Variant End

Define end of bounded region

Since R2024a

• 

Libraries:
Simulink / Signal Routing

Description

The Variant End block defines the end of the bounded region that allows you to limit variant condition propagation without introducing a level of hierarchy. Define the start of the bounded region by using the Variant Start block. For every Variant Start block, there is a single corresponding Variant End block. When you specify the variant conditions on the Variant Start block, the corresponding Variant End block inherits the conditions and other parameters based on the unique Variant Start End Tag on compile.

Limitations

The Variant End block works with time-based, and action signals. You cannot use SimEvents^®, Simscape™ Multibody™, or other non-time-based signals with these blocks.

Ports

Input

Port_1 — Input branch

scalar | vector | matrix

Input branch that defines the end of the bounded region with the corresponding Variant Start block.

Data Types: single | double | half | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Port_N — Input port associated with Nth branch

scalar | vector | matrix

Input port associated with the Nth branch that defines the end of the bounded region with the corresponding Variant Start block.

Data Types: single | double | half | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Output

Port_1 — Output signal

scalar | vector | matrix

Output signal from the active variant.

Data Types: single | double | half | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Parameters

Variant Start End Tag — Unique identifier of bounded region

A (default) | valid MATLAB^® identifier

Unique identifier to identify the correct Variant Start and Variant End pair that form the bounded region, specified as a valid MATLAB identifier. A valid MATLAB identifier is a character vector of alphanumerics (A–Z, a–z, 0–9) and underscores, such that the first character is a letter and the length of the character vector is less than or equal to namelengthmax.

Programmatic Use

Block Parameter: VariantStartEndTag

Type: character vector

Values: 'A' | valid MATLAB identifier

Default: 'A'

Variant Paired Block — Option to highlight paired Variant Start block

off (default) | on

Select this parameter to highlight the Variant Start with the same Variant Start End Tag as the Variant End. If there are multiple Variant Start blocks with the same Variant Start End Tag, then the first block found is highlighted.

Programmatic Use

Block Parameter: VariantPairedBlock

Type: character vector

Values: 'off' | 'on'

Default: 'off'
