Cimba Python

Cimba Python is a process-oriented discrete event simulation package backed by the Cimba C engine. It gives Python models native Cimba processes, queues, resources, random distributions, and time-weighted statistics while keeping the model code in Python.

If you are new to Cimba, start with Cimba in 10 Minutes. If you already know the basics, the Tutorial: Modeling with Cimba Python, Topical Guides, Examples, and API Reference sections are usually the shortest route to an answer.

A small example

import cimba


def clock(name):
    while True:
        cimba.hold(1.0)
        print(f"{cimba.time():.0f}: {name}")


with cimba.Simulation(seed=123) as sim:
    cimba.Process("Clock", clock, "tick").start()
    sim.stop_at(3.0)
    sim.execute()

This creates a simulation, starts a process, advances simulated time with cimba.hold(), and stops at an absolute simulation time.
