Automatic routing method for inter-functional cells
摘要:
In a semiconductor integrated circuit including a plurality of functional cells, it is determined whether or not each of the functional cells includes terminals to be electrically connected to each other. If a functional cell includes one of such terminals, a preset routing prohibiting area is set in the functional cell. If a functional cell does not include any of such terminals, a routing prohibiting area is set in the entirety of the functional cell. Then, routing between the terminals is carried out in accordance with the routing prohibiting areas.
