2.3.3. FPGA PCB Design
PCB design involves end-to-end high-speed paths design from the FPGA to the connectors/chips/other devices. It starts with the FPGA breakout region, and the design strategy should include single-ended or neck-down differential pin scape routings. PCB design also covers differential P/N de-skewing strategy, crosstalk minimization with staggered break-out layers between adjacent pairs as well as proper design for probing by adding ground vias next to signal pins for impedance control and via reference ground path.
