1. A non-transitory computer-readable medium storing instructions, the instructions comprising: a plurality of instructions that, when executed by an electronic device, cause the electronic device to: provide two electronic diagrams, the two electronic diagrams including a first electronic diagram and a second electronic diagram, and each of the first electronic diagram and the second electronic diagram having blocks representing components of a system; determine corresponding features of the two electronic diagrams that are present in the first electronic diagram and the second electronic diagram; determine differences between the first electronic diagram and the second electronic diagram; provide, to a display device, an indication of the determined corresponding features and the determined differences, the indication being displayed by the display device; receive a selection of a section of the first electronic diagram, the selected section of the first electronic diagram being less than all of the first electronic diagram; identify a corresponding section of the second electronic diagram that corresponds to the selected section of the first electronic diagram; receive a selection of a merge direction indicating a direction in which at least one of the determined differences is to be copied between the first electronic diagram and the second electronic diagram; merge the at least one of the determined differences by copying the at least one of the determined differences in the selected merge direction: from the selected section of the first electronic diagram to the corresponding section of the second electronic diagram when the selected merge direction corresponds to a first direction, or from the corresponding section of the second electronic diagram to the selected section of the first electronic diagram when the selected merge direction corresponds to a second direction; and provide, to the display device, one of the first electronic diagram or the second electronic diagram into which the at least one of the determined differences was copied, the one of the first electronic diagram or the second electronic diagram being displayed by the display device.
