Local nodes are not visible anymore after simulation (Altera Quartus II )

Hello,

I made a simulation by the means of a vwf-file.

If I want to see the simulation results of signals which are neither inputs nor output what do I have to do?

Is there a difference between registered signals and combinatorical signals?

Thanks a lot.

Best regards

Hi,

Subroto Datta has already answered this to me, not so long ago. (Date:

Hope it helps, Christos

Hi,

I made the following declaration in my toplevel-file:

attribute preserve_signal : boolean; attribute preserve_signal of l_data_to_send : signal is true; attribute opt : string; attribute opt of l_data_to_send : signal is "keep"; This is the VHDL declaration to preserve nodes when performing the synthesis. But when starting the simulation I get the error message: "Ignored node in vector source file. Can't find corresponding node name l_data_to_send in design.

What does go wrong?

Thanks a lot.

Best regards Andres Vazquez
