Hi All,
I am new to Quartus II, and am trying to run a functional
simulation. I am using the "Vector Waveform Editor" and put in input
nodes and some of the output nodes that I want to see. However, when
I run the functional simulation, I do not see the waveforms for some
of the input/output nodes. The warnings say: "Can't find node <X> for
functional simulation. Ignored vector source file node." The warning
for the inputs is: "Can't find signal in vector source file for input
pin <X>."
How do I fix this error? Thanks in advance.
I have tried the following:
This warning occurs when after synthesis, the node you intend to see is
buried inside a logic element or is optimized away completely.
The best thing to do is to go to the Assignment Organizer (Ctrl+Shift+A) and
do the following:
In the "To" field, add the name of the node that disappeared in the
simulation. In the "Assignment Name" field, choose the "Implement as output
of logic cell", and in the "Value" field, choose "On".
Do this for all the nodes that disappeared (buses and wildcards are OK when
entering the assignment) an you should be OK.
However, it doesnt seem to do the trick
