2.5.5. I/O Standard Selection and I/O Bank Supply Compatibility Check

  • Select a suitable signaling type and I/O standard for each I/O pin. The I/O banks are located in rows along the top and bottom periphery of the device. Each I/O sub-bank contains its own PLL, DPA and SERDES circuitry.
  • Ensure that the selected I/O standard is supported in the targeted I/O bank.
  • Place I/O pins that share voltage levels in the same I/O bank.
  • Verify that all output signals in each I/O bank are intended to drive out at the bank's I/O voltage level.
  • Verify that all voltage referenced signals in each I/O bank are intended to use the bank's VREF voltage level.
