CDC Analysis at SOC level involves huge challenges in terms of capacity, quality of results, and ease of debug, dependencies and ownership of IPs. The flagship SOC designs are typically the biggest and the most complex. IPs are sourced from both internal as well as external design teams and they are integrated at the SOC level later in the design cycle. With the hierarchical approach, CDC analysis can be done in a bottom-up approach wherein CDC analysis for the IP level is done first and its abstract model (HDM model) is created based on SOC/Subsystem level parameters and configurations. An HDM model provides an abstract representation of the IP, but also with visibility of the internal logic. When consumed at the SOC level, HDM models improve ease of debug, performance and quality of results.
