Why does the synchronous clear of the fast input register operate incorrectly in Arria® 10 devices?

Due to a problem in the Quartus® Prime Software, the active state of the synchronous clear of the fast input register is the other way round in Arria® 10 devices.  For example, even though you use a fast input register with an active low synchronous clear in your design, the active state of the synchronous clear is wrongly set to high. 

The affected software versions are as follows:

• Quartus® Prime Pro Edition Software 22.1 and earlier
• Quartus® Prime Standard Edition Software 23.1 and earlier

This problem has been fixed in the Quartus® Prime Pro Edition Softwere version 22.2 and later.
