    Syntax

    caddata = cadnetData(cadnetobj)
    caddata = cadnetData(cadnetobj,Type=name)

    Description

    caddata = cadnetData(cadnetobj) returns data of cadnetobj

    example

    caddata = cadnetData(cadnetobj,Type=name) returns data of cadnet for a specified entity type.

    Examples

    Open Live Script

    Use the cadnetData function to get the cadnet 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

    Get the cadnet list

    Use the cadnet list function

    cadlist = cadnetList(pfile)
    cadlist=7×4 table
    CadnetIdx        CadnetName         NumPins    Length
    _________    ___________________    _______    ______

        1        {'Unconnected_Net'}       3           0 
        2        {'NET_OUTV'       }       2       0.615 
        3        {'NET_GND'        }       1        0.46 
        4        {'NET_IN22'       }       2       0.645 
        5        {'NET_IN11'       }       4       0.488 
        6        {'NET_INNEG'      }       2       0.515 
        7        {'NET_INPOS'      }       2       0.676

    Create a cadnet object

    Creeate a cadnet object of 'NET_IN11'

    cadobj = cadnet(pfile,"NET_IN11")
    cadobj = 
  cadnet with properties:

        pcBoard: [1×1 pcbFileRead]
     CadnetName: 'NET_IN11'
        NumPins: 4
    NumSurfaces: 2
        NumVias: 4
      NumTraces: 4
    TotalLength: 0.4880
        Voltage: 'NoDef'
     LayerRange: [1 3 5]
     EntityList: [1×1 struct]

    Get the cadnet data

    Use the cadnetData function

    cadnetData(cadobj)
    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 cadnet object specified as a string.

    Example: caddata = cadnetData(cadnetname)

    Data Types: string

    Optional entity type choice specified as a string. When Type is not specified cadnet data will be returned for all entities.

    Example: caddata = cadnetData(cadnetname,Type='Pins') returns cadnet data for cadnetobj specified as cadnetname for entity Type specified a 'Pins'.

    Data Types: string

    Output Arguments
