The technical approach

Verdi will link simulation-based, “pre-tape-out” system analysis and verification with system validation and analysis of the physical prototype using measurement equipment, by:

  • Defining an unified system-level verification and validation methodology
  • Specifying a reuse strategy for verification IP between and within companies and for different product generations
  • Defining a path from verification IP to validation IP, to bridge the gap between verification and prototype validation

The unified system-level verification library developed in Verdi will provide new concepts to validate the SoS continuously throughout the product creation process. It will be based on methods to create and reuse verification components and IP such as stimuli, test-benches, analysis algorithms, etc. The Verdi methodology and library will be demonstrated with safety critical automotive SoS applications: power-train, in-vehicle networking, and airbag. As the methodology and library will extend industry-recognized standards (Universal Verification Methodology, SystemC and IP-XACT) they will be brought to standardization actively (Accellera, OSCI). This enables promotion and wider adoption among the industry of other heterogeneous applications.

Demonstration and Use

All concepts, libraries and methods developed within the Verdi project will be continuously evaluated using four representative automotive application scenarios – a braking system electronic control unit (ECU), an airbag chipset, a powertrain ECU and an in-vehicle network chipset. Verdi selected these automotive applications due to the different challenges and requirements like complexity, safety and heterogeneity.

Even though the project partners selected automotive applications for demonstration, the methods, libraries and standards can be applied to other application domains like automation technology and bio-medical.

Scientific, Economic and societal Impact

Electronic components will play a central role for the design of heterogeneous SoS. Thus, 90% of the innovations in the automotive industry will be realized by those embedded electronic components. For the design of those the verification becomes more and more the dominating time and cost factor within the design process. Thus, an efficient verification methodology will enable the cost effective realization of new innovative features without decreasing the safety and robustness of the overall system.

The partners expect that the Verdi methods will shorten the time to market cycle up to 25% and reduce the design costs by at least 20%. Additionally, Verdi will contribute to increase the safety and robustness and to meet the needs of upcoming standards like ISO26262. Hence, Verdi will have a share in maintaining Europe’s competiveness in the field of designing electronic components for heterogeneous SoS.
