Sumario:As a difference from previous approaches, the approach described in this report starts from the set of partial differential equations governing the dynamics of a pair of coupled RC interconnects, thus capturing the distributed nature of such lines. As it is shown below, the inclusion of a punctual defect (open or short) in any point of the line introduces a new boundary condition to the coupled set of PDEs. By means of a change of variables, this set is decoupled and an analytical solution is found. This solution is further simplified to obtain expressions for the extra delay due to the open/short, which may be useful for the design/test engineers. To validate these results, the report presents a comparison between the analytical solutions and electrical simulation of a pair of coupled interconnects.
