This paper presents SANGRIA, a tool for automated globally reliable variation-aware sizing of analog integrated circuits. Its keys to efficient search are adaptive response surface modeling, and a new concept, structural homotopy. Structural homotopy embeds homotopy-style objective function tightening into the search state's structure, not dynamics. Searches at several different levels are conducted simultaneously: The loosest level does nominal dc simulation, and tighter levels add more… CONTINUE READING
