NA-MAAB — No recommendations
JMAAB — a, b
A minimum of one signal line shall connect two structural subsystems.
When a two-way signal connection exists between two structural subsystems (A and B), each direction shall be connected to at least one signal line.
Signals that are not used within a structural subsystem shall be input to a structural subsystem. These signals shall not be output to other structural subsystems or basic blocks.
Signals that are not used in the subsystem are connected to avoid crossing of signal lines.
Sub ID a:
Clarifies structural subsystem connections and execution order.
Sub ID b:
Eliminating unnecessary connections clarifies the relationship between connections.
Deviation from the rule can cause to confusion due to unused input/output signals.
