how to find Dmin and Dmax

ya ..when we are dealing with wave-pipelining circuit we need to calculate these min and max delay. there will be some output arriving earlier and some output arriving later.. what are those minimum and maximum delays..? For eg. consider any logic with input and output registers.. ; what will be the minimum and maximum propagation delay between those input and ouput registers?

Note: here i want to exclude the pin delay.. ie. from input pin to input reg and from output reg to output pin.

does the tool itself report these report or we need to calculate manually ? if we need to calculate manually wat are the parameters that we can use from tool reporting?
