set_iobank bankname [-vcci vcci_voltage] [-vref vref_voltage]
bankname
Specifies the name of the bank. I/O banks are numbered 0 through N (bank0, bank1,...bankN). See the datasheet for your device to determine how many banks it has.
-vcci vcci_voltage
Sets the input/output supply voltage. You can enter one of the following values:
Vcci Voltage |

1.5V |
LVCMOS 1.5, HSTL (Class I and II) |
-vref vref_voltage
Sets the input reference voltage. You can enter one of the following values:
Vref Voltage |
Compatible Standards |
1.5V |
SSTL3 (Class I and II) |
1.25V |
SSTL2 (Class I and II) |
1.0V |
GTL+ 2.5, GTL+ 3.3 |
