  The performance of several trigger counters based on plastic scintillators
with silicon photomultiplier readout is investigated with cosmic rays.
Efficiency and time resolution are measured using digital waveform analysis.
The obtained results are relevant for trigger subsystems of Multi-Purpose
Detector (MPD) and Baryonic Matter at the Nuclotron (BM@N) at the NICA
heavy-ion collider. The results show very high efficiency and good timing
performance of the counters.
