Hi , I am trying to run basic run to obtain parameters of the MOSFET. Here, I try to plot id vs vds curve, its not automatically opening as in case of examples, I need to plot it in command window to obtain it. Also how to save transistor parameter value. I tried to save it , but I am unable to view it. I think my syntax is wrong. can anyone help on this 2. Also I am unable to find .raw file in the simulation directory. where will it be there

the second write command is useless since there is no analysis (op/dc/tran/ac) beforehand. The save command for transistro gm is incorrect:
save @m.xm1.msky130_fd_pr__nfet_01v8_lvt[gm]
is probably the right command. After the .temp command add also a:
.options savecurrents
so all mos currents will be saved (drain, source, etc). To find where the raw file is located do this at the xschem terminal prompt:
puts $netlist_dir
it will tell you the directory where the raw file is saved.

how to find the saved data, like gm of transistor. Can it be directly printed in the terminal window,
s
If you do a
print @m.xm1.msky130_fd_pr__nfet_01v8_lvt[gm]
the value will be printed on the terminal
