it's kludgy in magic as is, but i think a group is working on
improving bipolar extraction -- i've cc'd this email to their email
list: magic-dev AT csl DOT cornell.edu

here's a note from my alpha/CHANGELOG file:

  (ftp://ftp.isi.edu/pub/sondeen/magic/new/alpha/CHANGELOG)

       added NPN's for SCNA.60 (see SCNA.60.mag, SCNA.60.npn.*, and
       SCNA.60.npnccc.* for examples) and SCNA.00

       note that 'ext2spice' can't really extract an 'npn', but tries
       to find a mos transistor with 4 terminals and a strange gate
       length of 0:

          m0 base base emit coll npn w=28 l=0 ad=0 pd=0 as=0 ps=0
                   ^    ^      ^
                 base  emitter collector
                 node  node    node
             ^
             duplicate base node

        which obviously must be hand-editted to simulate.

        note that if you get the 'Error' node for the collector
        node, it means that you didn't draw the nwell, which is
        required to be drawn for this 'npn' extraction to work.

       draw the 'nwell' over the 'npn' to avoid this 'Error' node:
                            vvvvv

          m0 base base emit Error npn w=28 l=0 ad=0 pd=0 as=0 ps=0
