Sub ID Recommendations

• NA-MAAB — a, b

• JMAAB — a, b

MATLAB Versions

All

Rule

Sub ID a

Stateflow^® Chart (Stateflow) shall not have unconnected transitions.

Custom Parameter

Not Applicable

Example — Correct

Example — Incorrect

There are unconnected transitions.

Sub ID b

Stateflow Chart (Stateflow) shall not have unconnected exclusive (OR) states and connective junctions without a transition source.

Custom Parameter

Not Applicable

Example — Correct

Does not have unconnected exclusive (OR) states or connective junctions without a transition source.

Example — Incorrect

There are unconnected exclusive (OR) states and connective junctions without a transition source.

Rationale
