Abstract
For air-bridges running orthogonally to the channel, a detailed routing of the interconnect lines is performed. A post expansion is then performed to spread existing lines by adding more tracks if required for support posts. The interconnect lines are then scanned to determine post placements. For air-bridges running parallel to the channel, empty post positions are determined and aligned to optimize the distance between positions. Detailed routing is then performed and the lines are scanned to determine post placement. Finally, cell rows and interconnects are compacted.
