The simulation of level 1 and level 2 trigger is steered by the routine CML1_TRG and CML2_TRG. The steering is controlled by the FF control card TRGP. The individual triggers are specified by separate key words, e.g., CTRI for calorimetric trigger, RPCT for RPC trigger etc. Trigger primitives are created for individual detector under the control of the same control card TRGP. For example the card
TRGP 'MUON' 1 'DTBT' 1will create the trigger primitive for all detectors of the muon system and will perform the trigger simulation for DTBX (one of the trigger systems of the muon, MTRI).
