Abstract:

The current domestic automatic test system has problems such as poor real-time performance, test resource redundancy, and high cost. Based on the above problems, this paper proposes an automatic test system based on FPGA partial dynamic reconfiguration technology, which is based on FPGA dynamic reconfigurable technology combined with embedded The operating system realizes the dynamic management of test resources, and develops a hardware automatic test task programming model for the test process, which truly realizes the concurrent execution of the test process, thereby enhancing the real-time performance of the automatic test system test, thereby improving the accuracy and coverage of the test Sex. In the verification test, the dynamic reconfiguration test system is applied to the automatic test instance. The test results show that the hardware reconfiguration test task is loaded normally and the function of each test resource is executed correctly.
