“…To cover these cases, one might re-think the verification strategy and focus more showing application fitness, robustness, or even resilience (e.g. [49], [50]). This can be done best by an 'in-the-loop' simulation as shown in Figure 1.…”

In today's systems, analog and mixed-signal (AMS) circuits are tightly interwoven with HW/SW systems and the application. Hence, a verification of the AMS part alone is not sufficient any more, in particular considering its application in Cyber-Physical Systems. In order to guarantee 'first time right', the accuracy of the models, the validation of the application fitness, and in changing, uncertain environments will become at least as important. In this paper we discuss and give an overview of methods that strive for validation of AMS systems with increased coverage. We in particular focus modeling, verification and validation of uncertainties in the context of Cyber-Physical Systems.

“…Consequently, these methods must use parts of the system specification or design experiences in order to define and simulate errors efficiently at an early stage of development. As such, a novel approach to specify requirements and scenarios, known as Mission Profiles [31,32], has been developed in the automotive sector.…”

Intelligent automotive electronics significantly improved driving safety in the last decades. With the increasing complexity of automotive systems, dependability of the electronic components themselves and of their interaction must be assured to avoid any risk to driving safety due to unexpected failures caused by internal or external faults.Additionally, Virtual Prototypes (VPs) have been accepted in many areas of system development processes in the automotive industry as platforms for SW development, verification, and design space exploration. We believe that VPs will significantly contribute to the analysis of safety conditions for automotive electronics. This paper shows the advantages of such a methodology based on today's industrial needs, presents the current state of the art in this field, and outlines upcoming research challenges that need to be addressed to make this vision a reality.

“…2). This includes the worst-case distance (WCD) and spread of performance parameters with regard to the specification (functional and parametric robustness) [8]. In addition, it also includes the socalled "Robustness Indication Figure " (RIF) values of the most critical failure mechanisms in the module or component [5]- [7].…”

“…Validation hereby defines a set of tests and analyses to demonstrate that the module or component is suited for its intended use according to the given mission profile. In order to account for parametric and functional robustness of a module or component, its WCD parameters are calculated according to [8]. The RIF values of the module/component are calculated according to [5]- [7].…”

“…For components, this includes the identification of dominant failure mechanisms, such as corrosion, electromigration (EM), hot carrier injection (HCI), negative/positive bias temperature instability (NBTI, PBTI), stress voiding (SV), time-dependent dielectric breakdown (TDDB) and others. In addition, functional and parametric robustness require the worst-case distance (WCD) and spread of performance parameters to be considered with respect to the specification [8].…”

Consistent consideration of mission profiles throughout a supply chain is essential for the development of robust electronic components. Consideration of mission profiles is still mainly a manual task today despite rapidly decreasing robustness margins in modern automotive semiconductor technologies. Mission profile awareness aids the automation of robustness aware design by formalizing and partially automating the generation, transformation, propagation and usage of all component-specific functional loads and environmental conditions for design implementation and validation. In addition, it aids the development of electronic components in yet immature technologies or in technologies with tight parameter variation bounds. This paper introduces the general concept, requirements and context of mission profile aware design. The general design approach is presented along with key differences and enhancements to existing design approaches. A case study focusing on mission profile usage and electromigration failure avoidance is presented to demonstrate various aspects of mission profile aware design.
