Physical-based Modeling and Fast Simulation of Wireline Links

To efficiently exploit the performance of wireline channels and alleviate the computation time due to the large amounts of simulation, this paper proposes a physical-based modeling mechanism for the performance studies of electrical links on multilayered printed circuit boards (PCBs). Our mechanism includes: 1) using a physical-based method to achieve high-speed and high precision simulation; and 2) combining configurable parameters and intermediate data of simulation to simplify evaluation process and support parameters sweeping. Experimental results show a good correlation with full-wave method up to 40 GHz and a significant acceleration in computation time of at least two orders of magnitude. Cooperating with system simulator, our approach also gives a good assistance in PCB channel design for high-speed interconnect systems.
