Design Methods for Complex Digital Circuits

The paper classifies different types of digital IC products emerging from enhanced technology. The different production volumes to be expected for the different classes are analyzed with respect to key cost drivers. A new class of high complex application specific products with moderate production volume but increasing market share is identified. General strategies for managing and reducing complexity are analyzed with respect to their applicability to IC design. The ASC hierarchical design methodology based on abstraction and high level modeling is presented. The integrated ASC Chip Design System is outlined.
