Check usable characters for parameter names

Check ID: mathworks.jmaab.jc_0232

Guideline: jc_0232: Usable characters for parameter names

JMAAB v5.1

Description

Checks if parameter names in a model adhere to the following guideline standards.

Contain only alphanumeric characters and underscores.
Do not begin with a number.
Do not begin or end with an underscore.
Do not have consecutive underscores.
Do not coincide with reserved MATLAB^® words.

Note

Reserved MATLAB words include the following:

Built-in functions: builtin
Functions in the MATLAB path: Functions List
Reserved Keywords (Embedded Coder)
nil
nan
inf
infinity

Reserved MATLAB words and variable names are case-insensitive.

This check requires a Simulink^® Check™ license.

Check Parameterization

This check contains sub-checks that correspond to sub IDs specified in the MAB and JMAAB modeling guidelines. You can use the Model Advisor Configuration Editor to specify which sub IDs (one or multiple) to execute.

For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:

NA-MAAB — a, b, c, d, e, f
JMAAB — a, b, c, d, e, f

Results and Recommended Actions

Guideline Sub ID	Condition	Recommended Action
jc_0232_a: Characters allowed for parameter names	One or more parameter names contain invalid characters.	Use only alphanumeric characters and underscores in parameter names.
jc_0232_b: Number at the beginning	One or more parameter names begin with a number.	Use alphabetic characters at the beginning of parameter names.
jc_0232_c: Underscore at the beginning	One or more parameter names begin with an underscore ("_").	Use alphabetic characters at the beginning of parameter names.
jc_0232_d: Underscore at the end	One or more parameter names end with an underscore ("_").	Do not end parameter names with underscores.
jc_0232_e: Consecutive underscores	One or more parameter names have consecutive underscores.	Do not use consecutive underscores in parameter names.
jc_0232_f: Single reserved MATLAB word	The parameter name is a reserved MATLAB word.	Do not use reserved MATLAB words as parameter names.

Capabilities and Limitations

Simulink semantics limit the use of parameter names that use invalid characters, or start with a number, underscore, or reserved MATLAB word.
Analyzes content of library-linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to graphical.
Supports exclusions of blocks or charts.
