Cadnet data

Since R2025a

Syntax

caddata = cadnetData(cadnetobj)

caddata = cadnetData(cadnetobj,Type=name)

Description

caddata = cadnetData(cadnetobj) returns data of cadnetobj.

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

Examples

Get Cadnet Data of a PCB

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

Create 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]
    EnableExactPadPerLayer: 1

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

cadnetobj — cadnet

object

The cadnet object specified as a string.

Example: caddata = cadnetData(cadnetname)

Data Types: string

Type — Type

all (default) | 'Surface' | 'Pins' | 'Vias' | 'Traces'

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

caddata — cadnet data

table

Returns cadnet object data.
