The BOM Compare identifies changes in parts and part properties between the 2 designs. Note that NetBom considers the value of the selected BOM_IGNORE property described in the Configuration Variables to determine is a part is actually populated. A part can exist in the Part List, but it will not be populated if the selected BOM_IGNORE property is True.
A sample report can be viewed here: bom1_diff_bom2.txt
The reports summarize the following Differences between the 2 design Part Lists:
- Part Number Qty Changes
- Reference Designator Part Number Changes
- Deleted Reference Designators
- Added Reference Designators
- Changed Reference Designators
- Part Number Change Summary
- Property Difference Report
- Lab Rework Instructions(LRI) Report

-----------------------------------------------------------------------------------Reference Designator Part Number Changes
This report summarizes the Reference Designator Differences between Design1 and Design2. This could arise from one of the following conditions:
- RefDes is populated in Design 1 but not in Design2
- This includes the effect of the selected BOM_IGNORE property
- Line 8 below reports that C13 is in both designs, but the BOM_IGNORE property is TRUE in Design2
- R41 exists in Design1 but did not exist in Design2
- This includes the effect of the selected BOM_IGNORE property
- RefDes is not populated in Design 1 but is populated in Design2
- This takes into account the state of the selected BOM_IGNORE properties in both designs
- C84 is in both designs, but the BOM_IGNORE property is True in Design1 and False (or does not exist) in Design2
- This takes into account the state of the selected BOM_IGNORE properties in both designs
- RefDes has a different Part Number in Design1 than it had in Design2
- Line 19 below reports that PCB1 has a different part number in the 2 designs

This report highlights any parts that have the same Part Number in the 2 designs, but where a Key Part Property (selected from the KEY_PROP_LIST config variable as described in Configuration Variables was detected to be different in the two designs. NetBOM will detect if they properties changed for every instance (ALL_INSTANCES) of the part or will detail the affected Reference Designators if only some of the parts had property mismatches.

The BOM Compare identifies changes in parts and part properties between the two designs. Note that NetBom considers the value of the selected BOM_IGNORE property described in the Configuration Variables to determine if a part is populated or ignored. A part can exist in the part list, but it will not be populated if it exists in the BOM_IGNORE configuration.
The reports summarize the following differences between the two design part lists:
- Added Parts
- Deleted Parts
- Changed Parts
- Renamed Parts
- Part Quantity Changes
- Part Property Changes
For browser report help and information, see the Web Report Features documentation.
The report headers in this report, like all NetBom web browser reports, are customizable using the NETBOM_REPORT_SETTINGS CSET.
Note: if there is no net voltage property in the netlist, the net voltage is inferred from the net name using a highly customizable net name voltage extraction system. More information on this can be found in the NetBom Voltage Matching documentation.
