Abstract: A method is provided for using an integrated circuit design tool to optimize a circuit design for an integrated circuit. Optimizations that affect first circuits in the circuit design and that are performed during synthesis of the circuit design for the integrated circuit are recorded in first records in a database. Second records are recorded in the database that indicate second circuits in the circuit design that fanin to or fanout from the first circuits and that are affected by the optimizations. A root cause of at least one of the optimizations is determined using the first and the second records in the database. A sequence of the optimizations affecting the first and the second circuits is determined using the first and the second records in the database.

Abstract: Systems and methods for creating virtual stop-off points in a movie title, where the viewer can explore interesting content using zoom, pan and gamma controls are provided. Methods include creating an interest point from one or more digital video titles. Systems include a composer for creating interest points in a video and a viewer for manipulating and displaying the interest points.

Abstract: Systems and methods for creating a video montage from titles on a digital video are disclosed. Montages include one or more video segments from one or more video titles assembled together into a single video montage. Systems include authoring tools for assembling montages and display tools for displaying montages. Methods include identifying video segments for incorporation into the montage, marking the segments, and using the markings to view the montage.
