Hi,

I have a very similar problem but I don't know how to find the solution. I compile,synthesize in Precision and I do the place and route in QuartusII. I want to simulate the whole project with the .vho and .sdo files in modelsim. I have written a testbench and when I tried to do the simulation I have the next errors: 

# ** Error: (vsim-SDF-3250) C:/Documents and Settings/Jose/Escritorio/Prueba_VHDL/Prueba_temp_5/simulation/modelsim/PROBA_vhd.sdo(35): Failed to find INSTANCE '/testbench/iCLK_50_ibuf/asynch_inst'.

¿If anybody can suggest any possible solution?

Many thanks
