layerData

Layer data

Since R2025a

Syntax

layerdata = layerData(layerobj,Type)

Description

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

Examples

Get Layer Data of a PCB

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

layerobj — Input object

object

The input layer object specified as a string.

Example: layerdata = layerData(layername)

Data Types: string | fi

Type — Type

Surfaces | Pins | Traces | Vias

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

layerdata — Layer data

structure

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