Hi,

The demo is really useful. I am using your socket libraries to run with simulation using Questa MTI (latest version - 2023).
I noticed that when there is no traffic from the Host/QEMU to simulation, the simulator blocks (hangs) at socket functions such as read/write/select, and it can not advance to the next simulation time slot and it stucks forever.
I have tried blocking and non-blocking socket, but I got the same issue.
I don't see this issue happens in VCS simulator.

Has anyone seen the same issue for Questa sim?
