摘要: A system automatically routes interconnect of an integrated circuit design using variable width interconnect lines. For example, a first automatically routed interconnect may have a different width from a second automatically routed interconnect. The system will vary the width of the interconnect lines based on certain factors or criteria. These factors include current or power handling, reliability, electromigration, voltage drops, self-heating, optical proximity effects, or other factors, or combinations of these factors. The system may use a gridded or a gridless (or shape-based) approach.

摘要: A technique generates small scale clock trees using a spine-based architecture (using spine routing) while also using clustered placement. Techniques are used to control clock sink cluster contents in order to minimize clock skew, minimize clock buffer count, and minimize use of routing resources. This approach also provides the user with ample structure and control to customize small efficient clock trees, and can also reduce clock power consumption.
