Hi @Tim Edwards, another query : I try to create a label on the instantiated cell , but the issue is the tool does not take the label. It only takes if i create any layer above it and then out the text. In this case WL[0]. Is this expected ? Or there is a way to propagate the label to the layer below ?

The preferred way is to do what you did, which is to draw some of the layer you want the label attached to. But, you can also set the "sticky" property when you create the label, and specify the layer you want it to connect to.
