Abstract :
We present a new and innovative logic synthesis approach using regularity information of a design to selectively apply transformations and globally guide the synthesis process. Since traditional logic synthesis applies transformations without consideration of global design characteristics such as regularity and dataflow, it destroys a substantial amount of regular structures. In addition, due to the non-incremental nature of most logic transformations, synthesis relies vastly on the computationally expensive concept of trial and error application of transformations, a time-consuming process in the synthesis of large designs. The proposed approach addresses both shortcomings of traditional logic synthesis and describes a mechanism to speed up logic synthesis and preserve regularity. It selectively applies transformations to places with similar characteristics and to the same stage of a regular structure, introducing a notion of dataflow-aware synthesis. Preservation of regular structures has tremendous advantages to the following physical design stages. It yields high-density layouts, shorter wiring length and improved delay. In addition, the layout becomes more predictable at an earlier design stage.
