A method, system, and related component for detecting properness of a PG pin power-on timing sequence are provided. The method comprises: obtaining a pull-up level of a PG pin of a VR chip (S101); determining a value of a pull-up resistor of the PG pin, as a first resistance, when a current injected into the VR chip by using the pull-up level is equal to a maximum withstand current of the VR chip (S102); obtaining an equivalent resistance to ground when the PG pin is at a low level, and calculating, based on the equivalent resistance to ground, a value of the pull-up resistor of the PG pin, as a second resistance, when an output voltage of the PG pin is equal to a preset interference voltage limit value (S103); and outputting first prompt information when it is determined that an actual resistance of the pull-up resistor is lower than the first resistance or the second resistance (S104). The foregoing solution is applied, to determine whether a power-on timing sequence of PG pins in a VR chip is proper, thereby avoiding an incorrect action of a subsequent circuit.

In one aspect, a programmable circuit includes: (1) a superconducting component arranged in a multi-dimensional array of alternating narrow and wide portions, the superconducting component having an input terminal at a first end and an output terminal at a second end opposite of the first end; and (2) control circuitry coupled to the narrow portions of the superconducting component, the control circuitry configured to transition the narrow portions between superconducting and non-superconducting states. In some implementations, the superconducting component and the control circuitry are formed on different layers of the programmable circuit.

A programmable integrated circuit device able to be selectively programmed to perform one or more logic functions includes multiple configurable logic blocks (“LBs”), routing fabric, and a nonvolatile memory (“NVM”).
