copy/paste of wiring from refernce design

o In the reference design select File > Export > Subdrawing.
o Enable the elements you would like to copy in the Find Filter e.g. clines and vias.
o Using your left mouse button select, using window or by selecting elements, the items you want to copy.
o Select a point, such as a pin or XY location (You can type it at the Allegro command line) to use as a reference or origin for the elements in the reference design. Allegro's command line will state "Pick clipboard origin point"
o Save the drawing (.clp) file.
o In the current design select File > Import > Subdrawing.
o Browse to the saved drawing and select it. It will be attached to the cursor.
o Place the clip file at the correct location.

When you do this action, is connectivity still established? I ask because I have done this; however, when I update the netlist (import), it looks like the components in the subdrawing are not being included in the connected nets statistics and the placed components statistics.

What about reference designations as well? Do they need to be the same in the new source schematic?

I appreciate the help very much! I am adding a reference design to an existing board and this very topic is absoutely current with my existing task.

Thanks very much!

When you are in the export command you have the options of preserving:
Refdes
Nets of shapes
Vias
Testpoints on vias

That being said the connectivity, including the refdes has to be in the logic imported. The connectivity, provided the logic is in the design, should establish.

I would import the logic prior to importing the subdrawing.

Just so I am clear...I think this is the order I should follow:
1. Import the Reference Design Logic (schematic net list) into the board file.
2. Import the subdrawing into the board file.
3. As long as REF DES; connectivity is the same, then the connectivity should be established?

I plan on copy/pasting the schematic from the reference design into my new schematic, so preserving REFDES, etc. will be no issue.

I will try this and let you know if there are any issue. Thanks VERY much for the tip. That will save a lot of time/effort.

If the refdes and the connectivity is the same in both designs then yes, your list of the order would be what I would do. Good luck.
