Conclusion
As PCIe has advanced from one generation to the next, it has transcended from a PC-only interface to a staple
in most embedded architectures. Its ability to scale from simple control loops to massive AI workloads while
maintaining software compatibility is unmatched in the industry. As this eBook reveals, PCIe's versatility allows
designers to consolidate legacy interfaces, facilitate heterogeneous computing, and extend system reach with a
single, unified fabric.
However, the transition to higher speeds, specifically the jump to PAM4 signaling and PCIe 7.0 capabilities, brings
a new level of design rigor. The margin for error in signal integrity is shrinking, making the physical implementation
just as important as the silicon itself.
PCIe design success now requires a holistic engineering approach. It will require a robust ecosystem in which
advanced switching and retiming silicon works in tandem with precision interconnects and signal-integrity
expertise. By working closely with leaders like Microchip and Samtec, engineers can navigate new PCIe challenges
with confidence that their embedded designs will stay robust, scalable, and future-ready.
