Abstract: An electronic design automation (EDA) data processing system includes a version graph database and a controller. The version graph database stores a plurality of different versions of graph data sets. Each graph data set corresponds to a respective circuit component located at a given hierarchical level of a semiconductor chip design and each graph data set tagged with a version identifier (ID) indicating the version thereof. The controller determines a hierarchical circuit included in the semiconductor chip and determines a plurality of targeted circuit components that define the hierarchical circuit. The controller determines targeted graph data sets from the versions graph database that correspond to the targeted circuit components, and obtains the targeted graph data sets having matching version IDs such that the targeted graph data sets are the same version.
