An automated test equipment for testing a device under test comprises an on-chip-system-test controller. The on-chip system test controller comprises at least one debug interface or control interface configured to communicate with the device under test. The on-chip-system-test controller optionally comprises at least one high bandwidth interface configured to communicate with the device under test. The on-chip-system-test controller is configured to control a test of a device-under-test which is a system-on-a chip.

A test site includes: at least one test module that tests a device under test; and a waveform data acquisition module that converts an electrical signal relating to the DUT into a digital signal with a predetermined sampling rate so as to acquire waveform data in the form of a digital signal sequence. The higher-level controller controls the at least one test module and the waveform data acquisition module, and collects the waveform data acquired by the waveform data acquisition module in a form associated with the operation state of the at least one test module.

A waveform data acquisition module includes an A/D converter that converts an electrical signal relating to a DUT into a digital signal, and a first memory unit that stores waveform data configured as a digital signal sequence. A function test module includes a test unit and a second memory unit. A higher-level controller instructs the waveform data acquisition module to start data sampling, and holds the time point thereof. Furthermore, the higher-level controller instructs the function test module to start to execute a pattern program, and records the time point thereof. The first memory unit records the time point at which the data sampling is started. The higher-level controller records the time point at which the execution of the pattern program is started.

The present disclosure provides a memory device test method, apparatus, and system, a medium, and an electronic device. The memory device test method includes: determining an operation path according to position coordinates of a target test platform and current position coordinates of a memory device; setting a movable apparatus according to the operation path, such that the movable apparatus moves the memory device into the target test platform according to the operation path; controlling the target test platform to test the memory device according to a target test program; and monitoring a test result of the memory device in real time, and storing the test result of the memory device into a database.

A method for detecting errors of a first field-programmable gate array (FPGA) program includes: receiving, by a monitoring program executed on a processor connected to an FPGA on which the first FPGA program is executed, a signal value read out from the first FPGA program; and comparing, by the monitoring program executed on the processor, the signal value to a reference value from a source other than the first FPGA program in order to detect errors of the first FPGA program.

Disclosed in some examples are methods, systems, memory devices, machine readable mediums configured to intentionally degrade NAND performance when a value of a NAND health metric indicates a potential for failure to encourage users to replace or backup their devices before data loss occurs. For example, the system may track a NAND health metric and when that metric reaches a predetermined threshold or state, the system may intentionally degrade performance. This performance degradation may be more effective than a warning to effect device backup or replacement.

A system on chip includes a one-time programmable (OTP) memory configured to store secure data, an OTP controller including at least one shadow register configured to read the secure data from the OTP memory and to store the secure data, a power management unit configured to receive an operation mode signal from an external device and to output test mode information indicating whether an operation mode is a test mode according to the operation mode signal and a test valid signal corresponding to the secure data, and a test circuit configured to receive the test mode information from the power management unit, to receive test data from the external device, and to output a scan mode signal and a test mode signal according to the test data and a test deactivation signal, wherein the test deactivation signal corresponds to development state data indicating a chip development state in the secure data.

An automated test equipment for testing one or more devices under test, comprises at least one port processing unit, comprising a high-speed-input-output interface, HSIO, for connecting with at least one of the devices under test, a memory for storing data received by the port processing unit from one or more connected devices under test, and a streaming error detection block, configured to detect a command error in the received data, wherein the port processing unit is configured to, in response to detection of the command error, limit the storing in the memory of data following, in the received data, after the command which is detected to be erroneous. A method and computer program for automated testing of one or more devices under test are also described.

A determination device includes an estimation circuit and a determination circuit. The estimation circuit generates estimation data by estimating input data in the n-th cycle based on the input data in cycles prior to the n-th cycle and a first generator polynomial. The determination circuit determines whether the input data and the estimation data match. The first generator polynomial is an arithmetic expression that sets the estimation data in the n-th cycle to an inverted value of the input data in (n?1)-th cycle if a logical sum of all the input data in a first period corresponding to a preset number of cycles prior to the n-th cycle is 0 or a logical product of all the input data in a second period corresponding to the preset number of cycles prior to the n-th cycle is 1, and sets the estimation data in the n-th cycle to the same value as the input data in the (n?1)-th cycle if the logical sum is not 0 and the logical product is not 1.
