This paper details the design and implementation of an asynchronous 3D-NoC router using a novel serialization scheme in the vertical directions which targets 3D production oriented processes. A study of the router cost has been conducted for medium and high density TSVs on 65nm and 32nm nodes. A router integrating the serial link has been implemented in 65nm using medium density TSVs. The serial link provides a throughput of 16 Gb/s for an area gain of 57%, and an additional cost of one NoC routing hop in latency and in energy.
