I am trying to perform a post-synthesis simulation using Xcelium and have SimVision display the waveforms. Xrun seems to run just fine by itself, but if I tell it to use the GUI to show the waveforms, the whole thing comes to a screeching halt (10+ minutes to do anything). I also get this behavior if I try to open SimVision by itself with no simulation. I don't have this issue with other GUI tools like Virtuoso or MATLAB. The server this simulation is running on is CentOS 7 machine which I access using x2go or VNC. I am using Xcelium 19.03. I was wondering if anyone has experienced a similar issue with SimVision performing so slowly compared to other graphical tools and if there is a fix.
