[0002] In the current field of electronic product testing and verification, dynamic simulation testing is a key link in ensuring the performance and quality of electronic products.

[0003] However, traditional electronic product simulators often use fixed hardware circuits and fixed module configurations, which means they can only simulate specific electronic products or test systems. Whenever a new electronic product or test system appears, a new simulator needs to be redesigned and manufactured, which greatly limits the versatility of electronic product simulators.

[0004] Furthermore, existing traditional electronic product simulators usually have only limited communication interfaces and cannot communicate efficiently and stably with a variety of different integrated test systems, which not only affects the test efficiency but may also lead to test communication failures.

[0005] In addition, since the hardware and modules of traditional electronic product simulators are fixed, it is difficult to flexibly configure and adjust them according to actual needs. This increases the operating difficulty and time cost of testers and also limits the application of simulators in complex test scenarios.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the statement "comprise one..." do not exclude the presence of other identical elements in the process, method, article or equipment including the elements.

[0108] Obviously, the above embodiments of the present disclosure are merely examples for clearly illustrating the present disclosure, and are not limitations on the implementation methods of the present disclosure. For ordinary technicians in this field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present disclosure are still within the protection scope of the present disclosure.
