VCD file doesn't show anything in GtkWave

[Database Administrator]

Hi:

I have used Icarus Verilog 0.8.4 on Suse Linux 9.1 to create a .vcd file
from a testbench. The .vcd file is shown below.

I also installed GtkWave 3.0.29 and used the command:

> gtkwave dual-fps.vcd

to attempt to display the waveforms from my .vcd file.

GtkWave opens with a nice window and a time axis, but no waveforms. It
has a text box which states:

VCD loaded successfully.
[12] facilities found.
Regions formed on demand.

And another graphic box which is labeled "signals" which shows "time"
but not any of the other signals.

Is there something wrong with my .vcd file, or Gtkwave?

Perhaps if someone can make the .vcd file display in their viewer, or
alternately send me a .vcd file they know works in GtkWave, I can figure
out which end the problem is on.

Thanks.

Did you try to:

click on the + in the SST window
click on DFM1
select all the signal names which appered in the Signals window
click Insert

Looks fine in gtkwave on my machine.

What is the SST window? Do you mean the zoom-in?

There is no reference to DFM1 in the GtkWave window.

Interesting. Windows or Linux? Perhaps I will test a Windows version...

Let's get some layout decided. At the top left there is a window which
says "VCD loaded succesfully[12] facilities..." right? You're also
seeing a window which has a title "Signals" and the content "Time" at
this point from what you're describing. Now below "VCD loaded ..."
window and to the left of "Signals" window, you should see a window
which has SST in its title with a '+' to the left of SST string. If
you see this click on the '+' and you should see your hierarchy. If
you don't see the SST window, it's possible that your GTK+ setup is
broken and you don't the right GTK+ installed.

Another option might be Dinotrace...

Hi, and thanks for the reply!

1. I have the '"VCD loaded succesfully[12] facilities..."'
2. I have the '"Signals" and the content "Time"'

But,

>you should see a window
>which has SST in its title with a '+' to the left of SST string.

I don't see this!

I think the conclusion is that my GTK+ might be screwed. This Suse
Linux has been known to have a shoddy GNOME installation at times. So
perhaps the libs are just old, or Suse tinkered with them and broke it.

Thanks for the help.

It isn't worth any more time at this point. I may try Windows, or may
just live with the text output from the Icarus simulator (which is usable).

I'll try GtkWave again once I have a chance to update Linux.

Wow, that looks ancient! Haven't used any raw X apps in a while.

I'll give it a shot...

My version of GtkWave (3.81) doesn't show the Signal Search Tree (SST)
window by default either. You can bring it up by selecting Signal
Search Tree from the Search menu. Or you can use the shortcut Shift-
Alt-T.

When using GtkWave, I can't show up vhdl signals created from
enumerated types such as state vectors. I'm think older versions of
GtkWave did show enumerated types, but I'm not sure. Anyone else had
this problem?

Jeez. That's about the one button in the whole program I hadn't pushed.

Now I can see waves. Thanks!
