@Stefan Schippers a quick bug report: we've been using the simulator_commands_shown block here since we have a setup with both Xyce and ngspice but it seems that if you type an unknown name in the 'simulator' field it will generate a '?' in the netlist. We had this happen where someone put 'spice' instead of 'ngspice' as the simulator.

@Roel Jordans The

simulator_commands*.sym

symbols have been updated to handle wrong simulator names (no more ? in netlist). Thanks.

Thanks! That fixed it nicely indeed
