Layout XL Using Groups Like Instances

Mtabriz

is there a way to create a group of objects and then create a duplicate of said group that acts as an instance of that group rather than a separate copy? I'm trying to do some symmetrical layout with self contained sections but don't want to create a lot of sub-cells. My main goal here is to create a copy of a group of objects that tracks every change made to the original group so for example if I were to go inside the original group and add a wire, the same wire would be automatically added to the copy group(s). 

Thanks in advance.

  • Groups, either figGroups or logical groups, are a set of elements that exist at the same level of the hierarchy and are bound together. If you want to duplicate the objects in the group, you will be copying the individual objects rather than just referencing the group.The resulting data is independent of the original data. The only way you would get the functionality you want is to create a cell and instantiate that in multiple places, which you do not want to do.

    The database does not have support for tracking the two groups, this is done through the design tools such as modGens. You could write a bunch of code to emulate this capability but it would be simpler to push everything into a cell and pop the pins to the current level of the hierarchy for connectivity at that level.
