Design Reuse- Introduction• Re-Use is very important, especially with fast time tomarket• If we can re-use a block then it can yield a very fastproduced design– As part of the design has already been implemented– Ideally, we drop the block into our top-level design• At the extreme, we have System on a Chip (SoC) designswhich are composed of blocks from multiple authorswhich are simply connected together to form largedevices (e.g. Set Top Boxes for Television)22
Design Reuse- Requirements• Block must be well specified and documented– The author may not be the end user so the full functionality ofthe block should be well documented (both inline within codeand external documentation)• Block generally has to be highly cohesive to be able to bere-used– For example, if we are designing a peripheral block for amicroprocessor (e.g. Dialing block) then it would be better if theblock could be design in two sections- one general blockconnected to a processor specific block• Other issues (e.g. testability etc.)23
