The traditional way of approaching placement problems in computer aided design cad tools for analog layout is to explore an extremely large search space of feasible or unfeasible placement. Analog layout synthesis a survey of topological approaches edited by helmut e graeb analog components appear on 75 of all chips and cause 40 of the design effort and 50 of the re designs due to increasing functional complexity of systems on chip the difficulties in analog design and the lack of design automation support for analog . Analog layout synthesis a survey of topological approaches edited by helmut e graeb analog components appear on 75 of all chips and cause 40 of the design effort and 50 of the re designs due to increasing functional complexity of systems on chip the difficulties in analog design and the lack of design automation support for analog circuits make analog components a bottleneck in chip .
