New quasi - 3D numerical model for thermal analysis of the BGA packages is presented. The general 3D heat transfer problem is correctly transformed to the set of 2D equations for temperature distributions in different layers of the package. The complexity and CPU time of the thermal analysis are many times reduced. The results of BGA package thermal modeling are presented.

The number of memory components in today's chips is increasing considerably. Through the limitations on area and number of test pins, it is not feasible to use a separate BIST architecture for testing every memory on the chip. Therefore, it is essential to have a configurable BIST architecture. In this paper, a configurable memory BIST architecture that can test different memories having different sizes and configurations with an arbitrary test algorithm is proposed.

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 BIST supports both the test and normal operation modes. The experimental results show that this work gives 17–47% improved area overhead and 16–41% enhanced speed compared to three published results.

In this paper a procedure of compaction a test set for combinational circuits is considered. The compaction procedure is oriented to a test set that represented as set of test cubes. The main idea of compaction a test cubes is to find all maximally compatible subsets by constructing decomposition tree. An irredundant cover of test cubes by all maximally compatible subsets allows finding minimal or close to minimal size of test pattern setting. Experimental results for benchmark circuits demonstrate the efficiency of the suggested compaction procedure.

The results of development of the techniques which form the scenario of target technology ≪Evidential independent verification of I&C Systems Software of critical application≫ and utilities of the scenario support at information, analytical and organizational levels are presented in the article. The result of the scenario implementation is the quantitative definition of latent faults probability and completeness of test coverage for critical software. This technology can be used by I&C systems developers, certification and regulation bodies to carry out independent verification (or certification) during modernization and modification of critical software directly on client objects without intruding (interrupting) in technological processes.

Design for Test (DFT) introduces certain elements such as buffers, inverter-pairs etc, though inconsequential, are integral part of a digital design. However, while debugging a circuit schematically, they waste precious real estate when a designer is mostly interested in the logical design elements. At the same time, it is important that these inconsequential elements are not discarded altogether as they could play an important role in the DFT debugging process such as buffer at pin output that fans out to multiple gates preserving the pin's hierarchical information when a design is flattened into primitives. This paper presents a novel approach that allows a designer to efficiently compact/un-compact inconsequential design components both completely/selectively in the design schematic, thus aiding the structural debugging process.

Maintaining constant performance in the presence of a set of changes in parameters and unwarranted events has become an essential aspect of present system designs. Knowing a predefined upper limit, for which a drop in performance is said to be satisfactory, enables autonomous systems to perform a control action to mitigate changes that violate such a predefined limit. This paper introduces an analytical model for optimisation of the maximum possible parameter fluctuations that permit robust operation.
