DDB: An Object Oriented Design Data Manager for VLSI CAD
Summary: DDB uses an object-oriented data model for VLSI/CAD data and a UNIX/C++ design data manager used by diverse CAD applications. Benchmarks show it outperforms commercial OO-DBMS, with easier data access and a modular architecture that boosts CAD software productivity. (summarized by gpt-5-nano on Feb 09 2026)
