propagation delay

How to find the overall value of a circuit's propagation delay.A circuit having multiple inputs and outputs? I am using quartus 2 10.1 web edition.

If you just want to find out what the propagation delay is from an input(s) to an output(s) (assuming combinatorial logic only), then in TimeQuest you can use the following command:

report_path -from <inputs> -to <outputs>

If you want to actually constrain these paths, then use the set_max_delay and set_min_delay SDC constraints.
