Goto

Pass block input to From blocks

Library

Signal Routing

Description

The Goto block passes its input to its corresponding From blocks. The input can be a real- or complex-valued signal or vector of any data type. From and Goto blocks allow you to pass a signal from one block to another without actually connecting them.

A Goto block can pass its input signal to more than one From block, although a From block can receive a signal from only one Goto block. The input to that Goto block is passed to the From blocks associated with it as though the blocks were physically connected. For limitations on the use of From and Goto blocks, see From. Goto blocks and From blocks are matched by the use of Goto tags, defined in the Tag parameter.

The Tag visibility parameter determines whether the location of From blocks that access the signal is limited:

• local, the default, means that From and Goto blocks using the same tag must be in the same subsystem. A local tag name is enclosed in brackets ([]).
• scoped means that From and Goto blocks using the same tag must be in the same subsystem or in any subsystem below the Goto Tag Visibility block in the model hierarchy. A scoped tag name is enclosed in braces ({}).
• global means that From and Goto blocks using the same tag can be anywhere in the model.

Note    A scoped Goto block in a masked system is visible only in that subsystem and in the subsystems it contains. Simulink generates an error if you run or update a diagram that has a Goto Tag Visibility block at a higher level in the block diagram than the corresponding scoped Goto block in the masked subsystem.

Use local tags when the Goto and From blocks using the same tag name reside in the same subsystem. You must use global or scoped tags when the Goto and From blocks using the same tag name reside in different subsystems. When you define a tag as global, all uses of that tag access the same signal. A tag defined as scoped can be used in more than one place in the model. This example shows a model that uses two scoped tags with the same name (A).

Data Type Support

A Goto block accepts real or complex signals of any data type, including fixed-point data types, except int64 and uint64.

Parameters and Dialog Box

Tag

The Goto block identifier. This parameter identifies the Goto block whose scope is defined in this block.

Tag visibility

The scope of the Goto block tag: local, scoped, or global. The default is local.

Corresponding From blocks

List of the From blocks connected to this Goto block. Double-clicking any entry in this list displays and highlights the corresponding From block.
