Virtuosity: Is the Coloring Data Compliant with the MPT Flow?

There is no second thought about the fact that compliant designs increase business efficiency and productivity. Designs that are not compliant increase the development life cycle of any product. In advanced node designs, to help you create designs that are compliant with the Multi-Patterning Technology (MPT) flow set up, we have introduced the methodology compliance checker on the Multi-Patterning toolbar. 

You must have faced a situation when the shapes in your design have coloring information but as per the MPT flow setup, these shapes should not be colorable. The methodology compliance checker can flag this. It can also flag any instances that are color shifted when as per the MPT flow they should not shift. Another flag that it can report is instance shapes having hierarchical color locks (HCL) in cases when the MPT flow is set up to not create HCLs. So, you can use the methodology compliance checker to help avoid rework at a later stage in the design by flagging discrepancies earlier during the design phase.

The MPT Compliance Checker Report displays such discrepancies in a format that details the errors at the current hierarchy level and inside the hierarchy. 

In addition to the above report, a marker is created for each current level error and you can browse this marker in the Annotation Browser. 

This feature brings in efficiency to your design process flow by ensuring that your design data is aligned to the selected MPT flow.
