This article describes an attempt to create open source LabVIEW software, equivalent to data collection and control software. The proposed solution uses GNU Radio, OpenCV, Scilab, Xcos, and Comedi in Linux. GNU Radio provides a user-friendly graphical interface. Also, GNU Radio is a software-defined radio that conducts experiments in practice using software rather than the usual hardware implementation. Blocks for data propagation, code deletion with and without code tracking are created using the zero correlation zone code (ZCZ, a combination of ternary codes equal to 1, 0, and –1, which is specified in the program). Unlike MATLAB Simulink, GNU Radio is open source, i. e. free, and the concepts can be easily accessed by ordinary people without much programming experience using pre-written blocks. Calculations can be performed using OpenCV or Scilab and Xcos. Xcos is an application that is part of the Scilab mathematical modeling system, and it provides developers with the ability to design systems in the field of mechanics, hydraulics and electronics, as well as queuing systems. Xcos is a graphical interactive environment based on block modeling. The application is designed to solve problems of dynamic and situational modeling of systems, processes, devices, as well as testing and analyzing these systems. In this case, the modeled object (a system, device or process) is represented graphically by its functional parametric block diagram, which includes blocks of system elements and connections between them. The device drivers listed in Comedi are used for real-time data access. We also present an improved PyGTK-based graphical user interface for GNU Radio.

The article proposes a variant of writing an algorithm for the operation of a device used in a field-programmable gate array on the example of random-access memory coding using the Verilog hardware description language. When performing the work, the Xilinx software is used, which allows working with the project at all stages of creating and describing the operation of the device logic. The practical significance of the work is the study and solution of the simplest problems in the development of modern radioelectronic rapid response devices in the Verilog hardware description language, such as coding a field-programmable gate array itself, writing test debugging code, setting input and output signals, sync pulse, reset and enable signals, describing the logic of devices such as counters, switches, registers and triggers, as well as simulating a finished project to assess the correct operation of the programmed device. This work can be used not only for teaching students of higher educational institutions in the field of development, debugging and coding of electronic and radio-electronic devices in terms of describing the algorithm of their work, but also for organizing laboratory work on courses of disciplines related to this topic, and for creating and designing real devices in production. The introduction and study of this programming language are conducted within the walls of one of the leading engineering universities of the Russian Federation — the Bauman Moscow State Technical University.
