I have been trying to generate the SPICE deck for some GaAs circuits
layed out using Magic. I had previously posted here and had been adviced
to use ext2spice instead of sim2spice. However, I am having problems with
the deck that ext2spice generates. Here are some of my problems:

1. The devices generated are MOSFETs and mot MESFETs.
   What should I do? Just change the device line to correspond to
   the MESFET line?
2. Capacitance values are too large. 
3. Schottky diodes appear as MOSFETs with their drain and source tied together.

If I have to change the generated file so much for it to describe
my circuit, what is the advantage of using ext2spice over generating the
deck manually?

Thanks,
Blanca
