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.
