Modelsim SDF ERROR

HI, I am using the Modelsim 6.5b for the timing analysis, but when I add the SDO file to the similation, an error occurs showing as follow:Loading instances from E:/FPGA/sin/simulation/modelsim/sin_v.sdo# ** Fatal: SDF files require Altera primitive library.

I am using Verilog HDL, and this error never occurs to my teammate who is using VHDL.

THANKS FOR HELP!!!

    it says that it requires altera's primitive library. try adding the library into the vsim when doing simulation:

    vsim -L altera_ver work.<your top level test bench>
