The present invention is described in further detail.
Embodiment one, shown in Figure 1, the BOM deriving methods of the present embodiment comprise the following steps that：
Step 101：Start.
Step 102：Device is classified.
According to first three letter of device number, such as reading device numbering, device can be carried out according to device classification
Classification, then classified again in generic device by device encapsulation, so as to have identical device classification, identical device
The device of part encapsulation divides one kind into, referred to as similar device.And obtain similar number of devices, i.e., the number of device in similar device.
Specifically, device is first divided into resistance R, electric capacity C, inductance L, exclusion RN, switch SW, chip according to device classification
U, antenna ANT etc., then in generic device by device encapsulation classified, for example, by resistance R according to encapsulation be divided into R0201,
R0402, R0603, R0805 etc., are divided into C0201, C0402 etc. by electric capacity C according to encapsulation, and inductance L is divided into according to encapsulation
L0201, L0402 etc.；And R0201 quantity, R0402 quantity, C0201 quantity etc. are obtained respectively.
