Partitioning Features
VHDL provides many high-level features to help you manage a complex design description. In fact, design management is one of VHDL’s key strengths when compared to alternative design entry languages and methods.
The modularity features (procedures and functions) that we have seen in previous chapters are one aspect of design management, allowing commonly-used declarations and sequential statements to be collected in one place. Design partitioning is another important aspect of design management. Design partitioning goes beyond simpler design modularity methods to provide comprehensive design management across multiple projects and allow alternative structural implementations to be tried out with minimal effort.
Design partitioning is particularly useful for those designs being developed in a team environment, as it promotes cooperative design efforts and well-defined system interfaces.
