Expert Guided Analog Layout Placement and Routing Automation for Deep Nanotechnologies

Abstract

This paper presents a new analog layout design tool for placement and routing of circuits using innovative template algorithm to decrease the solution space in an effective way then an optimization method to choose the best placement using satisfiability modulo theories SMT linear Solver. This tool is built in a way to consider the most advanced techniques used in today`s industrial products as well today advanced deep nodes to decrease the design cycle and layout iterations. This tool extracts the main sub-blocks types from the schematics then starts processing on each sub-block alone to find the best matching pattern that satisfies the block constraints and estimate the needed routing taking the parasitic into consideration, then using the SMT solver to find the best area to fit the design.
