Breaking components into encapsulated
structural units greatly simplified the design process. Once the alu
was designed, the rest of the datapath design needed only to be
concerned with providing the correct inputs on the input pins, rather
than being concerned with all of the internals of the alu. Also
hierarchical design can isolate errors and the changes required to
fix them. Otherwise, any change to any part of the design would
require the entire project to be recompiled.
