| What 
do you mean by not working properly? What errors do you get. I simulate with 
those files every day and it works perfectly. I would say that 
by not working you mean that there are no waves to see on the screen. I know 
that. Open a wave wave 
window by yourself and then run the simulation after it's finished add signals 
to the wave window. Do 
this sequence to do that: First 
run the simulation and then type this (or add to the top_modelsim.do 
file) view 
wave add 
wave -r /* restart -f run
