In current chip and package designs, it is a bottleneck to simultaneously optimize both pin assignment and pin routing for different design domains (chip, package, and board). Usually the whole process costs a huge manual effort and multiple iterations thus reducing profit margin. Therefore, we propose a fast heuristic chip-package co-design algorithm in order to automatically obtain a bump assignment...
Due to the advantage of flip-chip design in power distribution but controversial peripheral IO placement in lower design cost, redistribution layer (RDL) is usually used for such interconnection. Sometimes RDL is so congested that the capacity for routing is insufficient. Routing therefore cannot be completed within a single layer even for manual routing. Although [2] proposed a routing algorithm...
