I fixed it, but now I have different problem. the ddr2_example_design simulation doesn't work well. I implemented a Hard memory interface (ddr2) for ARRIA V in the megawizard. And I wanted to activate the example design. I run ddr2_example_design example design exactly as described in README.txt file - open the Quartus project "generate_sim_example_design.qpf" and select Tools -> Tcl Scripts... -> generate_sim_vhdl_example_design.tcl and click "Run".The generated files will be found in the subdirectory "vhdl". - To simulate the example design using Modelsim AE/SE: 1. Move into the directory ./verilog/mentor or ./vhdl/mentor 2. Start Modelsim and run the "run.do" script: in Modelsim, enter "do run.do". In the Wave I don't see any action in the ddr2 signals(dq,dqs) its always in tri-state. Attached the Wave screenshot.
