We at UNC-CH are using magic (from Berkeley) as part of a silicon
compiler project.  We have encountered a problem with the way that
magic handles labels when reading scmos CIF.  Magic has trouble
assigning labels when a magic layer corresponds to more than one CIF
layer.  The standard cmos technology files for some time have
guarenteed that no labels will be assigned directly to ndiff.  Instead
they go to the pwell by default after being assigned to space.  This
makes it tough to label drains of transistors.

Does anyone have a technology file for scmos that properly handles
labels on ndiff?  Is this a problem with magic for which there is no
easy work around?

Thanks for your help - Mark Davis (davis@unc.csnet-relay)
