I was now searching for an error in my design for hours....
As a last try I removed the folder db in the quartus project
folder, compiled again and -- voila, the design worked!

Weird!

BTW: I'm invoking Quartus in batch mode from a Makefile.
Anyone had similar experiences?

Hi Martin,

This problem was reported by the Altera applications group on Monday
this week and we will have a fix ready. This global patch which is
undergoing testing will be made available by Friday noon and a link will
also be posted here. This problem is seen if you are compiling a design
which has encrypted IP. This affects Nios II designs and four of the
communications cores. In the meantime delete the db directory. This problem
only affects Quartus II 5.1. Earlier versions of Quartus are not afected.

We apologize for any inconvenience this may have caused.

Hi Subroto,

thanks for the reply. I've added a 'rm -r db' in my Makefile ;-)
However, my design does not used any encrypted IP, just plain
VHDL files.
