Due to the immense complexity of modern circuits, and verification challenges such as the state explosion problem for sequential circuits, this restriction of readily-available verification solutions severely limited the applicability of the approach in wider contexts.\r\n\r\nThis thesis closes the gap between the PCH approach and current advances in formal hardware verification, provides methods and tools to express and certify a wide range of circuit properties, both functional and non-functional, and presents for the first time prototypes in which circuits that are implemented on actual reconfigurable hardware are verified with PCH methods. Using these results, designers can now apply PCH to establish trust in more complex circuits, by using more diverse properties which they can express using modern, efficient property specification techniques.","lang":"eng"},{"lang":"ger","text":"Die bisherige Forschung zu Proof-Carrying Hardware (PCH) hat dessen Machbarkeit und Nützlichkeit gezeigt und einen Ansatz zur Zertifizierung der funktionalen Äquivalenz zu einer Spezifikation geliefert, jedoch ohne PCH mit aktuellen Erkenntnissen, Methoden oder Werkzeugen formaler Hardwareverifikation zu verknüpfen.

To cope with complexity, verification techniques working on different abstraction levels are best practice. SystemC is a versatile C++ based design and verification language, offering various mechanisms and constructs required for embedded systems modeling. Using the add-on SystemC Verification Library (SCV) elemental constrained-random stimuli techniques may be used for verification. However, SCV has several drawbacks such as lack of functional coverage. In this paper we present a functional coverage library that implements parts of the IEEE 1800-2005 SystemVerilog standard and allows capturing functional coverage throughout the design and verification process with SystemC. Moreover, we will demonstrate the usability of the approach with a case study working on a CAN bus model written in SystemC."}],"status":"public","_id":"37057","department":[{"_id":"672"}],"user_id":"5786","keyword":["Libraries","Generators","Transfer functions","Monitoring","Computational modeling","Driver circuits","Adaptation model"],"language":[{"iso":"eng"}]},{"page":"91-94","citation":{"ama":"Uribe DO, Stroop R, Hemsel T, Wallaschek J.

But until today their only business use lies in the field of backlighting systems for LCDs. Due to key features as light-weight, flatness, high step-up at low volume and high efficiency piezoelectric transformers should be usable in a much broader range of applications. This contribution returns to mind their operating principle, shows how to model and to develop such devices as well as give some aspects for development trends that will lead to further applications."}]}]
