counter.v and tcounter.v simulation in ModelSim

Hi,

I'm new to testbenches so I set a goal to get those Verilog examples to work under ModelSim.

I'm trying to do the simplest of things - to run the counter.v and tcounter.v simulation and create a waveform. However once compiled, I have no objects hence nothing that can be added to the waveform.

I get no errors at all, just no objects after I compile. I see the two files under my library, I can click on the testbench file and it opens in SIM but objects window is simply empty. Attempting to add to waveform casues error - no objects found?

The funny thing is that if I compile the exact same design and testbench but use the vhdl version examples, then I do have objects available to add to a waveform and all works as expected.

What gives? Are the Verilog examples counter.v and tcounter.v screwed? They came from the original distribution and most of all - I get to compile them with no errors?

Thanks
