Hi all While simulate in xschem I'm getting bash: line 1: ngspice: command not found

have you installed ngspice tool?

Yes

Is it in your

$PATH

? Try with

which ngspice

, that should yield something like

/usr/bin/ngspice

.

You can specify the full path of ngspice if it is not in the PATH list of directories: Click 'Simulation->Configure simulators and tools' and set the full path of ngspice, see example below on my system. set the path according to your specific install.
