The ModelSim cannot simulate the design contain lpm_dff

I had made a design include lpm_dff(lpm_dff.tdf) and try to use ModelSim-Altera 10.1b to simulate it. In Modelsim project not only the testbench file and the design file were added, the altera_mf.v and 220model.v , altera_primitives were also added. But it failed to simulate it with the error: Instantiation of 'lpm_dff' failed. The design unit was not found.

Is there any way to use ModelSim to simulate the design with lpm_dff?
