Each such connected cluster forms one merged polygon. The merged polygon will appear at the lowest possible level in the hierarchy at which all constituents are known. -I added a small sample P&R block (thanks to Jean-Paul Chaput for allowing me to use it) into the project. This block has about 8k standard cells. The design rules are symbolic 1µm rules, but the hierarchy is realistic. +I added a small sample P&R block into the project. Thanks to Jean-Paul Chaput for allowing me to use it. This block has about 8k standard cells. The design rules are symbolic 1µm rules, but the hierarchy is realistic. Place-and-route blocks have a hierarchical structure of standard cells, sometimes also via cells or tie-down diodes. The routine usually is within the top cell of the block and a flat arrangement of metal wires (paths, polygons) and vias rectangles (unless these are cells on their own).
