􀂊Ever-increasing complex manufacturing constraints
􀁺Design rules, DFM rules
􀂊Increasing analog contents
􀁺Growing number of mixed-signal (digital and analog) designs
􀁺Increasing design size
􀂊Analog layout is still generated at device level
􀁺Need free-form to meet analog layout constraints
􀁺Can tools enable the automation designers want?
•Many failed attempts in the past
