Form Descriptions

Add Wire Name Form

Names specifies one or more names for wires. You can specify multiple names by separating each name with a space. You can also use a bus expression to name an array of wire names.

Font Height specifies the size of your wire name text as a floating-point value, in user units.

The default is 0.625.

Font Style specifies the typeface the system uses to display the wire name.

Justification specifies the position of the cursor with respect to the wire name.

Entry Style specifies the mechanism for placing the name with the wire.

fixed offset automatically positions the wire name at a specified distance from the wire.

manual requires you to place the wire name at a grid location on or near the wire.

Bus Expansion specifies how the system interprets bus names.

off (default) interprets the bus name as a single name and generates a single name that includes all the bits in the bus range. For example, for the name A<0:1>, the system generates only the name A<0:1>.

on interprets the bus name as multiple names and generates a name for each bit of a bus range that you specify in the Names field. For example, for the nameA<0:1>, the system generates names A<0> and A<1>.

Placement controls whether you can place multiple wire names automatically in one operation.

single (default) requires you to point and click to identify each wire name location.

multiple lets you drag your mouse between two points to designate the wires that you want the system to name automatically.

Purpose defines the purpose of the wire name.

label assigns the wire name to the corresponding wire.

alias defines the wire name as an alternative name (usually shorter or more descriptive) for the wire.

Show Offset Defaults expands the form so you can change the fixed offset values that the system uses for placing wire names on horizontal or vertical wires.

Text Offset specifies the distance between a wire name and a wire.
