Why do I see an instantiated register called "xlpersistentdff" in my System Generator for DSP design?
Solution
The register is a persistent register which is placed in every design to make sure that there is at least one synchronous element present in every design. This register will be present in the top-level HDL file but is not part of the user design and can be safely ignored.
