This study explores how project-based learning in combination with other pedagogical scaffolding approaches influences students’ experiences during their transition into the university. Based on the thematic analysis of interviews with students at the end of the first semester, we show how a project-based course in electronics can create opportunit...

This paper describes a platform for obtaining and analyzing real-time measurements in Microgrids. A key building block in this platform is the Empirical Mode Decomposition (EMD) used to analyze the electrical voltage and current waveforms to identify the instantaneous frequency and amplitude of the monocomponents of the original signal. The method...

This paper presents a training arena to learn freshmen to communicate as an engineer, with special focus on written communication. We use two consecutive semesters for this training.
Article
Memories are one of the most universal cores that are embedded into almost all system on chips (SoCs). Finding cost effective test solution for embedded memories is paramount. Industries are still improving the existing low cost memory test solutions which can support current technologies and advanced SoC architectures. This paper presents a progra...
Conference Paper
Shared Cues is a password management system proposed by Blocki, Blum and Datta at Asiacrypt 2013. Unlike the majority of password management systems Shared Cues passwords are never stored, even on the management device. The idea of the Shared Cues system is to help users choose and remember passwords in a manner proven to avoid brute force searchin...
Conference Paper
The paper presents a novel four-semester course aimed at giving the students an identity as an electronics engineer and an innovative problem solver. The course shall also support and be supported by parallel Calculus and electronics courses.

“Experts in teamwork” is an obligatory subject for all master students at the Norwegian University of Science and Technology (NTNU). The students are organised in interdisci-plinary teams of 5 from at least 3 different study programmes solving real projects. They shall use their skills to solve the challenge, and learn to communicate with professio...
Article
The content addressable memory (CAM) based solutions are very useful in network applications due to its high speed parallel search mechanism. This paper presents a novel Ternary CAM (TCAM) based NAND Pseudo CMOS–Longest Prefix Match (NPC–LPM) search engine. The proposed system provides a simple hardware based solution using novel 11T TCAM cell stru...
Conference Paper
This paper presents an enhanced path delay fault simulator for combinational circuits. The main objective of this work is to improve the simulation time of path delay fault testing. Our experiments consider K-longest path sets of ISCAS'85 benchmark circuits, and 10M single input change (SIC) test patterns were applied and repeated ten times in orde...
Article
This paper presents a programmable built-in self-test (PBIST) methodology for embedded SRAMs. The BIST logic adapts the test controller with micro code encoding technique in order to control test operation sequences. The macro codes are used to select any of seven MARCH algorithms, and detect different faults of the memory under test (MUT). This BI...
Conference Paper
Delay faults in content addressable memories (CAMs) is a major concern in many applications such as network routers, IP filters, longest prefix matching (LPM) search engines and cache tags where high speed data search is significant. It creates the need for analysis of critical paths and detecting associated faults using minimum number of test patt...
Article
Embedded content addressable memories are very useful in many applications such as network switch, IP filters and longest prefix match search engine, where high speed search is essential. This makes it a necessity to find an efficient self-test methodology in order to measure its internal worst case search speed. This paper presents a pseudo CMOS l...
Conference Paper
This paper presents SIC based test stimuli with Arithmetic Built in Self-Test (ABIST) concept in order to detect the path delay faults. The presented generator with ABIST stimuli is quite useful for detecting the K-longest path-delay faults of the microprocessor. This paper extends the work of Ø. Gjermundnes and presents its application and validat...

Conference Paper
This paper presents novel cell structures for fully parallel static type binary content addressable memory (BCAM) with low power and high flexibility. The proposed CAM core cell structures eliminate the drawbacks and adapt the advantages of single bit line and dual bit line cell structures. In this work, the word match line (ML) structure of low po...

In this paper, we present the design of the readout and control circuitry for a four pixel digital camera to give the graduate students experience in analogue and digital integrated circuit design. The main objective of this design project is to give the students an insight into design methods used in the industry. This design project is also targe...
Conference Paper
The paper introduces experts-in-team (EIT), a novel approach to teaching students to work in interdisciplinary teams, and to learn how each of them influences the team and is influenced by the team. EIT was launched in the engineering degree programme at NTNU, and is now being extended to all master programs at the university. For the 2005 spring t...

This paper describes an undergraduate subject in the design of analog and digital CMOS integrated-circuits. This subject is of- fered for the students of Electronics in their 5th semester of the 10-semester master-programme. The emphasis is given on the mixed signal aspects of the IC design. The subject is a one-semester introductory subject in ana...
