Viewing internal signals with ModelSim

[Joseph]

Hi all,

I am simulating a entity with Modelsim via Xilinx Webpack. Modelsim
only displays the input/output signals of the simulated top entity.

Is there a way of viewing the internal signals declared in the
architecture of the entity without adding them to the port outputs of
the simulated top entity?

Thanks very much

Regards

Modelsim will optimise your design by default and hence you might loose some
internal signals, try "log -r *" before running your simulation.

Try the ISE simulator - it allows you to watch in internal signals by drag and drop.

If you then switch to the modelsim with a saved simulation, will the Modelsim give you the internal signals as well (strange )

Sorry if this is obvious, but you have tried descending the hierarchy in
the "Workspace" window? Signals at the current level are listed in
"Objects", & you can add them to the display.

I don't know if this will help you, but I've noticed that the new
version of Modelsim optimizes away internal signals by default. I have
to use a new argument in vsim:

vsim -voptargs="+acc" test
