The layout cell I am working on has a given P&R boundary. Over the cell area I inserted a set of uniformly distributed metal lines using the Mosaic feature. However, some metal lines go out of the boundary and I need to cut them.
See the following picture as an example of the problem I am facing:
As far as I know there are two solutions:
- Flatten the metal layer and manually cut the protruding lines
- Use the Layer Generation feature (explained here).
However, both methods require the Mosaic to be flatten (actually haven't tried the Layer Generation method yet so can't say for sure). Since the metal pattern may not be the definite one, I was wondering if there were a way to keep the Mosaic intact so that I could modify if required. I was thinking about a "clipping" layer that once placed over the P&R boundary automatically "cuts" everything in my cell's scope. Maybe this function is already present in the software but I don't know the name of it.
Kind regards,
Michele
