PATH are commonly employed to ensure the binaries look within their own directory for dependencies rather than the host system's /usr/lib folders. The primary challenge in creating or obtaining a
