Abstract: An automatic detection circuit for an integrated circuit and an automatic detection method for the same are provided. The automatic detection circuit is suitable for a system-on-chip (SoC). A control unit of the automatic detection circuit enters an automatic detection mode to: switch a first dynamic switching circuit to connect a main bus to a virtual host circuit; switch a second dynamic switching circuit to connect memory interfaces and intellectual property circuit to a virtual input and output circuit; send detection vectors to the virtual host circuit to set and activate the memory interfaces and the intellectual property circuits; send the detection vectors to the virtual I/O circuit to replace external memory and external equipment for sending and receiving signals; and compare signals received by the virtual host circuit or signals received by the virtual input and output circuit with predetermined signal data to generate a detection result.

Abstract: A method and a system for recording an integrated circuit version are provided. The method is adapted to a register in an integrated circuit, which includes the following steps: recording the integrated circuit version with N bits, in which N is an integer greater than 1; and amending only a bit value of at least one bit selected from the N bits that have not been used for denoting any past integrated circuit version each time when the integrated circuit is revised.

Abstract: The present invention provides an auto-detection control apparatus, which receives an electric power from one of a system power source signal and an external device and performs a detection when coupled to the external device. The apparatus comprises a detection module, a power management module and a control module. The detection module generates a first result based on whether a first power signal from the external device exists, wherein the first result is related to whether the external device provides an electricity to itself. The power management module prevents a conflict between the system power source signal and the first power signal. The control module determines whether the electric power is supplied to the external device by the power management module based on the first result.

Abstract: An integrated circuit chip includes a core circuit, a first bond pad, a first switch circuit, a second configuration resistor, a control circuit, and a storage unit. The first bonding pad is coupled to a first external reference voltage through a first node, and the first node is coupled to the first external reference voltage through a bonding wire or a first configuration resistor. The first switch circuit is coupled between a first internal reference voltage and the first node. The second configuration resistor is coupled between the first internal reference voltage and the first switch circuit or between the first switch circuit and the first node. In a first mode, the control circuit turns on the first switch circuit, and writes a configuration state of the first bonding pad to the storage unit. In a second mode, the control circuit turns off the first switch circuit.
