Equivalent to the DRIVE constraint in the Xilinx* Vivado* software, the CURRENT_STRENGTH_NEW logic option sets the drive strength of a pin. You must assign this option to an output or bidirectional pin; otherwise, the Compiler ignores it.

The following example shows how to set the equivalent DRIVE constraint with 12 mA to the output “q1”.

Example of XDC command:

# Set drive strength 12 mA to q1
set_property DRIVE 12 [get_ports q1];

Equivalent QSF command:

# Set drive strength 12 mA to q1
set_instance_assignment -name CURRENT_STRENGTH_NEW 12MA -to q1

For more information about the current strength feature in the device, refer to the specific device handbook and the Intel® Quartus® Prime Help.
