Our target is automation of analog circuit's layout, which is a bottleneck in mixed-signal's design. We formulate the layout explicitly considering manufacturing process, and propose an algorithm that consists of simultaneous expression and optimization of placement and routing. The key is that all the cells and wires are represented by rectangles. The algorithm is combined into a commercial tool, and the performance convinced us that the utilization shortens the design time.
