High-Level Area Estimation

Early power estimation requires one to estimate the area (gate count) of a design from a high-level description. We propose a method to do this that makes use of the con-cept of Boolean networks (BN) and introduces an invariant area complexity measure which captures the gate-count re-quirement of a design. The method can be adapted to be used at different points on the area/delay tradeoff curve, with different synthesizer/mapper tools, and different tar-get gate libraries. The area model is experimentally verified and tested using a number of ISCAS and MCNC bench-mark circuits and two different target cell libraries, on two different synthesis systems
