Why is there a  ~bp appended to the end of the RZQ name when used with a RZQ_GROUP assignment?

Description

When instantiating an RZQ_GROUP assignment to the input RZQ pin name, the Intel® Quartus® Prime Software changes the input RZQ pin name by appending a ~bp.

Resolution

To work around this problem, change the assignment

from

set_location_assignment -name <input pin name>  -to <pin#>

to

set_location_assignment -name <input pin name>~bp to <pin#>
