Naming Considerations

ID: Title	hisl_0031: Model file names
Description	For model file names: Use these characters: `a-z`, `A-Z`, `0-9`, and the underscore `(_)`. Use strings that are more than 2 and less than 64 characters. (Not including the dot and file extension). Do not: Start the name with a number. Use underscores at the beginning or end of a string. Use more than one consecutive underscore. Use underscores in file extensions. Use reserved identifiers.
Rationale	Readability Compiler limitations Model-to-generated code traceability
Model Advisor Checks	Check model file name (Simulink Check)

References	ISO 26262-6, Table 1 (1h) 'Use of naming conventions'
Last Changed	R2018b
Examples	Recommended `My_model.slx` Not Recommended `_My__model.slx` `2018_01_11_model.slx` `New.slx`

ID: Title	hisl_0032: Model object names
Description	For the following model object names: Signals Parameters Blocks Named Stateflow^® objects (States, Boxes, Simulink^® Functions, Graphical Functions, Truth Tables) Use: These characters: `a-z`, `A-Z`, `0-9`, and the underscore `(_)`. Strings that are fewer than 32 characters. Do not: Start the name with a number. Use underscores at the beginning or end of a string. Use more than one consecutive underscore. Use reserved identifiers.
Notes	Reserved names: MATLAB^® keywords Reserved keywords for C, C++, and code generation. For complete list, see Reserved Keywords (Simulink Coder). `int8` , `uint8` `int16`, `uint16` `int32`, `uint32` `inf`, `Inf` `NaN`, `nan` `eps` `intmin`, `intmax` `realmin`, `realmax` `pi` `infinity` `Nil`
