Computing device and method for viewing relevant circuits of signal on circuit design diagram

A computing device, comprising:

• at least one processor;
• and
• a storage system storing a plurality of instructions, which when executed by the at least one processor, cause the at least one processor to:
• read a circuit design diagram of a printed circuit board (PCB) stored in the storage system;
• determine a state of each signal of the PCB on the circuit design diagram using an image matching algorithm and obtain one or more sub circuit design diagrams of the signal from the circuit design diagram according to the state of the signal on the circuit design diagram;
• store the state and the sub circuit design diagrams of each signal into the storage device;
• read a circuit testing program of the PCB from the storage system;
• determine a specific signal of the PCB when a testing instruction is selected from the circuit testing program, and retrieve sub circuit design diagrams of the determined signal from the storage device;
• and
• display the sub circuit design diagrams of the determined signal on a display device.
