veriloga and symbol do not match properly
May 23rd, 2008, 6:24am
 
Hello the designer community,
I am working with cadence.
I have a symbol using a bus bn<12:0>, when I create a veriloga view , a pop up with the veriloga text concerning the view is generated.
the bus is written as [12:0] bn.
When  I compile the veriloga view, cadence complains.
The simulations are working but in the ciw windows I get
ERROR: Terminal "bn<12:0>" is defined in veriloga text but not in symbol view.
The terminal in symbol view is either missing or ignored.
ERROR: Terminal bn<0:12> in symbol cell view is not defined in veriloga text.
The terminal in symbol view is either missing or ignored.


I don't understand, I tried generating the veriloga view from the symbol view, I tried to generate the symbol view
from the veriloga view... same problem.
The cdf definition seems ok ...
If I change the order on the veriloga view [0:12] bn the compilation is clear but the simulation is crashing.
"Netlister: Cannot find terminal 'bn<0:12>' on instance 'I4' in lib 'CDSPGA' cell 'testTOPVIEWPveri' view 'schematic'."
Does somebody had such a problem ?
      have a nice day
