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
