A component database for behavioral synthesis of digital circuits should generate components that fit specific design requirements and provide information about a component's electrical and layout characteristics for possible architectural tradeoffs. A component server, called the intelligent component database (ICDB), is described. ICDB can dynamically generate components for a given set of constraints and attributes. Further, it provides delay, area, and shape estimates that support design tradeoffs on the microarchitecture-level. The ICDB is designed to be used with tools for behavioral, logic, and layout synthesis. Experiments demonstrate that such a component server can replace component catalogs with hundreds of pages.
