Using VHDL-AMS to simulate aging behavior of electronic components

Gerhard Hofmann¹,

V. Georgiev

Abstract: Reliability of electronics is in the automotive industry very important. The average age of cars in Germany was 9 years at 2015. i Normally the life time is evaluated by the environmental test according ISO 16750. The content of this paper is to contribute that computer simulation of aging is a possible way to evaluate electronic circuits in the define phase. For this reason a VHDL-AMS simulation models is used to model aging behavior of a resistor.

In this paper a design method for mechatronic functions in an early design phase under consideration of the requirements of functional safety is proposed [14]. The goal of the method is to discover threats for the safety goals and to prove or optimize the diagnostic mechanisms. At the current design process a lifetime endurance test is performed in a late project phase. In order to avoid unexpected late design changes the method should be applied in an early design phase. The method is an additional way to avoid design failures for E/E functions with special focus on aging in the field of functional safety applications. The method is developed out of three standards VDI 2221 methodology for development and construction of technical systems and products [1]), VDI 2206 design methodology for mechatronic systems [2] and the ISO 26262 road vehicles -Functional Safety [3] by using the V-Model. Furthermore, a core element of the design method is simulating aging effects by applying VHDL -AMS. To demonstrate the design methodology a sensor out of the EGAS function is chosen as a safety relevant automotive system. The limitation is the availability of aging data for electrical components.
