The configuration variable TF_UNIFY_CELL_CHILDREN is provided to unify elements using the same parts (or with a common unfier) when those elements are sub-components of a single cell. If the cell constituent elements use the same part definition, or a common unifier part, they unify as single elements when the variable is applied.

Set TF_UNIFY_CELL_CHILDREN=1 to unify elements within BXC, CEL and PAZ cell libraries.
