I very rarely see any Debian based Linux in use in ASIC companies, virtually everyone uses RedHat, and there's a cost to supporting different platforms (compute infrastructure to test each release, engineering effort to handle inconsistencies between platforms etc). Cadence does watch the market and does add or remove platforms based on market trends. For example we recently added support for Arm v8 on Red Hat, based on customer demand. Anyway, to your specific question, you might need to install a few extra system libraries; I've noticed that Ubuntu seems to only install the 64-bit libraries by default, and Xcelium tries to run 32-bit by default (for best performance). Here's what I had to install to get a basic sanity test to build and run on Ubuntu desktop 19.04 LTS: Ensure the required shell interpreters are available: sudo apt install tcsh sudo apt install ksh cd /bin sudo rm sh sudo ln -s bash sh Because no 32-bit support on the default OS install! export PATH=/xcelium/19.03.003/tools/bin/64bit:$PATH Fix "invalid" paths in /usr/include (Ubuntu adds an extra hierarchy level c.f. RHEL): cd /usr/include/ sudo ln -s x86_64-linux-gnu/sys sys sudo ln -s x86_64-linux-gnu/bits bits sudo ln -s x86_64-linux-gnu/asm asm sudo ln -s x86_64-linux-gnu/gnu gnu If you find you need to make further tweaks, please do share the knowledge back here, to help anyone else who wants to use Ubuntu.
