Wireless system validation using VHDL-AMS behavioral antenna models: radio-frequency identification case study

In order to generate a first-time right design, system level modeling and simulation is a must. Thus, functional validation of integrated wireless systems requires the development of antenna models compatible with the microelectronic design tools. This paper presents the first VHDLAMS model of a wireless system that includes an RF link. Firstly, a behavioral model of a simple antenna is presented, then, a complete RFID system behavioral model is described at the system level. Finally, some examples of system simulation are presented in order to demonstrate the interest of our approach.
