Example
## Specify the required minimum and maximum output
## delays on the output pin named "opin" relative to
## the rising edge of the reference clock named "clk1"
set_output_delay 2ns -to "opin" -clk_ref "clk1"
## Or, equivalently,
set_output_delay 2ns -to "opin" -clk_ref "clk1" -min -max
## Specify the required minimum output delay on
## the output pin named "opin" relative to the
## falling edge of the reference clock named "clk1"
set_output_delay 2ns -to "opin" -clk_ref "clk1" -min -clock_fall
## Specify the required maximum output delay on
## output pins with names that start with "o"
## except those that start with "obus"
