[Magic-dev] ext2sim, ext2spice unexpected behavior

Hey Chris, I had the exact same problem, and I have compiled magic7.4
under a variety of different platforms.  The solution that I found was
to use the "exttospice" command from within magic in the tcl version.
I have a script that does this (so that it looks like the old
"ext2spice" command-line command) if you are interested.  Using this I
was able to get non-zero area and perim values for the spice deck.
BTW in my experience the built-in "exttospice" in the tcl version is
*much* faster than the old command line version.

I can't help you with the ext2sim stuff, although I have also written
scripts that walk the .ext files and determine all of the aliases for
every node (not sure if that's what you need or not).
