# outside of the standard cell except for the DRC rule for
# FET to diffusion contact spacing (which is 0.05um, not 0.055um)

# Parasitic capacitance values:  Use document (...)
#-------------------------------------------------------------------------
# This uses the new "default" definitions that determine the intervening
# planes from the planeorder stack, take care of the reflexive sideoverlap
# definitions, and generally clean up the section and make it more readable.
#
# Also uses "units microns" statement.  All values are taken from the
# document PEX/xRC/cap_models.  Fringe capacitance values are approximated.
# Units are aF/um^2 for area caps and aF/um for perimeter and sidewall caps.
#-------------------------------------------------------------------------
# Remember that device capacitances to substrate are taken care of by the
# models.  Thus, active and poly definitions ignore all "fet" types.
# fet types are excluded when computing parasitic capacitance to
# active from layers above them because poly is a shield; fet types are
# included for parasitics from layers above to poly.  Resistor types
# should be removed from all parasitic capacitance calculations, or else
# they just create floating caps.  Technically, the capacitance probably
# should be split between the two terminals.  Unsure of the correct model.
