Dear Krishnan,

   You want to use "ext2spice".  I have a hunch that your problem is
that you are using the "extresis" command to generate resistances for
your simulation, and following tutorial #8, there are instructions
which refer to using ext2sim but don't mention how to get spice
output.  There is a man page for "ext2spice" (and ext2sim) which should
have been installed along with magic, but I'm guessing that you already
know that.

   "extresis" requires generating a ".sim" file to make it work properly.
However, the ".sim" file is only needed to back-annotate the ".ext"
files.  So after "extresis" has done its work, all the appropriate
resistance information is in the ".ext" files, and the "ext2spice"
command will reproduce those resistances faithfully in the spice output.

   Follow the example of magic tutorial #8 but replace the very last
command ("ext2sim -R -t! -t# tut8r.2") with "ext2spice".  Be sure to use
the switch "-f spice3" for spice3 compatibility.  If I recall correctly,
ext2sim and ext2spice take many of the same options, so I think for the
tutorial you would want to do "ext2spice -f spice3 -R -t! -t# tut8r.2".
