Need help viewing signals of the dut in the waveform

[Friend A]

Hi,

Here is the link to the playground:

https://www.edaplayground.com/x/4TRv

1. tb_fsm is the testbench that instantiates the DUT (fsm)

2. Currently I have these lines in the test bench:

$dumpfile("dump.vcd")

 $dumpvars(1)

3. After the simulation run the wavefile is displayed - The problem is I only have access to tb_fsm signals and not to the signals that are internal to the DUT.

4. How do I view the signals internal to the DUT ? for eg: tb_fsm.dutfsm.State or tb_fsm.dutfsm.Next

Note: When I use the GetSignals on EpWave I only see the testbench module and not the instantiated DUT. So I am not sure how to add the DUT signals to the waveform.

Thank you.

The reason is, you have specified dumpvars(1).
It just dumps top level variables and nothing from sub modules.
Please change it to dumpvars():
Yes, no arguments.
Try it.

Thank you - This solves the problem. I can now see signals from the DUT.
