Abstract: The present disclosure relates to a System On Chip (SOC)-oriented concurrent test system and method for multiple clock domains, and belongs to the technical field of chip detection. A board system of the present disclosure includes a board, and a clock domain controller, a slot bus controller and a test subsystem which are arranged on the board; the clock domain controller is connected to the test subsystem and the slot bus controller; the slot bus controller is connected to a backplane bus; and the test subsystem includes a test processor and a signal processing unit; the test processor includes a test pattern memory, a memory control, a timing generator, a pattern generator and a command generator. In the present disclosure, by means of a concurrent test method for multiple clock domains, the test efficiency of a single SOC is improved, and the test cost of the single chip is also reduced, thus increasing the benefit.

Abstract: The present disclosure discloses an automatic learning method and system for a digital test vector. The system includes an upper computer, a pattern generator PG, a driver DRIVER, a comparator COMPARE and a history random access memory HRAM. The method includes: writing a pattern file, the pattern file including an input pin timing and an output pin timing, wherein the input pin timing is provided by a device under test, and the output pin timing is configured to be in a learning state; running the pattern file, and recording a running state; reading recorded running state data, and acquiring an output pin state, recorded within certain time, in the running state data; and correcting the output pin timing in the running pattern file according to the acquired output pin state to obtain a corrected output timing, thus obtaining a corrected pattern file.

Abstract: The present disclosure discloses a multi-core test processor, and an integrated circuit test system and method. The multi-core test processor includes a co-test-processor-sync-controller, a master-test-processor, two or more co-test-processors, and a test subsystem command switching device. Several co-test-processors are introduced under the master-test-processor. The master-test-processor will deliver test patterns that require concurrent testing to the co-test-processors for execution, so as to complete test items similar to the asynchronous signal match test. After the co-test-processors complete the test, the master-test-processor continues to carry out the subsequent test. The present disclosure can achieve asynchronous concurrent test on multiple sites and improve the test efficiency. Meanwhile, idling of fewer test channels can be avoided when asynchronous test channels are allocated to each site, thereby improving test channel utilization rate.
