Abstract

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.

receive design data for an integrated circuit (IC) design;
determine, based at least in part on the design data, power characteristic data for the IC design, wherein the power characteristic data identifies a power intent hierarchy for the IC design and violations present within the IC design;
generate within a graphical user interface (GUI), display components corresponding to individual components encompassed within the power intent hierarchy;
generate, within the GUI and based at least in part on the design data, one or more graphical links between displayed components;
generate, based at least in part on the power characteristic data for the IC design, one or more violation clusters each comprising a plurality of design violations for the IC design, wherein design violations within each of the one or more violation clusters are characterized as having at least one shared root cause;
associate the one or more violation clusters with the one or more graphical links;
overlay a plurality of interactive elements over the GUI, wherein the plurality of interactive elements comprise:
at least one interactive link element providing data indicative of the one or more violation clusters in association with corresponding ones of the one or more graphical links;
at least one root-cause element corresponding to the at least one shared root cause; and
a graphical association between the at least one interactive link element and the at least one root-cause element to indicate a relationship between the at least one root-cause element and the at least one interactive link element.

2. The system for generating a cluster-based power architecture interface of claim 1 , wherein the at least one interactive link element has associated detail data indicative of individual violations within a violation cluster, and wherein the processor is configured to:
upon receipt of input indicating interaction with a first interactive element, display a detail element within the GUI comprising at least a portion of the detail data.

3. The system for generating a cluster-based power architecture interface of claim 2 , wherein the detail data comprises a plurality of interactive links associated with individual violations within the violation cluster, and wherein the processor is additionally configured to:
upon receipt of input indicating interaction with an interactive link associated with a first individual violation, display a detail-view GUI providing a violation-specific schematic associated with the first individual violation.
