FPGA hands-on content spans interface implementation, timing closure and embedded co-design, emphasizing reusable code and flows. Per fpga.love industry news: PCIe 3.0 high-speed interface design: timing to drivers.

Start with a minimal verification environment and official docs, then extend incrementally with community cases. Follow our monthly issue and video modules for deeper coverage.

Protocol Layers & Link

PCIe is layered: the transaction layer organizes packets, the data link layer ensures reliable delivery, and the physical layer runs the serial differential link. First complete link training and BAR setup, then drive DMA channels, with timing constraints covering all high-speed transceivers.
