Sometimes you just want less – Splitting IC layouts saves time and resources

By Design With Calibre

One slice instead of the whole pizza. One single 1¼“ nail, not a bucket of 600. One white undershirt, not a package of five. Sometimes you want just a small part of something that is traditionally delivered as a larger whole. Getting the full package means you’re simply wasting money and/or resources. That’s the idea behind splitting an IC layout…

Don’t need the full-chip layout? Save the part(s) you do need as a smaller, separate layout. Not only does it load faster and use less memory than the full-chip layout, but it’s also much easier to view and share just those specific parts of the layout needed for a given task.

The best part is…how much or how little to include in a layout is up to you. Using the Calibre® DESIGNrev™ layout viewer, you can define which parts of a layout to keep or remove to get the desired layout. This approach allows you to create as much context as you want around your region of interest.
