The propagation constant and rise time of High-Tc superconducting interconnect for VLSI packaging are calculated and simulated by using a generalized two-fluid model and transmission line theory.Meanwhile
the temperature dependences of attenuation constant and phase velocity as well as the rise time based on the generalized two-fluid model are compared with those based on conventional two-fluid model.The limitation of the later is indicated.Our results could be used in the VLSI system CAD.
