Article
Full-text available
In order to match the strict reliability requirements mandated by regulations and standards adopted in the automotive sector, as well as other domains where safety is a major concern, the in-field testing of the most critical devices, including microcontrollers and systems on chip, is a crucial task. Since the controller area network (CAN) bus is w...

Nowadays, many electronic systems store valuable Intellectual Property (IP) information inside Non-Volatile Memories (NVMs). Designers widely use encryption mechanisms to enhance the integrity of such IPs and protect them from any unauthorized access or modification. At the same time, often such IPs are critical from a reliability standpoint. Thus,...

Nowadays, many electronic systems store valuable Intellectual Property (IP) information inside Non-Volatile Memories (NVMs). Therefore, encryption mechanisms are widely used in order to protect such information from being stolen or modified by human attacks. Encryption techniques can be used for protecting the application code, or sensitive sets of...

On 05 Feb. 2020, CARS Center held a seminar about the Research activities developed in the Center with a wide collaboration of PhDs, researchers and fellows. This was an unmissable opportunity to share knowledge and learn new skills.
Article
Full-text available
With the complexity of nanoelectronic devices rapidly increasing, an efficient way to handle large number of embedded instruments became a necessity. The IEEE 1687 standard was introduced to provide flexibility in accessing and controlling such instrumentation through a reconfigurable scan chain. Nowadays, together with testing the system for defec...
Chapter
In order to widen the spectrum of available products, companies involved in space electronics are exploring the possible adoption of COTS components instead of space-qualified ones. However, the adoption of COTS devices and boards requires suitable solutions able to guarantee the same level of dependability. A mix of different solutions can be cons...
Article
Full-text available
Nowadays, many Integrated Systems embed auxiliary on-chip instruments whose function is to perform test, debug, calibration, configuration, etc. The growing complexity and the increasing number of these instruments have led to new solutions for their access and control, such as the IEEE 1687 standard. The standard introduces an infrastructure compo...
Article
Software-based self-test (SBST) is being widely used in both manufacturing and in-the-field testing of processor-based devices and Systems-on-Chips. Unfortunately, the stuck-at fault model is increasingly inadequate to match the new and different types of defects in the most recent semiconductor technologies, while the explicit and separate targeti...
Article
Full-text available
Modern devices often include several embedded instruments, such as BIST interfaces, sensors, calibration facilities. New standards, such as IEEE Std 1687, provide vehicles to access these instruments. In approaches based on reconfigurable scan networks (RSNs), instruments are coupled with scan registers, connected into chains and interleaved with r...
Article
Safety-critical electronics components require thermal and electrical stress phases at the end of manufacturing test to screen weak devices. It is possible to optimize the stress induced during the screening phase of Burn-In by running in parallel different types of stress procedures. In previous works, stress procedures of CPU, RAM memory and FLAS...
Article
Full-text available
The cost of Burn-In is a major concern for the testing of Automotive Systems-on-Chip (SoC). This paper highlights problematic aspects of a Burn-In flow and describes a two-layered adaptive technique that permits to optimize the stress application and strongly reduce BI test time. At the SoC level, the described methodology adaptively copes with FLA...
Article
Full-text available
The cost of Burn-In is a major concern for the testing of Automotive Systems-on-Chip (SoCs). This paper proposes an optimized Test-During-Burn-In (TDBI) flow that takes advantage of the parallel execution of several types of stress procedures in which many components are carefully interleaved. The proposed methodology permits to significantly reduc...
Article
Full-text available
Nowadays, Self-Test strategies for testing embedded processors are increasingly diffused, especially for safety critical systems. Test programs can be effectively used for this purpose. This paper describes a set of systematic self-test techniques for in-order dual-issue embedded processors. The paper shows how to produce test programs suitable for...
Conference Paper
Full-text available
Thermal and electrical stress phases are commonly applied to automotive devices at the end of manufacturing test to give rise to early life latent failures. This paper proposes a new methodology to optimize the stress procedures during the Burn-In phase. In the proposed method, stress of CPU, RAM memory and FLASH memory are run in parallel using DM...
Article
The usage of electronic systems in safety-critical applications requires mechanisms for the early detection of faults affecting the hardware while the system is in the field. When the system includes a processor, one approach is to make use of functional test programs that are run by the processor itself. Such programs exercise the different parts...
Article
Software-based self-test (SBST) techniques are used to test processors and processor cores against permanent faults introduced by the manufacturing process or to perform in-field test in safety-critical applications. However, the generation of an SBST program is usually associated with high costs as it requires significant manual effort of a skille...
Conference Paper
The growing usage of electronic systems in safety-critical applications requires effective solutions to early identify possible faults affecting the hardware while it is in the operational phase. A possible approach leverages functional programs to be run by the CPU typically existing in such systems. These programs must exercise the different part...
Article
Multi-core systems are becoming particularly common, due to the high performance they can deliver. Their performance strongly depends on the availability of effective cache controllers, able to guarantee (among others) the coherence of the caches of the different cores. This paper proposes a method for the test of the cache coherence logic existing...
Conference Paper
It is well-known that faults affecting an electronic device may compromise its correct functionality, and industries have to check that their devices are fault-free before selling them. In case of a processor core, this task may be accomplished by running specially written "test" programs. In industrial embedded applications, however, shrinking suc...

Self-Test strategies for testing embedded processors are increasingly diffused. In this paper, we describe a set of self-test techniques tackling dual issue embedded processors. The paper details how to produce test programs suitable to detect stuck-at faults in computational modules belonging to dual issue processors. The proposed technique is aim...
Article
The increasing complexity of electronic components based on microprocessors and their use in safetycritical application - like automotive devices - make reliability a critical aspect. During the life cycle of such products, it is needed to periodically check whether the processor cores are working correctly. In most cases, this task is performed by...

Software-Based Self-Test is an effective methodology for devising the online testing of Systems-on-Chip. In the automotive field, a set of test programs to be run during mission mode is also called Core Self-Test library. This paper introduces many new contributions: (1) it illustrates the several issues that need to be taken into account when gene...
Article
The paper is dealing with the in-field test of the decode unit of RIS C processors through functional test programs following the SBST approach. The paper details a strategy based on instruction classification and manipulation, and signatures collection. The method does not require the knowledge of detailed implementation information (e.g., the net...
Article
When the result of a previous instruction is needed in the pipeline before it is available, a 'data hazard' occurs. Register Forwarding and Pipeline Interlock (RF&PI) are mechanisms suitable to avoid data corruption and to limit the performance penalty caused by data hazards in pipelined microprocessors. Data hazards handling is part of the micropr...
