Abstract: A semiconductor power network (100) decoupling capacitance (decap) budgeting problem is co-optimized with a wiring enhancement problem, wherein the solution is formulated to minimize the total decap to be added or wiring changes (addition of wires (420)) to be made to the network (100). Voltage constraints, available white space and other constraints determine the amount of decap to be added. Wire enhancements and/or added decap can be distributed throughout a violation region (120) of the semiconductor circuit (100) design to reduce dynamic supply voltage noise so that dynamic network voltages are at all times maintained greater than a user-specified threshold voltage level (220).

Abstract: A semiconductor power network decoupling capacitance (decap) budgeting problem is formulated to minimize the total decap to be added to the network subject to voltage constraints on the network nodes of a semiconductor circuit design. Voltage constraints on the decap to be added are taken into consideration such that the decap can be distributed throughout a hot spot region of the semiconductor circuit design and not be limited to placement at a single location in the circuit. Dynamic network voltages are at all times maintained greater than a user-specified threshold voltage level.
