Description
Due to a problem in the Quartus® Prime Pro Edition Software version 21.3, you may see the Signal Tap "Add Simulator Aware Node" dialog box produces an incorrect result when the selected hierarchy contains an empty partition or an IP reuse partition or an IP core interfacing device IOs.
Resolution
To work around this problem, use the nodefinder to select nodes in the hierarchy containing an empty partition, or an IP reuse partition, or an IP core interfacing device IOs.
This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edtion Software.
