  • Configurable test environment for RTL simulation and performance evaluation of Network on Chip as part of SoC

    Nowadays, the System on Chip (SoC) industry is rapidly developing. One of the objectives of SoC developers is to provide the most efficient communication between computational units. One of the possible solutions is using Networks on Chip (NoC) of various topologies with different routing algorithms. In this paper, a configurable test environment designed for cycle-accurate NoC simulation as part of a SoC, used to provide statistics about network behavior during test process, is presented. The environment is designed to evaluate NoC performance as part of a specific SoC at the development stage, when there is a full or partial RTL description of the system. The environment configuration options, its application area, general scheme and calculated NoC performance characteristics are considered. As a conclusion, an example of using the environment to evaluate the performance of a specific NoC is described in detail.

  • Improvement of the friction absorbing device through the application of modern simulation methods and fabrication plate rolling

    The development of modern technology makes increasingly stringent requirements for materials, and improving the reliability and durability is an urgent task for many industries. One of the most important elements of the automatic coupling device of the car is the absorbing device. The parts included in it must meet high standards, be reliable and provide the necessary hardness and mechanical properties of the materials throughout the life cycle of the car. One of these parts included in the friction unit of the absorbing device is a movable plate. In the present work, an example of modernization of the absorbing apparatus through the use of modern methods of modeling and manufacturing of a fixed plate is given. The technical result is to reduce consumption of materials of the movable plate, and to simplify the manufacturing process of the plate by making it from rolled steel.
