Placement with symmetry constraints for analog layout design using TCG-S
In order to handle device matching for analog circuits, some pairs of modules need to be placed symmetrically with respect to a common axis. In this paper, we deal with the module...

Placement with symmetry constraints for analog layout using red-black trees
– 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 unfeas...

Block placement with symmetry constraints based on the O-tree non-slicing representation
The ordered tree (O-tree) representation has recently gained much interest in layout design automation. Different from previous topological representations of non-slicing floorpl...
