Using built-in KiCad libraries in PCB Design - Cell-by-Cell Formula Trace

Sample Data

This table shows the count of components available in different built-in KiCad libraries.

Cell	Value
A1	Library Name
B1	Component Count
A2	Resistors
B2	120
A3	Capacitors
B3	95
A4	Connectors
B4	60
A5	ICs
B5	150

Formula Trace

=SUM(B2:B5)

Step 1: SUM(B2:B5)

Step 2: 120 + 95 + 60 + 150

Cells B2 to B5 are referenced to sum the total component count from built-in KiCad libraries.

Result

   A          B
1 Library   Component
  Name      Count
2 Resistors  120
3 Capacitors 95
4 Connectors 60
5 ICs        150
6 Total     425

The sum of components from all listed libraries is shown in cell B6 as 425.
