Abstract: A relational database may be integrated into an integrated circuit design and analysis environment as the persistent data store for data associated with the design. This design data may include two or more abstractions of the design, such as layout data models and timing data models, in some embodiments. Design data may be partitioned in the database and indexed according to various attributes. The use of a relational database may facilitate cross-probing of design data corresponding to different abstractions of the design. The relational database may be queried to produce design reports and to identify design errors or weaknesses. Reports may be graphical or tabular, and may be displayed, printed, stored, or posted for viewing. Proposed modifications to a design may be investigated by modifying data in the relational database, rather than in the actual design. Design reports may be re-generated and compared with corresponding reports for the un-modified design.
