QuartusII Synthesis

Hello,

I am using quartusii to simulate my design in linux.I have instantiated <stratixiii_lcell_comb>,<dff> primitive in my design.

But when i try to compile it it gives the error <VHDL error : object "stratixiii_lcell_comb" is used but not declared>

I included the libraries ::

library altera;

use altera.altera_primitives_components.all;

library altera_mf;

use altera_mf.altera_mf_components.all;

I am using stratixiii as device family.Do i need to include stratixiii lib , if yes can anyone advice which one to include.

Thanks in advance.
