# graham.petley@vlsitechnology.org
# based on scmos.tech27, an original work distributed with the Magic distribution
#
# This technology file has been slimmed down in order to make it simpler and easier
# to understand. Basically, only layers needed for digital standard cells are
# supported (so no fancy analog or high voltage stuff). There is only one style
# for extraction, cifin and cifout: the lambda=1um one.
# The DRC section has the rules updated to vsclib ones (from the original scmos
# rules), but it hasn't been extensively tested, so is likely to miss some of the
# more obscure violations.
#
# Starting from scmos.tech27, make the following changes
#    19-Oct-03
# 1/ Remove poly2 and associated transistor types and contact types (ec, el)
# 2/ Remove via on flat surface rules 8.4 and 8.5
# 3/ Remove all styles from cifoutput section except 1.0(gen) and plot
# 4/ Remove all styles from cifinput except 1.0(gen)
# 5/ Remove all styles from extract except 1.0(scna20_orb)
# 6/ Remove the two versatec plot styles
# 7/ Remove MOSIS rules 11.*, 12.*, 13.*, 19.*
# 8/ Remove capwell and MOSIS rules 17.* and 18.*, CWC CIF layer and cw references
# 9/ Remove highvoltnwell, highvoltpwell and associated diffusions
#10/ Remove capacitor
#11/ Remove bipolar transistor references and MOSIS rules 16.*
#12/ Remove CCD references and MOSIS rules 
#13/ Remove implant plane
#14/ Remove enfet and epfet, nffet and pffet
#15/ Add synonyms polyct, ndifct, pdifct, ntie, ntiect, ptie, ptiect
#16/ Relabel styles to lambda=1um(vsclib)
#    18-Dec-03
#17/ Added support for the abutment box layer, AB (GDS 63)
#18/ Fixed problem with labels over contacts
