Zusammenfassung: | 1. Technical Field
A method and a related program storage product for adding decoupling capacitance in an integrated circuit during the floor planning stage of the integrated circuit design. The invention overlay a power grid on the floor plan and then divides the power grid into regions or macros. For each region or macro, a support decoupling capacitance value required to support a voltage of the power grid and a native capacitance value are determined. Based on those values, a required decoupling capacitance value along with its decoupling capacitance area is determined. The design is then alternated based on the decoupling capacitance area. |
