- 1-bit adder example revisited: see Figures 4.19 & 4.20.
- Another use of abstraction. Once we are convinced that simple circuits can be built using gates, we can design
higher-level constructs (like CPUs and memories) using these circuits as building blocks, without thinking about gates anymore.
- A straightforward, guaranteed-to-work method for transforming boolean functions into circuit diagrams is important because
we can write a computer program to do this for us.
- Today, computer engineers use sophisticated computer aided design tools to help automate and optimize the design
and layout of circuits.
