find the distance from primary inputs and outputs

Hi,

A given net deep within the design may have several primary inputs (PI) in the fan in cone. I want to find out how many nets are between the PI and the target net. Since there are several PI, I will pick the highest distance. 

 

Also, the target net's value propagates to several primary outputs (PO). I want to find the distance of different POs  from that net. 

 

Could anyone kindly provide any suggestions on how to get this using  Tcl in Vivado?

 

Thanks.
