Logical effort based automated transistor width optimization methodology

The paper presents a new automated transistor width optimization methodology for SoC. The methodology is based on Logical Effort theory. The proposed methodology is completely automation based and uses different procedural blocks written in TCL (tool command language). The methodology requires SPICE netlist as input and optimizes transistor widths for minimum delay. Both sequential (flip-flop) and combinational (basic logic gates) logic blocks were optimized successfully using the proposed methodology.
