Families Supported

The following table shows which families support this constraint and which file formats and tools you can use to enter or modify it:

Purpose

Use this constraint to set the location of a pin.

For ProASIC3/E and Axcelerator, you can use the set_io command in a PDC file to assign I/Os to pins as well as set the attributes of an I/O. For ProASIC PLUS and ProASIC, you can use the set_io command in a GCF file to assign package pins to I/O ports or to locate I/O ports at a specified side or location of a device. For earlier families, you can use a PIN file to set the location of a pin.

Tools /How to Enter

You can use one or more of the following commands or GUI tools to assign an I/O to a pin:

• PDC - set_io

• GCF - set_io

• PIN - PIN <pin_name>; PIN:<package_pin_number>

• PinEditor (MVN) - Assigning pins

• PinEditor (non-MVN) - Assigning pins

Note: You can also set the location of a pin using the pin_assign command in a Tcl script.
