Design of Circuit Board Schematic Validating System Based on Virtual Instrument

When the circuit board schematic of spare parts are hardly obtained, it is of importance and significance that circuit board schematic validating system is designed, by which the circuit board schematic is calibrated and the spare parts can be designed and produced. On the basis of the combination of virtual instrument and developed in this paper, a circuit board schematic validating system is designed. Virtual instrument and its architecture are narrated in brief firstly. Then the system software design is developed. By applying the data acquisition cards, and Labview, the virtual instrument is built to schematic validating. The method used in this research can also be used another similar calibration systems.
