Signal Integrity Analysis and Channel Reach Extension for a PCIe 3.0 Digital Interface using CST Studio and Altium Designer

This paper introduces an innovative methodology for evaluating signal integrity in PCIe Gen 3 systems by extending the transmission path through the integration of an extension board. A systematic workflow is presented, encompassing both simulation and measurement techniques, to guarantee robust high-speed data transmission. The findings offer critical insights and practical recommendations for engineers engaged in similar applications, with a primary focus on preserving signal integrity in next-generation PCIe interfaces.
