I tr= ied that as well. Does not work. Perhaps my transistor model is bad. I will= try to follow the example shown on geda:ngspice:

geda:ngs= pice_and_gschem [gEDA Project Wiki]

and see wheth= er it compiles.

Hello,

If you look at the generated netlist, the device still= starts using the letter =E2=80=98M=E2=80=99 not the X. So ngspice looks fo= r a MOS transistor instead of the subcircuit.

AFAIK, to really fix the problem you should check the value of the att= ribute =E2=80=9Cdevice" on the symbol. It should be SUBCKT_PMOS or SUBCKT_N= MOS instead of PMOS_TRANSISTOR or NMOS_TRANSISTOR. Then, the spice-sdb back= end should generate the correct device line.

Hello John,

To my knowledge, if you use a SUBCKT the component in question should have a X? as a refdes.

Don't know what will happen if the name of the SUBCKT is the same as a MODEL name inside the SUBCKT, never tried it.

Merry Christmas,
Robert Zeegers.
