The independent claims of this patent signify a concise description of embodiments. An automatic process for determining and/or predicting the original root-cause(s) of a violation is proposed using two major enhancements on top of the current VC-Static solution. First, an information repository is created by mining various Static checker components' analysis information, and second, an analysis framework is created which systematically prunes the above-mentioned information repository to find the actual root cause(s) of the violation. This Abstract is not intended to limit the scope of the claims.

Automatic root cause analysis of complex static violations by static information repository exploration

Disclosed herein are system, method, and computer-readable storage device embodiments for implementing automated root-cause analysis for static verification. An embodiment includes a system with memory and processor(s) configured to receive a report comprising violations and debug fields, and accept a selection of a seed debug field from among the plurality of debug fields. Clone violations may be generated by calculating an overlay of a given violation of the violations and a seed debug field, yielding possible values for a subset of debug fields. A clone violation may be created for a combination of the at least two second debug fields, populating a projection matrix, which may be used to map violations and clone violations to corresponding numerical values in the projection matrix and determine a violation cluster based on the mapping having corresponding numerical values and score(s) satisfying a threshold, via ML. Clustering may further be used to generate visualizations.

Automated root-cause analysis, visualization, and debugging of static verification results

A system and method generates cluster-based power architecture interfaces for an integrated circuit (IC) design under test (DUT) debugging by receiving design data for an IC DUT, determining power characteristic data for the IC DUT, generating display components within a graphical user interface (GUI) corresponding to individual components encompassed within a power intent hierarchy corresponding with the IC DUT, generating graphical links between displayed components, overlaying interactive elements corresponding with generated violation clusters over graphical links, and providing root-cause interactive elements within the generated GUI having visual associations with the interactive components corresponding with particular violation clusters.
