# FirstEncounter(TM) Clock Synthesis Technology File Format
#

#
# This is an example file, adapt it for your design !!!
#
# IMPORTANT: Existing buffers/inverters on the clock network(s) are NOT automatically
# removed during clock tree synthesis, so to get a nicely balanced tree you should 
# do this manually by running the command "deleteClockTree -all".
# To remove an already inserted tree, "changeClockStatus -all -noFixedBuffers"
# has to be run beforehand, otherwise the buffers can not be removed as they have
# the status "FIXED".

# clock tree  (tight constraints)
#
# For (very) small trees "MaxFanout" might be useful to get 
# some more buffers and reduce the impact of (clock tree)
# routing.
#
# For the best results (but worse overall routability) the clock
# net can be routed during CTS ("RouteClkNet  YES"). To get an
# optimally balanced routing also set "UseCTSRouteGuide YES".
