Hey! 

 

I have a problem by establishing a .vcd:  

 

What I'm doing is first:  

vsim inverter_tb add wave * vcd file myvcdfile.vcd run 100ns  

and then quit the simulation, BUT my .vcd file just contains the header, something like this:  

 

$date

$end 

$version 

ModelSim Version 6.5e 

$end 

$timescale 

1ns 

$end 

 

Thanks for suggestions
