Hi All,

How usage in different cost groups may help to meet timing in synthesis? Could you please provide examples?

Thank you!
 

Its a simple and old traditional technique of divide and conquer.

Its like timing critical paths further bucketed into more smaller groups terms as cost groups. Once these buclets are created the tool could be any industry standard tool is able to focus better and help achieve PPA closure.

What is PPA?

How the cost groups should be defined?

Is this something like following?
%> create_group find_cell{cellA,cellB,...}
 

Power Performance Area

I think now is the good time to look at the product documentation .. for syntactical help
It will vary from product to product
