Hi, don't confuse the Mosis design rules (*SCMOS*) with the TSMC
design rules.  *SCN6*.*.tech27 would be in terms of Mosis rules, so
you could not read TSMC design rule layout with it.

someday (in august ?) there will be a version 2001a set of techfiles
including some support for TSMC design rules, see the CHANGELOG file:

 ftp://ftp.isi.edu/pub/sondeen/magic/new/beta/CHANGELOG

(pretty much limited to viewing layout -- and doing that only crudely.
it's quite hard for magic to handle the small value of lambda, the
large number of layers (requiring their own "planes"), 45 degree
shapes and special/nonlinear design rules, and much different types of
transistors (eg. native) available in those design rules, not to
mention mixed signal stuff like deep wells.

for conventional logic layout, i think SCMOS rules are the way to go,
and you get scalability.

i'm not aware of the 'texture mapping' you're referring to, can you
give me a pointer ?

thanks,
/jeff

PS. also you need to read ftp://ftp.isi.edu/pub/sondeen/magic/new/README
about dealing with those "too many types" errors
