Abstract:

A robust redistribution layer (RDL) router is required for advanced package designs, where the length-matching constraint for a group of nets needs to be considered to preserve good timing properties at the package level. For area-I/O flip-chip design with pre-assigned nets on RDLs, we propose the first group-based length-matching routing...More
