R2026b

Component list

Since R2025a

Syntax

components = componentList(pfileobj)

Description

components = componentList(pfileobj) creates a component list.

Examples

Get Component List of a PCB

Use the componentList function to get a list of components in a pcb.

Read-in a pcb file

Use the pcbFileRead object to read in a file. Accepted file formats are:

• ODB++

• Allegro

• Native

Here we are using a native format file.

pfile = pcbFileRead('native_ExampleBoard_Allegro')

pfile = 
  pcbFileRead with properties:

           FileName: 'native_ExampleBoard_Allegro'
          NumLayers: 5
         MetalLayer: [1 3 5]
    DielectricLayer: [2 4]
        LayerHeight: [0.0184 0.0104 0.0092 0.0012 0]
         NumCadnets: 7
       NumPadStacks: 6
      NumComponents: 8
           NumParts: 5

Get the component list

Use the componentList function.

complist = componentList(pfile)

complist = 8×3 table
    ComponentIdx    ComponentName    NumPins
    ____________    _____________    _______

         1            {'OUT_V'}         1   
         2            {'U1'   }         6   
         3            {'C3'   }         2   
         4            {'R1'   }         2   
         5            {'TP1'  }         1   
         6            {'R2'   }         2   
         7            {'IN_N' }         1   
         8            {'IN_P' }         1
