Publisher Summary This chapter discusses the first of the five phases of FPGA development. The design package is information provided to a designer, and it can vary from design to design and company to company. With that in mind, this chapter presents some basic information that will help one understand the material, take some decisions prior to creating the design, and finally to develop a design from that information. The Design phase and the elements that lead to the Success or failure of the design have been explained. Emphasis is given on the design package containing all the relevant design information, like requirements specification and timing diagrams as failure to do so could lead to costly errors at a very late stage. Tips for evaluating the design package include analyzing, getting clarifications and storing documents for future retrieval have been given. Predesign decisions on selecting the design's format, the FPGA Manufacturer and Development Tools have been dealt with in detail. Pros and cons of Complete and Standalone tools and their comparison have also been made. Choosing between Automatic code generator and Manual code generator has been touched upon briefly. The chapter shows a VHDL design consisting of four main parts: an optional heading, library declaration, entity section, and architecture section.
