Insider Tips

  • 1.SerDes and high-speed I/O are core — know equalization, CDR, eye diagram analysis, jitter.
  • 2.PCIe in depth — Gen4/Gen5 link training, TLP/DLLP/PLP layers, credit flow control.
  • 3.Ethernet knowledge expected — MAC/PHY interface, clause 74/91, FEC, link layer.
  • 4.Large-scale RTL design experience valued — know design partitioning, CDC strategies at scale.
  • 5.Network switching fundamentals — packet buffers, QoS, arbitration schemes, cut-through vs store-forward.
