“…Research in this area has been extensive, and there are many studies reported in the world and particularly in Europe. A PIL simulation system was developed in [11], which has led to the full testing and validation of the GNC flight code to be ported to a VxWorks environment in a PowerPC8245 board, representative of the onboard computer, while a Field Programmable Gate Array (FPGA)-based PIL simulation test bench for the proposed machine was set up in [12]. Furthermore, [13] shows how to implement PIL and the preliminaries to HIL of electronic/electric systems with easy access technology through a code generation tool called Xilinx System Generator, an FPGA device, and a personal computer.…”

The digital signal processing (DSP) processor-in-the-loop tests based on automatic code generation technology are studied. Firstly, the idea of model-based design is introduced, and the principle and method of embedded code automatic generation technology are analyzed by taking the automatic code generation of the DSP control algorithm for pulse width modulation (PWM) output as an example. Then, the control system model is established on MATLAB/Simulink. After verifying the model through simulation, the target board platform is established with DSP as the core processor, and the automatically generated code is tested by the processor-in-the-loop (PIL). The results show that the technology greatly shortens the development cycle of the project, improves the robustness and consistency of the control code, and can be widely used in the complex algorithm development process of the controller, from intelligent design and modeling to implementation.

“…The two FPGAs communicate using analog IOs for measuring the currents and voltages and digital IOs for sending the PWM signals and fetching the simulated resolver data [6][7]. Practically, replacing the test-bench with its digital twin becomes seamless from the controller's point of view.…”

The paper focuses on implementation of several different concepts of wise analysis of light electric vehicle propulsion unit testing facility. Firstly, the concept of "digital twin" that represents a simulated replica of a complete testing facility is presented. More, instead of using an off-line simulation environment, the digital twin (DT) is programmed to run using two field programmable gate arrays (FPGA), hence it becomes an online real-time simulation. The second concept is the distribution of the digital twin. The actual unit controller is programed into one FPGA and the machine under test, its load and the power inverter are implemented into a second FPGA. The communication between the two is handled using analog and digital lines, just like the controller would be connected to the real test-bench. The third concept involves the organization of each of the two FPGA programs, based on Energetic Macroscopic Representation (EMR) that facilitates transparency, ease of implementation and minimizes the error in coding the actual test-bench replica and then its controller. Combining all the above mentioned concept into one single lucrative tool, experimentally validated by actual measurements, proves that the concept of using a DT implemented in real-time, without doubt can be used for testing prototypes and their controls regardless of the actual test-bench. Hence, on one hand it is eco-friendly, precise and save testing method and on the other hand, the same DT can be used by researchers and testers in facilities that do not have a test-bench at their disposal.
