Description There is a known issue with SOPC Builder, where you will see the above error if you try to generate your system after modifying the name of your DDR/DDR2/DDR3 clocks rather than using the default name given by the tool. The only workaround currently available is not to change the clock names. This issue will be fixed in a future version of Quartus® II software.
