    Syntax

    layerdata = layerData(layerobj,Type)

    Description

    layerdata = layerData(layerobj,Type) returns the object entities data.

    example

    Examples

    Open Live Script

    Use the layerData function to get layer data of 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

    Create layer object

    Create a layer object of metal layer 1

    layerobj = layer(pfile,1)
    layerobj = 
  layer with properties:

        pcBoard: [1×1 pcbFileRead]
    LayerNumber: 1
           Type: 'Pin'
    LayerHeight: 0.0184
    NumSurfaces: 1
        NumPins: 14
        NumVias: 4
      NumTraces: 21
     EntityList: [1×1 struct]

    Get layer data

    Use the layerData function

    layerData(layerobj)
    ans = struct with fields:
    Surfaces: [1×1 metalSurface]
        Pins: [1×1 pins]
        Vias: [1×1 vias]
      Traces: [1×1 traces]

    Input Arguments

    collapse all

    The input layer object specified as a string.

    Example: layerdata = layerData(layername)

    Data Types: string | fi

    The type, or types, data specified as one or more layer entities: Surfaces, Pins, Traces, Vias.

    Example: layerdata(layername,Type=['Pins','Vias']) shows layer data of layer object layername for entities'Pins' and 'Vias'.

    Data Types: string

    Output Arguments

    collapse all

    layerdata returns the layer data structure of a layer object for a specified entity Type.
