[comp.lsi.cad] Magic Extraction Bug Fixes

dcs@portia.Stanford.EDU (don stark) (12/19/90)

I fixed a few of the bugs people have reported in the extraction parts of
magic.  Patches are available via anonymous ftp from gatekeeper.dec.com
(16.1.0.2).  The patches are in /pub/DEC/magic. The new ones are:

note.13: fixes bug in extflat-ext2sim that caused lumped resistors to
         not be produced.

note.14: fixes bug in resistance extractor that caused coredump.

note.15: contains updated version of scmos.tech that includes the 
         "fetresist" lines and gscap and gccap values that the 
	 resistance extractor uses.  I only modified the extract
	 styles lambda=1.0 and lambda=1.5; the values I used came 
	 from our rsim parameter files. Since the effective fet 
	 resistance depends strongly on the process, I strongly urge
	 you to change these values to match your device models.
	 Page 35 of Magic Maintainer's Manual #2 describes how to do 
	 this.

In the rush to get the final distribution ready, it looks like
some last-minute bug fixes got included that were more bug than fix. 
Sigh.
