One of the toughest challenges in architecting a state-of-the-art system is knowing—before prototypes are built—that the system will achieve robust high-speed performance on all channels and across environmental conditions. Due to the fast data rate and high-volume nature of its end-equipment PCIe 5.0 presents a unique challenge for system implementers. To maintain control over certain systems costs and/or enable their smooth operation at highest data rates, the usage of Retimers becomes paramount. This paper presents a how-to design guide for common PCIe topologies involving Root Complex, Retimer, and End Point.
This presentation provides a how-to guide for analyzing and optimizing PCI Express 5.0 interconnects with Retimers using an EDA simulation flow and system design best practices. Common PCIe system topology examples are provided, and a start-to-finish analysis methodology is proposed including placement, material selection, and simulation.
Basic familiarity with signal integrity concepts (insertion loss, crosstalk, reflections, etc.), IBIS-AMI simulations (s-parameters, model parameters, etc.), and Retimers
