    摘要: Disclosed is a computer-implemented method to generate a placement for a plurality of device modules within an analog integrated circuit (IC) subject to a set of constraints. By building a constraint hierarchy tree according to the constraints, conflicts of constraints can be identified and resolved. Furthermore, placements can be generated based on the hierarchy tree through a bottom-to-top dimension optimization process and a top-down wire length optimization process. Furthermore, a graphical user interface can be used to display the tree, and the user can edit the tree visually and interactively.
