Compile that testbench and then run it. –vermaete Feb 6 '15 at 7:43 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote First edit the if statement to get the correct results : if(enable <= '1') must be if(enable = '1') I simulated your code and no errors found. Simulation results was correct. Just open modelsim software, click file and change directory (for example to the address of test.vhd file) Then compile test.vhd and simulate it. Sometimes you should close modelsim and do the same stages again, because the library directory may be changed wrongly by yourself. share|improve this answer edited Feb 11 '15 at 7:50 answered Feb 6 '15 at 18:32 Am

I am trying to use a small testbench I wrote using the Quartus testbench template writer, but I am getting this error: Code: ** Error: (vsim-3170) Could not find 'C:/Users/nettek/QuartusProjects/Final Project - 11.3.16 - par/test/simulation/modelsim/rtl_work.tb_test1'. # # Error loading design # Error: Error loading design # Pausing macro execution # MACRO ./Test_run_msim_rtl_vhdl.do PAUSED at line 14 Steps I took: 1. Created a BDF file with two components in it, obviously it has input/output ports and some internal signals. 2. Created an HDL file from the BDF file. Added it to project. Removed the BDF file from project (did not delete it). 3. Created a testbench using the Quartus template writer. 4. Added the VHT file to project. 5. Took to Assignments -> Settings -> EDA tool settings -> Simulation -> Chose compile test bench and chose the VHT file. 6. Tools -> Run simulation tool -> RTL simulation which opened Modelsim. Of course I a
make a simple project, using schematic (one and gate) an dthen make a test bench waveform. I then do Simulate Behaviural Model but no matter what I do I always get # Error loading design with no other indication of erors. In the previous version of ISE and ModelSim it all worked so I am not sure what is error? Any help greatly appretiared!
