Field name of global types

Customize generated field names of global types

Model Configuration Pane: Global Variables / Identifiers

Description

Customize generated field names of global types.

Dependencies

This parameter:

  • Appears only for ERT-based targets.

  • Requires Embedded Coder® when generating code.

Settings

$N$M (default) | string

Enter a macro that specifies whether, and in what order, certain text is to be included in the generated identifier. The macro can include a combination of the following format tokens.

TokenDescription
$A

Insert data type acronym into signal and work vector identifiers. For example, i32 for int32_t.

$H

Insert tag indicating system hierarchy level. For root-level blocks, the tag is the text root_. For blocks at the subsystem level, the tag is of the form sN_, where N is a unique system number assigned by the Simulink® software.

$M

Insert name-mangling text if required to avoid naming collisions.

Required.

$N

Insert name of object (block, signal or signal object, state, parameter or parameter object) for which identifier is being generated.

$U

Insert text that you specify for the $U token. Use the Custom token text parameter to specify this text.

Tips

  • Avoid name collisions in general. One way is to avoid using default block names (for example, Gain1, Gain2...) when your model has many blocks of the same type.

  • Where possible, increase the Maximum identifier length to accommodate the length of the identifiers you expect to generate. Reserve at least three characters for name-mangling text.

  • To control the case (upper or lower case) of the text that each token represents, include decorators such as [U_] in your macro. See Control Case of Identifiers by Using Basic Token Decorators.

  • The Maximum identifier length setting does not apply to type definitions.

  • This option does not impact objects (such as signals and parameters) that have a storage class other than Auto (such as ImportedExtern or ExportedGlobal).
