In this paper we present the concepts and the organization of the FP7 Project SMAC (SMArt systems Co-design), an Integrated Project (IP) of the 7 th ICT Call under the Objective 3.2 "Smart components and Smart Systems integration". We describe in particular the project objectives and its organization, and how it addresses the challenges of the integration of heterogeneous and conflicting domains that emerge in the design of smart systems. The main outcome of the SMAC project is the development of flexible software platform ( the SMAC platform) for smart subsystems/components design include methodologies and EDA tools enabling multi-disciplinary and multi-scale modeling and design, simulation of multi-domain systems, subsystems and components at all levels of abstraction, system integration and exploration for optimization of functional and non-functional metrics.

Electronic systems are increasingly fusing multiple technology solutions exchanging information both at electrical and at nonelectrical levels, and in general both analog and digital operation coexists in multiple physical domains. this paper introduces a homogeneous multi-domain design methodology which blurs analog and digital boundaries and enables the design of etherogeneous electrical and non-electrical building blocks. the methodology is based on the identification of four fundamental quantities (quadrivium), namely signal-to-noise ratio, signal-to-interference ratio, impedance and consumed energy, applicable to both electrical and multiphysics components. Based on their constraining and their propagation on an ensemble of transactions in time domain, these four elements can be used across different domains (digital or analog), and permit architects to extract internal features, so that these are intrinsically oriented to successive physical and technology-related implementation and modeling.With example application cases, we show that these four quantities in turn define design constraints of electrical and nonelectrical internal units. after presenting an electronic design example, to show applicability in multiple physical domains, the paper discusses and applies the quadrivium also in the context of a mEms sensor and microfluidic components.
