Into Context• Center around procedures used for digital devices– Many principles applicable to all areas of electronic design.– Concentrate initially on all digital systems.• Designing chips to perform some specific task– From a simple application (e.g. ‘Glue-Logic’)– To a complex device (e.g. DVD, CD, Digital TV)– What needs to be optimised ?• Such ‘chips’ are now used everywhere and allow us tobuild electronic devices that would have been unheard ofeven 5 years ago !6
Some Definitions• Design– The process of taking a functional specification and producing asolution for this specification– There may be many different solutions, but we are only everinterested in producing a single one ! (although an optimisationcriterion may be extensibility).• Implementation– Implementing the design in some form– Or, in simple terms ‘building it’7
