Routing density is becoming in big challenge in die-to-die interconnects. In this paper, we propose use of the dual-stripline configuration for routing signals in high-density interconnects. The scheme can improve the routing density by up to 33% when compared with the conventionally used stripline configuration. To address the challenges of crosstalk due to the proximity between vertically adjacent signal lines, halfpitch offset between lines on vertically adjacent layers has been proposed. The proposed routing scheme has been validated using 3D full-wave electromagnetic simulations. The simulations show that the scheme can be used for increasing the routing density in the Bunch-of-wires interface by 25%, while meeting all the Bunch-of-wires channel specifications, which include eye-opening value above 60% unit interval at a bit error rate of 10⁻¹⁵, with data rates of 16 Gbps per wire.
