Abstract: A method includes calculating a maximum value of an on-die decoupling capacitor for an integrated circuit (IC) design based on a switching current defined by a number of simultaneously switching bits for the IC design. The method also includes calculating a total decoupling capacitance value offered by spacer cells in the IC design. The method further includes determining an optimal on-die decoupling capacitance value for the IC design as a function of the maximum value of the on-die decoupling capacitor and the total decoupling capacitance value offered by the spacer cells.

Abstract: Systems and methods for selecting die and package parasitic for an input-output (IO) power domain are described. In one embodiment, the method includes determining a minimum on-die decoupling capacitance based at least in part on a product of a number of simultaneously switching IOs of the die and a maximum instantaneous current of an IO; determining a maximum package inductance based at least in part on a maximum operating frequency of an IC and a target impedance of a power delivery network of the die, the IC package, and a printed circuit board (PCB); and determining a maximum die resistance based at least in part on preventing the maximum die resistance from exceeding a maximum static IR drop of the die.

Abstract: A method includes, for an N-bit system on chip (SoC), calculating a minimum number of bits NP that can simultaneously switch without producing an error across a complete warranty time period of the N-bit SoC. The method also includes carrying out power estimation calculations for the N-bit SoC using the calculated minimum number of bits NP.
