Representability of Design Objects by Ancestor-Controlled Hierarchical Specifications (Extended Abstract)
Summary: Introduces VDAG, an ancestor-controlled hierarchical model for CAD enabling alternate module expansions to reduce storage and control instance placement. Characterizes VDAG-generable design forests, proves generability NP-complete (even bounded height), gives decomposition and a polynomial test for a natural class but NP-hardness for minimum-size VDAG.
