Analysis of user requirements

VHSIC hardware description language (VHDL) 1076 is an IEEE standard which is undergoing a restandardization process. The restandardization process has gone through several phases. The first was the collection and analysis of users' requirements. It is shown how the decision process works, both at an administrative and a technical level. The origins of the requirements and the classification of the analyzed requirements are shown. The question of analog requirements is explained. A paradigmatic controversial example is detailed (global variables), and a list of available documents is given.<<ETX>>
