Abstract

This chapter presents a new methodology to enhance the optimization process of an analog integrated circuit synthesis tool, AIDA-C, by taking into account the floorplan of the circuit. The addition of the new Analog Module Generator (AMG) in the AIDA framework creates the possibility to efficiently explore the circuit floorplan during the optimization process and to improve the quality of the final floorplan by adding complex device structures enhancing the layout matching, symmetry, and routing, reducing some of the non-idealities to which analog integrated circuits are so sensitive. The performance enhancement attained with AMG is demonstrated using a well-known benchmark circuit, optimized by AIDA-C with and without taking into account AMG's complex structures in the evaluation of the circuit's floorplan.
