Abstract
An integrated circuit has a first and second voltage supply rails with first and second voltage levels and a gated voltage supply rail. Each of the circuit elements is connected either between the first and second voltage supply rails or between the gated rail and the second voltage rail. A source circuit structure comprising one or more circuit elements provides an input signal maintained at a static value during a power gated mode of operation. At least one recipient circuit structure requires receipt of the input signal at the static value during the power gated mode of operation. A distribution network comprises a first subset of circuit elements which pull their output to the first voltage level then the input signal has the static value, and a second subset of circuit elements which pull their output to the second voltage level when the input signal has the static value.
