Synthesis and placement flow for gain-based programmable regular fabrics

In this paper we present the Gain-based Logic Block Array (GLA), a new via-programmable regular fabric. GLA is an array of Gainbased Logic Blocks (GLBs). The GLB is a semi-universal logic block designed based on logical effort theory[12]. Customization of the GLBs is provided by programmable vias. To achieve the best performance, appropriate fabric has to be selected from a family of GLAs with different performance-area trade-offs. We describe a synthesis and placement flow which, for a given design to be implemented, allows us to select the best GLA from the candidate family.
