# all55Constructs01 testcase
#
# To cover the full syntax but keep the file size to a minimum,
# the first object of each type (eg cut-layer, metal-layer etc.)
# covers every attribute, and any following objects of the same type
# cover only attributes with different (enum-)values
# that could not be covered in the first object.
#
# Definitions
# - "whole correct syntax covered" means all possible enum values for 
#   attributes are covered.
# - "one correct syntax covered" means NOT all enum values for attributes
#   are covered (usually means that construct can be used only once in a LEF)
#
# version : one correct syntax
# names case sensitive : one correct syntax
# no wire extension : one correct syntax
# bus bit characters : one correct syntax
# divider character : one correct syntax
# units : one correct syntax
# manufacturing grid : whole correct syntax
# use min spacing : two correct syntaxes
# clearance measure : one correct syntax
# property definitions : whole correct syntax covered
# antenna size : only 5.4 syntax covered
# layer masterslice : whole correct syntax covered
# layer overlap : whole correct syntax covered
# layer cut : several statements covering whole correct syntax
#             (all attributes values)
#             CUT01, CUT12, CA
#             other cut layer names used for via...
# layer routing : several statements covering whole correct syntax
#                 (all attributes values) except an old antenna attribute
#                 RX, PC, M1
#                 other routing layer names used for via...
# maxviastack : one correct syntax with range attribute
# via : several statements covering whole correct syntax
# via rule : two statements covering whole correct syntax
# via rule generate : two statements covering whole correct syntax
# nondefault rule : whole correct syntax covered
# crosstalk : whole correct syntax covered
# same-net spacing : whole correct syntax covered
# min feature : whole correct syntax covered
# dielectric : whole correct syntax covered
# irdrop : whole correct syntax covered
# site : several statements covering whole syntax (all attributes values)
