Abstract: An integrated circuit is provided with interface circuitry used to provide an interface between functional circuitry of the integrated circuit and components external to the integrated circuit. The interface circuitry includes a plurality of interface cells having interface components configured to operate from a first power supply. Each interface cell incorporates a power supply line section extending across its width and configured to cooperate with power supply line sections of other interface cells to provide a power supply line structure shared by the plurality of interface cells, for provision of the first power supply to the interface components. Each power supply line section includes a first supply line portion and a second supply line portion, the first supply line portion being sized to support a current carrying constraint of the interface circuitry, whilst the second supply line portion is sized insufficiently to support that current carrying constraint. Instead, each interface cell is arranged within the interface circuitry such that the second supply line portion is connected to a current carrying structure external to that interface cell, such that the second supply line portion in combination with the connected current carrying structure is sized sufficiently to support the current carrying constraint. Such an approach enables a reduction in the area required for the power supply line structure, hence enabling a reduction in the size of the interface circuitry, and accordingly a corresponding reduction in the required size of the integrated circuit.

Abstract: An integrated circuit is provided with interface circuitry used to provide an interface between functional circuitry of the integrated circuit and components external to the integrated circuit. The functional circuitry is configured to operate from a first power supply and has a power supply distribution network associated therewith providing the first power supply to the functional components of the functional circuitry. The interface comprises a plurality of interface cells that have interface components operating from a second power supply different to the first power supply. A power supply line structure is shared by the plurality of interface cells, and arranged to provide the second power supply to the interface components. In addition, at least a subset of the interface cells include additional interface components that operate from the first power supply. Each such interface cell is arranged to have independent connection to the power supply distribution network in order to receive the first power supply. This avoids the need to incorporate any lines within the power supply line structure for provision of the first power supply to such additional interface components.

Abstract: Various implementations described herein are directed to a circuit for translating an input signal from a source voltage domain to an output signal for a destination voltage domain that is is different than the source voltage domain. The circuit may include a level shifting portion configured to operate with a supply voltage that exceeds a stressing threshold of one or more components within the circuit. The level shifting portion may be configured to generate the output signal for the destination voltage domain based on the input signal and a power management signal. The circuit may include an isolating portion configured to isolate the one or more components from the supply voltage during activation and deactivation of the circuit based on the power management signal.
