Complex applications with high demands on safety and reliability, such as autonomous driving, are simultaneously driving the requirements for test and diagnosis of VLSI circuits. Throughout the life cycle of a microchip, uncertainties occur that affect its timing behavior. For example, weak circuit structures, aging effects, or process variations can lead to a change in the timing behavior of the circuit. While these uncertainties do not necessarily lead to a change of the functional behavior, they can lead to a reliability problem.\r\nWith modular and hybrid compaction two test instruments are presented in this work that can be used for X-tolerant test response compaction in the built-in Faster-than-At-Speed Test (FAST) which is used to detect uncertainties in VLSI circuits. One challenge for test response compaction during FAST is the high and varying X-rate at the outputs of the circuit under test. By dividing the circuit outputs into test groups and separately compacting these test groups using stochastic compactors, the modular compaction is able to handle these high and varying X-rates.\r\nTo deal with uncertainties on logic interconnects, a method for distinguishing crosstalk and process variation is presented. In current semiconductor technologies, the number of parasitic coupling capacitances between logic interconnects is growing. These coupling capacitances can lead to crosstalk, which causes increased current flow in the logic interconnects, which in turn can lead to increased electromigration. In the presented method, delay maps describing the timing behavior of the circuit outputs at different operating points are used to train artificial neural networks which classify the tested circuits into fault-free and faulty." - lang: ger text: "Immer größere Anforderungen an die Leistungsfähigkeit von Mikrochips führen zu Halbleitertechnologien mit immer kleiner werdenden Strukturgrößen. Anwendungen mit hohen Ansprüchen an Sicherheit und Zuverlässigkeit, wie z.B. das autonome Fahren, treiben gleichzeitig die Anforderungen an den Test hochintegrierter Schaltungen an. Während des gesamten Lebenszyklus eines Mikrochips kommt es zu Unsicherheiten im Zeitverhalten. So können z.B. schwache Schaltungsstrukturen, Alterungseffekte oder Prozessvariationen zu einer Veränderung des Zeitverhaltens führen. Während diese Unsicherheiten nicht zu einer Veränderung des funktionalen Verhaltens führen müssen, können sie jedoch zu einem Zuverlässigkeitsproblem führen.\r\nMit der modularen und der hybriden Kompaktierung werden in dieser Arbeit zwei Testinstrumente vorgestellt, die für die X-tolerante Testantwortkompaktierung im eingebauten Hochgeschwindigkeitstest verwendet werden können. Eine Herausforderung für die Testantwortkompaktierung während des Hochgeschwindigkeitstests ist die hohe und variierende X-Rate an den Ausgängen der zu testenden Schaltung. Durch die Einteilung der Schaltungsausgänge in Prüfgruppen und die separierte Kompaktierung der Prüfgruppen mithilfe von stochastischen Kompaktierern, können die vorgestellten Verfahren diese hohen und variierenden X-Raten verarbeiten.\r\nFür den Umgang mit Unsicherheiten auf Verbindungsleitungen der Logik-Schaltung wird ein Verfahren zur Unterscheidung von Übersprechen und Prozessvariation vorgestellt. In aktuellen Halbleitertechnologien kommt es vermehrt zu parasitären Koppelkapazitäten zwischen den Verbindungsleitungen. In dem vorgestellten Verfahren werden künstliche neuronale Netze trainiert, um die Schaltungen in fehlerfrei und fehlerhaft zu klassifizieren." author: - first_name: Alexander full_name: Sprenger, Alexander id: '22707' last_name: Sprenger orcid: 0000-0002-0775-7677 citation: ama: Sprenger A.

Abgesehen von den konventionellen Methoden um einen Trojaner in eine Schaltung für ein Field-programmable Gate Array (FPGA) einzuschleusen, können auch die Entwurfswerkzeuge heimlich kompromittiert werden um einen Angreifer dabei zu unterstützen einen erfolgreichen Angriff durchzuführen, der zum Beispiel Fehlfunktionen oder ungewollte Informationsabflüsse bewirken kann. Diese Dissertation beschäftigt sich hauptsächlich mit den beiden Blickwinkeln auf Hardwaretrojaner in rekonfigurierbaren Systemen, einerseits der Perspektive des Verteidigers mit einer Methode zur Erkennung von Trojanern auf der Bitstromebene, und andererseits derjenigen des Angreifers mit einer neuartigen Angriffsmethode für FPGA Trojaner. Für die Verteidigung gegen den Trojaner ``Heimtückische LUT'''' stellen wir die allererste erfolgreiche Gegenmaßnahme vor, die durch Verifikation mittels Proof-carrying Hardware (PCH) auf der Bitstromebene direkt vor der Konfiguration der Hardware angewendet werden kann, und präsentieren ein vollständiges Schema für den Entwurf und die Verifikation von Schaltungen für iCE40 FPGAs. Für die Gegenseite führen wir einen neuen Angriff ein, welcher bösartiges Routing im eingefügten Trojaner ausnutzt um selbst im fertigen Bitstrom in einem inaktiven Zustand zu verbleiben: Hierdurch kann dieser neuartige Angriff zur Zeit weder von herkömmlichen Test- und Verifikationsmethoden, noch von unserer vorher vorgestellten Verifikation auf der Bitstromebene entdeckt werden.' - lang: eng text: The battle of developing hardware Trojans and corresponding countermeasures has taken adversaries towards ingenious ways of compromising hardware designs by circumventing even advanced testing and verification methods. Besides conventional methods of inserting Trojans into a design by a malicious entity, the design flow for field-programmable gate arrays (FPGAs) can also be surreptitiously compromised to assist the attacker to perform a successful malfunctioning or information leakage attack. This thesis mainly focuses on the two aspects of hardware Trojans in reconfigurable systems, the defenders perspective which corresponds to the bitstream-level Trojan detection technique, and the attackers perspective which corresponds to a novel FPGA Trojan attack. From the defender's perspective, we introduce a first-ever successful pre-configuration countermeasure against the ``Malicious LUT''-hardware Trojan, by employing bitstream-level Proof-Carrying Hardware (PCH) and present the complete design-and-verification flow for iCE40 FPGAs. Likewise, from an attackers perspective, we present a novel attack that leverages malicious routing of the inserted Trojan circuit to acquire a dormant state even in the generated and transmitted bitstream. Since the Trojan is injected in a post-synthesis step and remains unconnected in the bitstream, the presented attack can currently neither be prevented by conventional testing and verification methods nor by bitstream-level verification techniques. author: - first_name: Qazi Arbab full_name: Ahmed, Qazi Arbab id: '72764' last_name: Ahmed orcid: 0000-0002-1837-2254 citation: ama: Ahmed QA.

Heterogeneous compute nodes consist of computing resources such as CPU, GPU and FPGA and are the important components of the high-performance computing system that can adapt the automation to achieve the given goal. While implanting automation in the computing resources, management of the resources is one of the essential aspects that need to be taken care of. Tasks are continuously executed on the resources using its unique characteristics. Effective scheduling is essential to make the best use of the characteristics provided by each resource. Scheduling enables the execution of each task by allocating resources so that they take advantage of all the characteristics of the compute resources. Various scheduling heuristics can be used to create effective scheduling, which might require the execution time to schedule the task efficiently. Providing actual execution time is not possible in many cases; hence we can provide the estimations for the actual execution time . The purpose of this master's thesis is to design a predictive model or system that estimates the execution time required to execute tasks using historical execution time data on the heterogeneous compute nodes. In this thesis, regression techniques(SGD Regressor, Passive-Aggressive Regressor, MLP Regressor, and XCSF Regressor) are compared in terms of their prediction accuracy in order to determine which technique produces reliable predictions for the execution time. These estimations must be generated in an online learning environment in which data points arrive in any sequence, one by one, and the regression model must learn from them. After evaluating the regression algorithms, it is seen that the XCSF regressor provides the highest overall prediction accuracy for the supplied data sets. The regression technique's parameters also play a significant role in achieving an acceptable prediction accuracy. As a remark, when using online learning in regression analysis, the accuracy depends upon both the order of sequential data points that are coming to train the model and the parameter configuration for each regression technique. author: - first_name: Chinmay full_name: Kashikar, Chinmay last_name: Kashikar citation: ama: Kashikar C.
