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

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Quartus® II software you may see this error message when the WEAK_PULL_UP_RESISTOR option is disabled in a project targeting Cyclone® IV devices.

Active Serial (AS) configuration pins have internal weak pull-up resistors that are always enabled, so setting the Weak-Pull-Up option to OFF should not result in this error message.

 

Resolution

To workaround this, remove the following line from the Quartus Settings File (.qsf):

set_global_assignment -name WEAK_PULL_UP_RESISTOR OFF

This problem is scheduled to be fixed in a future version of the Quartus II software.
