Recently RDLs (Re-Distribution Layers) and micro-bumps are widely adopted in 3D IC designs. In this research, a sorting-based micro-bump assignment method is proposed. The approach initially assigns the I/O pads to micro-bumps by sorting the Manhattan distance between them. Then single layer routing in two RDLs are carried out respectively. The experimental results show that the proposed method is able to obtain the routes with shorter total wire length in reasonable CPU times.
