Error (169187): Following feature(s) of I/O pin has invalid setting(s) in the configuration scheme ACTIVE_SERIAL when the pin is placed at pin <location>

Description

You might see this error message in the Intel® Quartus® Prime Software if you change the current strength of the ASDO pin from the default value, in a project targeting Cyclone® III or Cyclone® IV devices.

The ASDO pin only supports the default value for current strength.

Resolution

To work around this, remove the following line from the Quartus Settings File (.qsf) for the ASDO pin:

set_instance_assignment -name CURRENT_STRENGTH_NEW <current strength value> -to <pin_name>
