i'm trying to setup these constraints in design compiler
are there general rules of thumb on how to define T1,...,T6?
i figure that all will be some fraction of the clock period....
but what's a "typical" setting if there is such a thing?
set_clock_uncertainty -setup $T1 MyClock
set_clock_uncertainty -hold $T2 MyClock
set_input_delay -min $T3 -clock MyClock [all_inputs]
set_input_delay -max $T4 -clock MyClock [all_inputs]
set_output_delay -min $T5 -clock MyClock [all_outputs]
set_output_delay -max $T6 -clock MyClock [all_outputs]
