Chapter 13 features the design hierarchy, in which a system is gradually divided into smaller parts. Mechanisms and language constructs of VHDL used to specify and configure a hierarchy are examined. | HIERARCHICAL DESIGN RTL Hardware Design by P. Chu Chapter 13 1 Outline 1. 2. 3. 4. 5. Introduction Components Generics Configuration Other supporting constructs RTL Hardware Design by P. Chu Chapter 13 2 1. Introduction • How to deal with 1M gates or more? • Hierarchical design – Divided-and-conquer strategy – Divide a system into smaller parts RTL Hardware Design by P. Chu Chapter 13 3 RTL Hardware Design by P. Chu Chapter 13 4 Benefits of hierarchical design • Complexity management – Focus on a manageable portion of the system, and analyze, design and verify each module in isolation. – Construct the system in stages by a designer or concurrently by a team of designers. – Help synthesis process RTL Hardware Design by P.
