Accessing certain layer and get its ll and ur coordinates

Inas Mohammed

Hello,

I have a pattern of transistor has DRC errors for some spacings between successive rows. These errors will be solved if i add rectangles for these layer. so instead of adding the same layer several times in the middle, i thought to add it only once with dimension of this layer in the whole pattern, like the NW layer specially they all share the same NW.

So what i thought about is:

1) Grouping the instances.

2) Accessing the needed layer.

3) Get its ll and ur coordinates.

4)Create rect with this layer and list of gotten points.

5)ungroup them again.

So i need a skill script does this sort of function.

Thanks

Regards,

  • Actually the ~>lpp attribute on a cellView will list all the layer purpose pairs used in the hierarchy (provided the lower level cellViews are loaded in memory). However, the ~>lpp~>shapes will only give the shapes in the current cellView, as Ramakrishnan said. So you may find some lpp objects have no shapes, because the layer purpose is used in a lower level cellView, but there's nothing in the top level.
