## Abstract

A system includes one or more data processors and a non-transitory computer-readable storage medium containing instructions which, when executed on the one or more data processors, cause the one or more data processors to perform operations. The operations include receiving a design schematic, extracting keywords from the design schematic, and sorting the design schematic by the extracted keywords. The operations further include extracting a part number of a component from the sorted design schematic, comparing the component associated with the part number with a reference component associated with the part number, and displaying a result of the comparison indicating whether the component and the reference component match.

## Claims

### Claim 1

A system, comprising:
one or more data processors; and
a non-transitory computer-readable storage medium containing instructions which, when executed on the one or more data processors, cause the one or more data processors to perform operations including:
