A method for identifying design rule checking (DRC) violation types within an integrated circuit (IC) chip design includes receiving an IC chip design layout, and performing a DRC process on the IC chip design layout to identify DRC violations. Further, the method includes generating clustered heatmaps from heatmaps generated from the DRC violations. The method further includes identifying a first DRC violation type and a corresponding first cell pair within the IC chip design layout by analyzing the clustered heatmaps with a diagnostic model.

Cell overlap violation diagnostics with machine learning

A computer implemented method for validating a design is presented. The method includes generating, using the computer, a graph non-decomposable to a colored graph representative of the design, when the computer is invoked to validate the design. The method further includes identifying, using the computer, at least one guidance to at least one conflict in a mask layout associated with the design, the conflict causing the graph to be non-decomposable.
