db_0110: Block parameters

Guideline Publication

Control Algorithm Modeling Guidelines - Using MATLAB^®, Simulink^®, and Stateflow^®

• Version 6.0

Sub ID Recommendations

• NA-MAAB — a

• JMAAB — a

MATLAB Versions

All

Rule

Sub ID a

Block parameters shall not be used to describe:

• Operation expressions

• Data type conversion

• Selection of rows or columns

• MATLAB commands

Custom Parameter

Not Applicable

Rationale

Sub ID a:

• Operation expressions, data type conversion, or row or column selection become a magic number in generated code, which makes consistency between the model and code difficult to maintain. Adjusting parameters also becomes difficult.

• Describing the calculation formula within the block decreases readability.

• The result of executing a MATLAB command is reflected in the code, which makes consistency between the model and code difficult to maintain.

Verification

Model Advisor check: Check usage of tunable parameters in blocks (Simulink Check)
