Very good, found it in Quartus II ver. 4.1:

Ignore LCELL Buffers
("More Settings" is a button which opens the "More Analysis & Synthesis
Settings" form.)
Now for some more reading and testing...
Thanks!

In my Quartus II ver. 4.0

set this to On (Default is off) and recompile..
If i remember correctly you will get a warning message that it synthesised
them away..

Well, I'm learning more as I go... It seems that you have to
compile the design before you can use the Node Finder. So I
added an LCELL between the multiplier and the ram, and named
it mult_out. I can then add mult_out to my .vwf file and it
appears as it should in the output vectors, with the correct
waveforms.
Now if I can get the LCELL automagically stripped out when I
create the actual device...

I am trying to perform a functional simulation of a circuit
which contains a multiplier (LPM_MULT) feeding into a ram
cell (VHDL code). Using the Node Finder, I have added the
output of the multiplier "mult:inst|result" to my .vwf file,
but I get the following warning message when I simulate:
Warning: Can't find node mult:inst|result[0] for functional
simulation. Ignored vector source file node.
I have read the question posed by Christos (10/9/2003), and
responded to by Subroto Datta (10/9/2003).
Since I am performing a functional simulation, and the Node
Finder can find the node of interest:
(1) Should the LCELL still be necessary?
(2) Why can't the node be found, is it stripped out when I
run the "Generate Functional Simulation Netlist" tool?
