# ADDING ADDITIONAL FEATURES TO THE CLOCK_OPT COMMAND
############################################################################################################

## When you want to do interclock delay balancing, you need to execute the following commands :
#  set_inter_clock_delay_options -balance_group "Clk1 Clk2"
#  clock_opt -inter_clock_balance


## When you want to update the IO latency before you start the post CTS optimization, add :
# set_latency_adjustment_options -from_clock  ....  -to_clock .... -latency ....
# clock_opt -update_clock_latency -no_clock_route
