The functioning process of the inventive device for automated modeling and testing, we consider the example of modeling and testing of a digital goniometric navigation receiver of the global satellite navigation system GLONASS (navigation receiver, NP).

To ensure the process of automated modeling and testing of NPs, it is necessary to pre-set the reference values of the parameters of the functioning of the NPs in the storage unit of the reference parameters of operation 10. Enter the reference values of the parameters of the functioning of NPs by using the module for access to the reference parameters of functioning, which is an integral part of the storage unit of the reference parameters of functioning 10 .

The module for realizing access to the reference operating parameters, which is part of the storage unit of the reference operating parameters 10, provides the user with the following functionality:

- input of reference values of the NP functioning parameters and textual information about them through the graphical user interface;

-loading of reference values of operating parameters of NPs and textual information about them to an external array of hard magnetic disks at the user's command;

- unloading the reference values of the operating parameters of the NP and text information about them from the external array of hard magnetic disks to the comparison unit 9 (to the first information input) and the modeling report generator 11 (to the second information input) by the appropriate command from the control device 6.

In turn, the graphical user interface of the module for implementing access to reference functioning parameters, which is part of the storage block of reference functioning parameters 10, provides the user with the means to:

- enter the reference value of the parameter of the functioning of the NP;

- selection of the unit of measurement of the reference value of the parameter of the functioning of the NP from the list provided;

- choosing a method for comparing the reference value of the parameter of the NP functioning with the actual parameter of the NP functioning obtained as a result of modeling;

- selection of the priority of the reference value of the parameter of the functioning of the NP, which determines how critical the implementation of this parameter is to ensure the operability of the NP;

- issuing a command to download the reference values of the parameters of the operation of the NP on an external array of hard magnetic disks at the command of the user;

- issuing a command to unload the reference values of the parameters of the functioning of the NP from an external array of hard magnetic disks in the comparison unit 9 (to the first information input).

Before starting the modeling and testing process, the user of the automated modeling and testing device, through the graphical user interface of the module for accessing the reference operating parameters, which is part of the storage unit of the reference operating parameters 10, enters the reference values of the NP functioning parameters in accordance with the statement of work for the development of a navigation receiver. For each of the reference values of the parameters of the functioning of the NP, its numerical value, unit of measure, priority level of the parameter, a method of comparing the reference value of the parameter of functioning of the NP with the actual value of the parameter of functioning of the NP are introduced. After entering the reference values of the operating parameters of the NP, the user gives a command to download the reference values of the operating parameters of the NP to an external array of hard magnetic disks by clicking on the corresponding button on the graphical user interface of the module for access to the reference functioning parameters, which is part of the storage of the reference functioning parameters 10 .

After the process of entering the reference values of the parameters of the NP operation from the information storage device 3 to the information input of the simulation device 5, the simulation model of the navigation receiver is loaded by the appropriate command from the control device 6. Downloading the simulation model of the navigation receiver is carried out through the information bus 8. The process of modeling the NP starts according to the corresponding command from the control device 6 supplied to the control input of the simulation device 5.

Simulation device 5 simulates both individual elements of the navigation receiver (demodulators, amplifiers, analog-to-digital converters), and the NP as a whole and implements the NP model described using hardware description languages (in particular, VHDL and Verilog HDL languages), which can be deployed based on the Nallatech XtremeDSP Development Kit serial debugging tool using the Xilinx Virtex-4 XC4VSX35-10FF668 serial programmable logic integrated circuit.

The actual values of the parameters of the functioning of the NP generated by the simulation device 5 during the process of modeling the NP, as well as the log of the process of modeling the NP are transferred from the simulation device 5 to the information input of the information storage device 3 after the simulation of the navigation receiver by the appropriate command from the control device 6, filed on the control input of the simulation device 5. After which the actual values of the parameters of the navigation receiver, generate values during the simulation process are transferred from the information storage device 3 to the information input of the calculator 4 by the appropriate command from the control device 6, which is supplied to the control input of the information storage device 3.

In the calculator 4, mathematical processing of the actual values of the operating parameters of the NP obtained in the modeling process is performed, in particular, the calculation and construction are performed:

- statistical characteristics of phase shift measurements of radio navigation signals (standard deviation, relative and absolute errors, magnitude of the standard error, distribution characteristics of the measurement results);

- statistical characteristics of the calculation of the values of the angles of spatial orientation (standard deviation, relative and absolute errors, magnitude of the standard error, distribution characteristics of the calculation results);

- amplitude frequency characteristics of radio navigation signals;

- phase frequency characteristics of radio navigation signals;

- diagrams of the spectrum of radio navigation signals.

After the process of mathematical processing of the actual values of the parameters of the functioning of the NP in the calculator 4, the results of the mathematical processing of the actual values of the parameters of the functioning of the NP are transmitted to the information input of the information storage device 3 by the appropriate command from the control device 6, submitted to the control input of the calculator 4.

In the future, the results of mathematical processing of the actual values of the operating parameters of the navigation receiver are unloaded from the information storage device 3 by the appropriate command from the control device 6, submitted to the control input of the information storage device 3, and displayed on the monitor included in the PC, on the basis of which the input device is deployed - output and visualization of information 2, and thus become available for direct analysis by a user performing modeling and spytaniya navigation receiver.

The comparison unit 9 performs an element-wise comparison of the reference operating parameters obtained from the snoring unit 10 reference values of the NP functioning parameters with the results of mathematical processing of the actual values of the NP functioning parameters obtained through the first information input from the input-output device and information visualization 2.

The comparison of the reference values of the parameters of the functioning of the NP and the actual values of the parameters of the functioning of the NP is carried out in accordance with a predetermined method of comparing the reference value of the parameter of the functioning of the NP with the actual value of the parameter of the functioning of the NP, obtained after mathematical processing of the simulation results, determined by the user before the start of the modeling process through the graphical interface of the access implementation module to reference functioning parameters which is ostavnoy part of the reference parameters storage unit 10 functioning.

The result of comparing the reference values of the NP functioning parameters and the actual values of the NP functioning parameters is an array of binary values: 0 (the actual value of the NP functioning parameter does not correspond to the reference value of the NP functioning parameter) or 1 (the actual value of the NP functioning parameter corresponds to the reference value of the NP functioning parameter).

After the process of comparing the reference values of the parameters of the functioning of the NP and the actual values of the parameters of the functioning of the NP, the array of binary values is transmitted to the first information input of the modeling report generator 11, which implements the procedure for generating a report on modeling and testing, consisting of the substantive and requisite parts.
