The essence of the described utility model is explained by the drawing (Fig. 1), which shows the structural diagram of a multifunctional device for testing programmable logic integrated circuits.

The personal control computer (PC) 1 is equipped with two modules of the multiplex channel of information exchange (MMCI) according to GOST R 52070-2003 and is connected to the interface board (IB) 4 using a cable, while the personal control computer (PC) 1 is equipped with a set of software: a terminal for manual and programmable control of the multiplex channel of information exchange, specialized technological programs for the corresponding type of block and module.

Depending on the tasks to be solved, the control and measuring equipment (CME) 3 may include combinations of an oscilloscope, a multichannel logic analyzer, a standard and special waveform signal generator, a frequency meter, while the CME is connected to the interface board (IP) 4 by cables.

The interface board (PS) 4 is a printed circuit board on which the power protection unit (PPU) 6, the analog signal switching unit (ASSU) 7, the indication unit (IU) 8, the operating mode control unit (OMCU) 9 and the contacting unit (CU) 10 are installed using soldering and screw connections.

The power protection unit (PPU) 6 is designed to monitor the connected power supply, protect against incorrect connection polarity and overvoltage, and generate the correct level of configuration signals for the programmable logic integrated circuit (PLIC) included in the test object (TO).

The indicator unit (IU) 8 is intended for visual display of the state of discrete static outputs and the state lines of the test object (TO) and is a set of LEDs, the number of which corresponds to the number of signals of the test object (TO). The indicator can be switched on/off forcibly by a switch on the interface board (IP) 4.

The analog signal switching unit (ASSU) 7 allows you to select a signal source individually for each analog input of the test object (TO), while the signal source can be the analog output of the test object (TO) or the control and measuring equipment (CME) 3.

The operating mode control unit (OMCU) 9 allows you to set an arbitrary network address of the test object (TO), send a general reset signal for the test object (TO), and change the configuration of the programmable logic integrated circuit (PLIC) included in the test object (TO).

The test object (TO) is a tested block or module containing a programmable logic integrated circuit, which is connected through the contact unit (CU) 10 to the interface board (IB) 4 using a cable.

The interface board (IP) 4 has a set of contact pads (CP) 11, wherein the contact pads are grouped by types, to which all available signals of the test object (TO) are sent.

Rigid fixation with bolted connections of the components of the multifunctional device is also necessary to ensure resistance to the effects of external mechanical factors during operation in field conditions. Cabinets of our own manufacture by Severny Press JSC or Rittal, Schroff, Zavod Energotekhnika LLC, etc. can be used as a cabinet for electronic equipment.

The multifunctional device for testing programmable logic integrated circuits operates as follows. The tested object (TO) is connected to the interface board (IB) 4 of the multifunctional device through the contact unit (CU) 10 using a cable. The tested object (TO) receives power supply +5 V, +15 V, -15 V through the power protection unit (PPU) 6, through the operating mode control unit (OMCU) 9 for setting the operating mode and is connected to the personal control computer (PCC) 1 and the control and measuring equipment complex (CMC) 3. Control actions on the tested object (TO) are given from the personal control computer (PCC) 1 through the interface board (IB) 4, by the corresponding control commands and external actions on the inputs of the tested object (TO). The response of the test object (TO) to control actions is recorded using special software installed on the personal control computer (PC) 1, control and measuring equipment (CME) 3, and, in some cases, can be visually monitored on the indicator unit (UI) 8. Based on the responses of the test object (TO) to control actions, the compliance of the tested unit and module with the requirements of the design documentation is confirmed, and the faulty component of the unit and module is determined. All available signals of the test object (TO) are sent to the contact pads of the set of contact pads (SCP) 11, located on the interface board (IP) 4, which allows for convenient connection of the control and measuring equipment (CME) 3 for detailed diagnostics.
