This paper proposes a function-generation based area-aware Configurable Logic Block (CLB) architecture and an associated packing technique, for SRAM-based FPGAs. The new CLB architecture provides the same logic functionality, but occupies 38% less area, consumes 38.37% less power and requires 50% less configuration-bits per CLB when compared to the standard 4-LUT CLB architecture. The proposed packing technique is timing-driven and is shown to produce designs with almost same routing cost and performance overhead as that produced by the T-VPack algorithm on standard benchmark circuits.
