Error:129001 Input port OFFSET on atom "|dll_ctrl_a_wys", which is a statixv_dll_offset_ctrl primitive, is not legally connected and/or configured

Description

You may get the above error when you synthesize the ALTDLL Megafunction in Stratix® V with the Quartus® II software version 13.1 if you turn on Instantiate dll_offset_ctrl block and Set statically to options for DLL Phase Offset Control A or DLL Phase Offset Control B block.

Workaround/Fix

To work around this error, modify the value of the dll_ctr_a_wys.use_offset parameter from true to false in the <DLL variation name>.v file and then re-run synthesis.

This issue will be fixed in future version of the Quartus II software.
