I am getting "Internal Error: Sub-system: CDB, File: /quartus/db/cdb/cdb_lutmask.cpp, Line: 566" from Quartus II 12.1

I think it is related to having multiple plls that I am reconfiguring. If I turn off the feature for one of the plls then I don't get the error anymore.

Hi,

The above error can causes by multiple reasons. May be there is an PLL and LVDS transmitter combination is not working properly in Quartus 12.1. So requesting to try on the latest version of Quartus.

Regards,
