I'm trying to configure the tools in my personal machine. When I try to simulate from xschem after making the netlist ngspice doesn't start up. Instead, it shows

Simulation Started

in the console, which never ends. The second console window shows ngspice running on its own. What could be the reason for this?

I noticed that both my versions of xschem and ngspice are different than the ones used in the cloud virtual machine. Could that be the issue?

it will take some time to finish as it scans through entire model files to find nfet and pfet models

I also faced this. Just go to "Simulation->Configure simulator and tools" and change the command running engspice. Mine is for reference "konsole -e 'ngspice -i "$N" -a'", as my favorite terminal is konsole ;-)

The original command uses variable $terminal, which is empty in my case 😉

@Tiago Silva you may try exporting PDK_ROOT in the .bashrc file
