vht test bench examples

Thank you for the help

In Quartus I made a vht test bench file. When I compile quartus I tell it to run the test bench in modelsim. When modelsim loads it lists all the signals in the Objects window and loads the wave window. All my input signals are being shown as undefined, however it does show signals being propagated internally within my system (which is to be expected, not everything in my system is dependent on an input signal).
