Comprehensive CDC Verification Using Advanced Hierarchical Data Models

In this paper, we describe the hierarchical data model (HDM), which is the backbone of the Questa CDC hierarchical verification solution. The HDM is equivalent to an abstract CDC model of the IP that captures the CDC intent of the block along with its integration rules. It is a generic data model that can be seamlessly reused across releases and across designs wherever the IP is reused. It can also be an performance efficient alternative to the traditional flat CDC verification flow.
