Hierarchical Design
EE240B - Introduction
B. E. Boser 11
Good Hierarchical Design Strategies
• Start from high level abstraction– Add details later
• Establish early that specifications are met– When architectural changes are still feasible– Rework is minimal
• Are predictive– No drastic performance degradation during design process– Hmm …
