Abstract: An integrated circuit 2 is formed with standard-cell power conductors 14 which are overlaid by power grid conductors 20. The power grid conductors are offset in a direction transverse to the longitudinal axis of the power grid conductors relative to their underlying standard-cell power conductor. This has the effect of increasing the conductor spacing possible to one side of the power grid conductor. Accordingly, a wider than minimum width power grid conductor may be provided which blocks only one of its adjacent track positions from being used by a routing conductor 22.
