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 RS,

Thanks for your reply. I am targeting a stratix 3 device so I believe I am stuck with an older version. One of the PLLs is indeed used for 3 ALTLVDS_TX blocks. Does that put some restrictions on which plls or the number of plls that can be used with the ALTPLL_RECONFIG function?

Thanks
