Overshoot and undershoot control for transmission line interconnects

In this paper, properties of overshoot and undershoot as functions of circuit parameters are formally investigated. We identified existence conditions of overshoot and undershoot. Analytic solutions of overshoot and undershoot amplitudes by line length, termination, and rise time are derived. These analytic solutions have a form of two-piece linear dependence of these amplitudes on interconnect length. Simulation results for lossy pin-to-pin and daisy-chain interconnects demonstrated this dependence even with loss effects present. The role of interconnect length in the control of overshoot and undershoot at the physical design step is investigated.
