“…The concept of system scenarios were introduced in the late 1990s in the context of designing cost reduced systems by exploiting run-time workload information. An extensive overview of the stateof-the-art in this domain is available in [16]. In general, the system scenarios may be defined in an N-dimensional objective space where different metrics, assigned to separate objective axes are established, like energy, maximal power, footprint, throughput latency and so on.…”

Design margins are necessary to ensure reliable operation of integrated circuits over extreme ranges of environmental variations (Voltage, Temperature) and manufacturing Process variations. On top of these PVT variations, aging related parametric drift (e.g. due to BTI, HCI) also limits performance by requiring additional timing margin. In principle, corner based design methodology can be adopted. However, this approach is sub-optimal, because it applies margins which may be either too optimistic or pessimistic since it tends to ignore the correlation effects which exist inherently due to the circuit topology and the workload effects. In this paper, we propose a workload-dependent reliability aware optimization flow under the influence of NBTI aging by utilizing an optimal margining scheme. The proposed flow takes into account the relevant correlations in a design by modelling the degradation accurately and thus enables achieving the desired Power-Performance-Area (PPA) goals without severe reliability penalty.
