Digital integrated circuit, also known as digital chip, is a digital logic circuit or system that integrates components and wiring onto the same semiconductor chip. Digital integrated circuits are designed and operated based on digital logic (Boolean algebra) for processing digital signals.Integrated Circuit Chip is an integrate...[Detailed]

Current diagnosis technology can be divided into static current diagnosis and dynamic current diagnosis. The core of static current diagnosis technology is to compare the power supply current of the tested circuit in a stable operating state with a pre-set threshold to determine whether there is a fault in the tested circuit. It...[Detailed]

Due to the fact that the voltage logic value output by integrated circuits may not necessarily be related to all nodes in the circuit, voltage testing cannot detect non functional failure faults in integrated circuits. So, in the early 1980s, diagnostic techniques based on integrated circuit power supply currents were proposed. ...[Detailed]

The hardware defects of integrated circuit chips usually refer to the physical imperfections exhibited by the chips. Integrated circuit fault refers to a circuit logic functional error or abnormal circuit operation caused by an integrated circuit defect. The common factors that cause failures in integrated circuit chips include ...[Detailed]
