Xilinx

This tree contains Xilinx-specific RTL wrappers, primitive integrations, and helper IP used by SURF.

Layout

• Family folders such as 7Series/, Virtex5/, UltraScale/, UltraScale+/, and Versal/ hold family-specific wrappers and primitive integrations.
• general/ contains Xilinx helpers that are not tied to a single family directory.
• xvc-udp/ contains Xilinx Virtual Cable over UDP support and has its own README.md.
• dummy/ contains placeholder or compatibility support used by build flows.

Keep Xilinx primitive details isolated here or in explicitly family-named subdirectories of a subsystem. When a generic SURF wrapper exists, use it from higher-level RTL instead of instantiating primitives directly.
