Understanding the Technical Features of StarRC Merge Corners

Traditionally parasitic extraction tools apply single process corner variation to the entire design and designer will run various process corners to do complete sanity check on the design. With advanced nodes the margins for design are reducing and to identify your worst-case process corner requires some flexibility on part of the parasitic extraction tool. StarRC Merge Corners feature provides the necessary flexibility to the designer so that different process corners can be assigned to different sections of the same design. Yet another feature from StarRC to provide more control to the designer during design phase.
