ncvhdl8.2 - can I create symbols for my VHDL structures and use them in schematics

If you want to instantiate the VHDL blocks in a schematic, then yes, you'll need to create symbols - and you can do that using Create->Cellview from Cellview (say in the schematic editor). If you've compiled the code into your library using:

ncvhdl -use5x -work libName code.vhd

for example, you'll end up with an "entity" view under the cell, and that can be used as the source view for create cellView from cellView.

You can netlist (and simulate) from schematics using Launch->Simulation->VHDL Toolbox (in the schematic window), or Tools->VHDL Toolbox (from the CIW).

Note that IC612 is no longer supported - you should really move to IC613.

Hello Andrew,

Thanks a lot for your help. I am trying follow your instructions, but still not getting exactly there. Can you elaborate it a little bit ?

Let's say, I have a library 'trial' in which I created a cell "DFF" with cellviews, entity and behavioral. I wrote the code in those cellviews using vi editor. Then opened nclaunch, compiled the code successfully.

Now, I want to make a cell DFF_2 in another library trial1, which connects 2 DFFs. How do I go abt it?

Right now, I am creating a new cellview 'symbol' using FILE->NEW->CELLVIEW for DFF cell. Then in trial1, I create schematic cellview for cell DFF_2, using create instsnce I use DFF symbols, then connect them. When I go to create 'cellview from cellview' for this DFF_2. where I try to create VHDL cellview from schematic cellview. but I get only an entity cellview with inputs and outputs of DFF_2, no architecture.

When I try to use VHDL toolbox to simulate this schematic DFF_2, for "check working cellview and netlist" i get : no units analyzed and for "check hierarchy and netlist full hierarchy" i get : unable to find unit ..schematic.

I think as I created DFF symbol using FILE->NEW->cellview and not from create cellview from cellview, that symbol is not connected to DFF code. But I only have vi editor open for entity and behavioral view for DFF, how do I select option create cellview from cellview?

thanks in advance.
