I/O Banks Interface

The I/O Banks setting shows the device I/O banks and the I/O voltage each bank uses. Some I/O banks support multiple I/O standards, and you can specify which standard the bank uses. These settings determine the FPGA pinout requirements and timing values of the interface blocks. Some I/O banks can support multiple I/O standards as long as the I/O voltages of the different standards are compatible.

To set the I/O voltage for a bank:
  1. Click Device Setting > I/O Banks.
  2. In the Block Editor, select the I/O voltage for the bank. You also select an I/O standard for GPIO blocks. The voltage you select for the I/O bank must be compatible with the settings you choose for any GPIO in this bank.
  3. Save.

The I/O banks that contain the HVIO pins support a dynamic voltage option. You can choose between 1.8 V or one of the other voltages (2.5, 3.0, or 3.3 V). See Dynamic Voltage Support.

Note: The I/O banks and their legal configuration are device and package specific. Refer to the data sheet for your chosen FPGA for details on which I/O standards it supports.
