Create Stranded Wire Form

The Create Stranded Wire command is used to create a wire comprising multiple strands in a single direction on a single net.

Field Description

Net Name

Specifies a net name for the current stranded wire. The stranded wire is added to the specified net. A new net is created if the one specified does not exist.

Environment variable: netName

Probe Nets

Creates probes for the selected or specified net (Layout XL and higher tiers).

Parameters

This section lets you specify the width, direction, and style for the wire that you want to create.

Strand Width

Specifies the width of each strand in the stranded wire.

Strand Number

Specifies the number of strands in each stranded wire.

Strand Spacing

Specifies the spacing between the individual strands of the stranded wire.

Begin Style

Controls how the stranded wire segment begins.

  • auto: Automatically sets the begin style of the stranded wire.
    • When the stranded wire is Manhattan in shape, its Begin Style is set to truncate.
    • Two orthogonal Manhattan wires will have their Begin Style and End Style set to extend in order to avoid notches.
    • When the stranded wire is diagonal in shape, its Begin Style is set to custom.
    • Two diagonal orthogonal stranded wires will have their Begin Style and End Style set to custom in order to avoid notches.
  • truncate: Creates a stranded wire with no begin extension.
  • extend: Creates a stranded wire with the default beginning extension value.
  • variable: Lets you override the value specified in the Begin field for the begin extension of a stranded wire.
  • custom: Creates a stranded wire in which the vertices are constrained to the current grid.

The default value is auto.

Environment variable: pathSegBeginStyle

Begin

Specifies the value for the begin extension of the stranded wire. This field is enabled when Begin Style is set to variable.

Environment variable: pathSegBeginExt

End Style

Controls how the beginning wire segment ends are created.

  • auto: Automatically sets the end style of the wire.
    • When the stranded wire is manhattan in shape, its Begin Style is set to truncate.
    • Two orthogonal manhattan stranded wires will have their Begin Style and End Style set to extend in order to avoid notches.
    • When the stranded wire is diagonal in shape, its End Style is set to custom.
    • Two diagonal orthogonal stranded wires will have their Begin Style and End Style set to custom to avoid notches.
  • truncate: Creates a stranded wire with no begin extension.
  • extend: Creates a stranded wire with the default begin extension value.
  • variable: Lets you override the value specified in the Begin field for the begin extension of a wire.
  • custom: Constraints the vertices of the created wire to the current grid.

The default value is auto.

Environment variable: pathSegEndStyle

End

Specifies the value for the end extension of the stranded wire. This field is enabled when End Style is set to variable.

Environment variable: pathSegEndExt

Creation Mode

The following options let you specify the snapping behavior for the stranded wire that you want to create.

Snap Mode

Controls how the cursor snaps when you create the stranded wire.

  • orthogonal: Creates wires parallel to the X or Y axis. This is the default option.
  • diagonal: Generates a warning message informing the user that only orthogonal stranded wires are supported. The mode is automatically changed to orthogonal.

Environment variable: snapMode

Auto Terminate

Finishes the Create Stranded Wire command as soon as a point is digitized on a flightline target object (pin or existing wire or via). When creating a stranded wire and Auto Terminate is on, all stranded wires snap to its target pin. This option is selected by default.
