For the design of Information and Communications Technology (ICT) related products, basic level of technical expertise and simple development tools were enough in the early 1980s. As time goes by, new generation products designed by engineers are always expected to be smaller, lighter and faster, due to the increasing global competition and the application of hardware and software in every area of our lives. In order to be able to respond to these needs, engineers have always had to produce new

... technologies and solutions. In this sense, hardware related technologies have been growing much faster such as System on Chips (SoC), displays, batteries and other materials used in the ICT products. Designers have been diversifying software development processes and tools remarkably for new applications and constantly developing new communication standards. In this article, all the main design phases are presented starting from the system design to the product validation and test. As can be seen from the relevant sections, in order to design an ICT product, very deep technical expertise, expensive development and verification infrastructures are needed in the relevant fields.
