A way to capture total area of a layout cellView

rtpdesigner over 8 years ago

leHiAreaDensity gives me the information I need in "TotalArea" - but it requires manual interaction.

leComputeAreaDensity would be perfect if it reported TotalArea, but it only analyzes the specified layer.

If anyone has something to share, please post.

Thanks

Hi Ananth,
Can you list your specification in a bit more detail. If you need the area of the cell view you can simply use the geGetEditCellView()~>bBox and then compute the area.
if you want the area of a combination of layers you can try using Diva rule to compute the area ( I need to dig into how its done.).

Thanks,
Naveen

Sure, cv~>bBox is useful, but it gets thrown off by invisible objects (steiners, etc).

This one seems to offer a workaround, but I haven't had time to investigate it :

Essentially, we are interested in the effective silicon area of the cell

Ya, I had a script to just delete all the invisible steiner stuff. Its always better to have a prBoundary or any other layer as your boundary and respect that.
