Standardization Of HDMs For Hierarchical CDC And RDC Analysis


Currently hierarchical data models (HDM) must be generated with the same EDA tool that customers will use to consume the HDM for CDC and RDC analysis at the SoC level. To resolve this problem a CDC Working Group was created within the Accellera organization. The goal of this Working Group is to create a standard format for HDMs so the models can be consumed by any EDA tool irrespective of the s... » read more
