Abstract

In this paper, we discuss power reduction by comparing two different design techniques targeting low-power ASICs: clustered voltage scaling (CVS) and gate resizing. The CVS is a technique to reduce supply voltage partially, allowing to reduce power without performance degradation. As a result of applying to real gate-array circuits, the CVS reduced power by 30-60% even at dominant wire capacitance, while the gate re-sizing got less effective. The CVS is considered to be a key technique toward deep sub-micron age, in which the wire capacitance will be further dominant.
