ABSTRACT:
A method for preprocessing tie net routing data organizes the data into a plurality of tie nets each based on an optimal connection path between a pin or set of pins and the power grid. The router then routs the data embodying the thusly-simplified plurality of tie nets. Once the routing is complete, post processor takes the routed design and returns it to its original net list state while keeping the routing solution.
