This thesis breaks up the traditional constraints of Channel Model

builds a new layout model-superplane model. The new model can explore the nature of multilayer layout better than ever. Based on this new nodel

the routing has been studied emphatically and the superplane routing algorithm has been created simultaneously. The "rode" technique has been proposed for solving the net order very successfully and all nets can be routed parallely. By directly aiming at the minimum number of routing layer and via dynamically distinguishing the related position of nets

and with global view of releasing the unreasonable resources owned by net

iteration has been avoided in the routing and precise results have been obtained efficiently.
