Use X-ray inspection to verify void percentage. Ensure power sequencing matches FPGA datasheet requirements (typically core voltage before I\/O banks).<\/p>\n\n\n\n<p><strong>Q2: How to resolve signal integrity issues in 10Gbps+ transceiver channels?<\/strong><br>A2: Route differential pairs with &lt;5mil length mismatch and insert ground-stitching vias every 150mil near SerDes lanes. Simulate with IBIS-AMI models to validate eye diagram margins pre-production.<\/p>\n\n\n\n<p><strong>Q3: Why do we encounter timing closure failures despite meeting constraints?<\/strong><br>A3: Clock skew often originates from unequal via counts in global clock trees. Balance H-tree routing with matched via transitions (typically 8 vias per branch). Add programmable delay buffers for \u00b150ps fine-tuning.<\/p>\n\n\n\n<p><strong>Q4: What causes thermal runaway in high-density FPGA designs?<\/strong><br>A4: Inadequate copper thickness in power planes (recommend 2oz for >15A currents). Implement thermal relief patterns under BGA with 0.3mm diameter voids. Monitor junction temperature using on-die sensors via I2C.<\/p>\n\n\n\n<p><strong>Q5: How to mitigate EMI from high-speed memory interfaces?<\/strong><br>A5: Apply \u03c0-type EMI filters to DDR4 DQ lines (22\u03a9 resistors + 100pF caps). Stagger memory chip placement to break resonant cavity effects.
