My file uses megawizard cores such as RAM, FIFO etc. After the synthesis in quartus2 , I got the following error in the modelsim when I simulated.

# ** error: (vsim-sdf-3250) top_module_name.sdo(0): failed to find instance '/instance_name'.# error loading design# error: error loading design # pausing macro execution # macro ./top_module_name_run_msim_gate_vhdl.do paused at line 12
