scope:

This document defines requirements on VHDL models and testbenches. It concerns simulation and documentation aspects of VHDL models; specific aspects for logic synthesis from VHDL have not been included. Nevertheless, the requirements of this document are compatible with the use of logic synthesis. The document is focused on digital models; specific requirements for analog modelling have not been covered. The requirements are not applicable for the case when a design database is transferred in VHDL format as a netlist. The requirements are targeted to the finalised models rather than the models during the development. The purpose of these requirements is to ensure a high quality of the developed VHDL models, so they can be efficiently used and maintained with a low effort throughout the full life-cycle of the modelled hardware.
