    Syntax

    stackup = stackUp(pfileobj)
    stackUp(pfileobj,LayerNumber)

    Description

    stackup = stackUp(pfileobj) returns the material details of all layers in the board.

    example

    stackUp(pfileobj,LayerNumber) returns the material details of a specified layer or multiple layers.

    Use the stackUp function to get material information of a read-in pcb file

    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 stackUp data for all layers

    Use the stackUp function to get the material information for the pcb
