Creating a power-aware structured ASIC

In an attempt to enable the cost-effective production of low and mid-volume application-specific chips, researchers have proposed a number of so-called structured ASIC architectures. These architectures represent a departure from traditional standard-cell-based ASIC designs in favor of techniques which present more physical and structural regularity. This paper presents circuits which provide power-performance flexibility in this regular, structured ASIC environment. These circuits, which employ gate sizing and voltage scaling for energy efficiency, enable delay-constrained power optimization to be performed for structured ASIC designs.
