what is the difference between "port" and "pin" in DC
if there is a output port in the design named " output " are these commands the same ?
[gets_pins output] [gets_ports output]
 

I think ports are the in/out/inout of your design. Pins are the in/out/ of cells of your synthesised design, such as the in or out of an and cell.
 

In DC, "port" only refers to the top module pin names, but "pin" refers to the top modul pin names and submodule pin names. If your design has pin named "output" in some submodule and has port named "output", then the result information of executing [get_pins output] is more detailed than that of executing of [get_ports output]
 
And i think ( i dont know correct or incorrect ) port is collection of pins

Port refers to in,out and inout.......
i.e wire & reg. internal pin for different modules.
As a pin where we can apply the input & get the output in TOPLevel MODULE.
