getantipads

Generate antipad stack

Since R2024a

Syntax

propVal = getantipads(pcbobject)

Description

propVal = getantipads(pcbobject) generates an antipads stack based on the number of signal vias and the number of conductive layers. propVal can be optionally customized and assigned to SignalViaAntipad.

This example shows how to use the getantipads function to generate an antipads stack

via = viaSingleEnded

via = 
  viaSingleEnded with properties:

                        GroundLayer: [3 5 9]
                          Conductor: [1x1 metal]

   Dielectric Layers
                          Substrate: [1x1 dielectric]

Input Arguments

collapse all

`pcbobject` — Single ended via
single ended via object (default)

Example: via=viaSingleEnded; propVal = getantipads(via)

Data Types: sigle ended via

Output Arguments

collapse all

`propVal` — antipads stack
antipads stack

getantipads returns an antipad stack of size SignalViaLocations-by- GroundLayer in the via. The first non-empty shape from obj.SignalViaAntipad is used for scalar expansion to build the antipad stack.
