Hello @Stefan Schippers, do you know why it doesn't save the transistor information?

@Juan Andres don’t know if this is a problem or not, but depending on the pdk, the spice mosfet units may already in be in microns. When you set the parameters on the nmos to 1u/0.28u, the spice simulator may process this as 1 picometer/0.28picometer (effectively zero for the simulator). Try w=1 l=0.28. This is just a guess.

No, I haven’t problem for dimension of transistor , I have problem when I want save information of the transistor

The fixed schematic. the syntax for the current is:

i(@m.xm1.m0[id])

to avoid zero length vector errors add

remzerovec

before

write

command.

thanks, is it not possible to get these values ​​like in sky130?

you must save all these parameters explicitly.

I do not understand I made the same changes in my file, but I only get the current
