Use Of Software Simulation Research Articles

FEATURES OF THE ORGANIZATION OF LABORATORY WORKS IN THE STUDY OF PHYSICS OF ELECTRICAL PHENOMENA USING SOFTWARE SIMULATORS

The article shows the possibility of convenient use of software simulators of electric circuits in performing laboratory works in physics, theory of electric circuits and signals, and the basics of electronics. An example of studying Kirchhoffʼs laws in the NI Multisim 14 simulator as one of the simplest in terms of interface but very powerful in terms of capabilities is considered. The choice of NI Multisim is due to the fact that it is de-facto one of the industrial standards in the real design of electronic devices. Thus, students are introduced to not an educational software simulator for modeling electrical phenomena, but to industrial software that they may have to deal with as future electronics designers.The article describes the structure of a typical mini-project (laboratory work) on the study of Kirchhoff's laws, and shows that this approach to organizing training is related to the specifics of teaching students majoring in 172 – “Telecommunications and Radio Engineering”, 123 – “Computer Engineering” and 125 – “Cybersecurity”.As a result, students acquire the skills to develop and test models of electrical circuits with visualization of the results obtained, learn to use the methods of solving systems of linear equations acquired in the course of mathematics in practice.
 Keywords: educational technologies of distance learning; simulation of electrical circuits; analysis of processes in electrical systems; use of NI Multisim 14 software package for educational purposes; laboratory works in physics and electronics; Ohm’s law; Kirchhoff's laws; virtual learning environment.

Biomimetic Signal Conditioning and Light Adaptation for Compound Vision Sensors

Previous research efforts in mimicking the compound eye of Musca domestica, the common house fly, in hardware have primarily been focused on optical designs to achieve the fast, analog, parallel processing, and motion hyperacuity properties of the biological system. While these optical platforms have shown promising results, nearly all proposed advantages of utilizing a fly-inspired sensor have been discovered through the use of software simulation with very little or no effort being made to validate these simulations using the actual fly-inspired optics. The work presented in this paper advances the frontier of compound vision research by mimicking the core processing systems of the fly's intermediate neural layer structure (the lamina) in hardware. The hardware designs were kept as biomimetic as possible, and the unique motion hyperacuity characteristic of Musca's visual system was preserved in each circuit design. It will be shown that an effective light adaptation system can be designed that is both analog and parallel by directly mimicking the fly's visual system. The proof-of-concept designs presented in this paper are an important first step in turning the novel compound optical designs of the past decade into useful sensors that can function in dynamic real-world environments.

Six-feature star-pattern identification algorithm

A six-feature all-sky star-field identification algorithm is developed. The minimum identifiable starpattern element consists of an oriented star triplet defined by three stars, their celestial coordinates, and their visual magnitudes. The performance of the star-pattern identification algorithm is verified through the use of software simulation.

Lazy simulation of digital logic

The use of software simulators as a means for developing and validating digital-logic systems has become well established, and the complexity of today's circuits makes the accuracy and efficiency of simulation of prime importance. It is suggested in the paper, however, that conventional simulation techniques are inadequate for this purpose: to represent the inherently parallel activity of a digital circuit in a sequential simulation program, an unnecessary, and often arbitrary, sequence of events is imposed. This is a process that is error-prone and inefficient. In an attempt to reason about the nature of the simulation problem, a model of hardware has been derived that makes use of the principles involved in functional programming; in particular, the concept of lazy evaluation has been adopted as a way of minimizing the amount of simulation activity required. This model has been used as the basis for the generation of several simulators, and the paper presents an analysis of the performance of such a lazy simulator in comparison with those of the more usual simulation mechanisms. The results of this are extremely encouraging.

The LOW RISC has been proposed as an HLL architecture for Prolog. This paper describes the development and use of software simulators for evaluation of the LOW RISC instruction set.

The Use of Software Simulators in the Testing and Debugging of Microprogram Logic

Recent trends in computer architecture have increased the amount of control logic (e.g., microinstructions) in digital systems, thus making testing and debugging a more formidable task. This correspondence discusses the needs and objectives of software simulators for testing and debugging microprogram logic, and discusses a simulator developed to aid the development of a large microprogrammed system.
