SimEvents

SimEvents is a discrete-event simulation engine for modeling distributed systems, logistics, and hardware architectures within the MATLAB and Simulink ecosystem.

Engineers use SimEvents to analyze system performance through discrete-event data like packet latency, buffer overflows, and resource contention. It operates by managing entities (data packets or physical goods) as they move through queues, servers, and switches. You can integrate it directly with Simulink control loops to simulate multi-domain designs (e.g., a flight controller interacting with a congested MIL-STD-1553 bus). By utilizing custom MATLAB functions for scheduling logic and statistical distributions for arrival rates, SimEvents provides the specific metrics needed to size hardware buffers or optimize supply chain throughput.
