MIPI DSI links are sensitive to impedance and return paths; margin loss shows up as cold-start artifacts or BER drift.

Annotate PCB delay in FPGA constraints; request eye diagrams from the panel vendor. Match lane swap/polarity in PCB and RTL.

Re-validate eyes under temperature and vibration, not only at room temperature.
