IP Product: DDR3 SDRAM Controller Supporting UniPHY

Why do I observe read errors with my UniPHY based memory controller IP after migrating the IP to a different version of the Quartus II software?

Description

You must run the pin_assignment.tcl script after migrating the UniPHY based memory controller IP to a different version of the Quartus® II software. Newer versions of the Quartus II software may introduce additional assignments. Without these assignments, the UniPHY based memory controller IP may not function correctly.
