Hello. I'm using xschem & ngspice as the below picture. I want to look at parameters and characteristics of mosfet. but "display all" command doesn't show my mosfet. @Akira Tsuchiya mentioned about this problem but is there any solution? picture #2 is the screenshot of youtube tutorial of SKY130(

https://www.youtube.com/watch?v=YUA_I55k-tM

). He commanded "display all" and it showed the mosfet. I think there is a difference between gf180mcu and sky130
I want to get Vth, Gm, Cgg ... etc. of mosfet

You can try the command "listing e" after the netlist has been loaded in ngspice, to see a list of all the device names. Then, depending on the name of the device, you can add a line like "show m.xm1.m0" or "print @m.xm1.m0[gm]" to your netlist (within a control block, between ".control" and ".endc") and run it. Alternatively, you can add the line "show all" to your netlist to see the operating point information of all devices.
