Why do I see "Error(18108): Can't place multiple pins assigned to pin location" in my design with Partial Reconfiguration? - Why do I see "Error(18108): Can't place multiple pins assigned to pin location" in my design with Partial Reconfiguration? Description In projects with Partial Reconfiguration (PR) enabled, you might encounter the error message " Error(18108): Can't place multiple pins assigned to pin location " when you use the device AVST pins as dual-purpose mode. Resolution When you use PR External Host , the AVST pins are reserved for configuration and reconfiguration purposes; they are not available for dual purposes. Re-assign your pin locations to avoid this error. The AVST pins as dual-purpose are accessible when you use PR Internal Host . To avoid this error, include the following assignment in your Quartus® Settings File (.qsf): set_global_assignment -name FORCE_AVST_DUAL_MODE_PINS_FOR_PR ON The assignment is available starting in the Quartus® Prime Pro Edition Software version 24.1.
