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

Hi,

Very clear answer.

Hope it helps,

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.
