%X New enhanced power/ground mesh structure is presented for voltage drop (IR drop) reduction on power distribution network in integrated circuits (ICs). The new structure focuses on the length of the overall power/ground mesh wire pattern, reducing it by using a complex dotted line wire pattern instead of the usual mesh straps, which brings to wire length reduction on almost 40%, while via count on changed metal layer remained the same. Measurements of the voltage drop prove that with proposed mesh structure IR drop reduced about 76% for power net compared to standard mesh structure but runtime for mesh creation is increased due to more complex patterns. Proposed structure can be used in advanced technology nodes where IR drop phenomenon has become critical for performance of the ICs.
