Principles of Digital Design CMPE 212 Class 14 - Designing With Digital Components Slide: 3 Modular Design Top-down modular design is the most popular methodology A function is initially specified at a high level of abstraction and then decomposed into lower-level modules Decomposition enables reuse of sub-functions and available modules (adder, comparators, etc.). After implementation, the modules are integrated from the bottom-up.
