Abstract: There is disclosed a switching arrangement comprising a switch with a plurality of individually controllable elementary switches connected in parallel between a first supply rail and a second supply rail. Each of the elementary switches can be in either one of a closed state and an open state independently of the others. A controller is adapted to dynamically control the closing or opening of the elementary switches, depending on the intensity of a current flowing through the switch. The number of elementary switches in the closed state is variable. The higher is the intensity of the current, the higher the number of elementary switches in the closed state. Thus, the impedance of the switch decreases when the current increases, and vice versa, and the voltage drop across the switch may be kept substantially constant.

Abstract: A method is provided for optimising cell variant selection within a design process for an integrated circuit device. The method comprises performing cell placement and signal routing for an integrated circuit being designed using default cell layout information for cell variants of at least one cell type. The method further comprises performing cell variant optimization comprising identifying at least one cell of the at least one cell type to be substituted and substituting a default cell variant of the at least one identified cell with an alternative variant of the at least one identified cell. The method further comprises, during cell optimization, configuring a pin interconnect modification for mapping at least one pin location of the alternative variant of the at least one identified cell to at least one pin contact for the default cell layout.
