critical path minimisation

[paulki]

In case of combo-full adder (3 FA are connected in serially, each having 10ns delay) the result should be updated in every 10ns. How can i minimise the critical path here ???

u can pipeline the critical path,

The pipleline of the cirtitcal path can be done by inserting flipflop between each FA, Due to this the critical path is borken and each path will have 10ns.

Yes, pipeline is a choice, or you could imply a parrel full adder

if you want to update result for every 10 ns you can go for pipeline.......... but look out for latency and through put
