Check usage of tunable parameters in blocks

Check ID: mathworks.maab.db_0110

Guideline: db_0110: Block parameters

Check whether tunable parameters specify expressions, data type conversions, or indexing operations.

To make a parameter tunable, you must enter the basic block without the use of MATLAB^® calculations or scripting. For example, omit:

Supported blocks include:

Available with Simulink^® Check™.

This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.

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

Condition	Recommended Action
Blocks have a tunable parameter that specifies an expression, data type conversion, or indexing operation.	In each case, move the calculation outside of the block, for example, by performing the calculation with a series of Simulink blocks, or pre-compute the value as a new variable.

Does not flag block parameters consisting of expressions with literals.
Runs on library models.
Analyzes content of library-linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in all masked subsystems. By default, the input parameter Look under masks is set to all.
Does not evaluate mask parameters.
Allows exclusions of blocks and charts.
