Attributes

background_activity

Pseudo attribute; read/write access; type: float. Background activity per cycle

base_activity

Pseudo attribute; read/write access; type: float. Baseline activity per instruction

base_cycles

Pseudo attribute; read/write access; type: float. Baseline cycles per instruction

connections

Pseudo attribute; read-only access; type: [o*]. Example attribute, returns the connections
