How to look into the inner signals in Modelsim-altera

Hi, all !

Here is the usage problem with modelsim-altera 6.5b.

I want to watch the inner signals.

If I added "all signal in the design" or something to the wave in Object pane or sim pane,all signals will be added to the wave but have nodata. So,are there another methods?

    Thanks! So how about the zero-width signal shown in the modelsim-altera?Whatever times do you enlarge it! Do these signals mean anything?

    Yes you have to resimulate. Modelsim doesn't keep the history of all the internal signals during a simulation.

    Thanks,but that's what I asked. I mean the simulator may have database that restore all signals in the design. So,I have to re-simulate it after adding new ones according to your meanings?Any suggestions?

    The problem isn't clear according to your post. You know, that you have to restart or continue the simulation to get acquired data for newly added signals?
