We assume that long wires represent large capacitive loads, and investigate the effect on the area of a VLSI layout when drivers are introduced along many long wires in the layout. We present a layout for which the introduction of drivers along long wires squares the area of the layout; we show, however, that the increase in area is never greater than this, if the driver can be laid out in a square region. We also show an area-time trade-off for a single long wire by which we can reduce the area of its driver to Θ(lq), q
