set_iobank (Fusion and ProASIC3E)

Sets the input/output supply voltage (vcci) and the input reference voltage (vref) for the specified I/O bank. This command applies only to Fusion and ProASIC3E families.

 

set_iobank bankname [-vcci vcci_voltage] [-vref vref_voltage]

Arguments

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

Compatible Standards

3.3V

LVTTL, LVCMOS 3.3, PCI 3.3, PCI-X 3.3, SSTL3 (Class I and II), GTL+ 3.3, GTL 3.3, LVPECL

2.5V

LVCMOS 2.5, LVCMOS 2.5/5.0, SSTL2 (Class I and II), GTL+2.5, GTL 2.5, LVDS

1.8V

LVCMOS 1.8

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

0.8V

GTL 2.5, GTL 3.3

0.75V

Supported Families

Fusion and ProASIC3E

 

Note: Refer to the ProASIC3E datasheet on the Actel web site for details about the legal values for the vcci and vref arguments

Exceptions

Examples

The following example assigns 3.3V to the input/output supply voltage (vcci) and 1.5V to the input reference voltage (vref) for I/O bank 0.

 

set_iobank bank0 -vcci 3.3 -vref 1.5
