Abstract

Tightly matched signal propagation and strong crosstalk protection are key requirements for next-generation NoC links featuring GALS synchronization and low-swing signaling. In this paper, we present a new methodology for NoC global link routing which addresses these challenges. Our approach creates bundled link routes with geometrically matched wires, thus leading to much reduced intra-link variations. Moreover, our link router supports high-regularity wire spacing and shielding strategies. Delay variation among different wires of a link is 25% to 70% lower than what can be achieved using a state-of-the-art timing-driven global routing flow. Additionally, crosstalk effects are reduced by more than 30%.
