    Does your top-level schematic file have the same name as your project?

    If not, you need to set it explicitly in Assignments -> Settings -> General in Quartus II main menu.

    If there is problem with hierarchy, check your design to make sure every sub-module is instantiated correctly.

    have you output the top level schematic as an HDL file? Modelsim cannot simulate schematic files.
