μSim offers a lightweight and expressive user interface, built on top of a powerful and robust simulation framework. Using the async/await capabilities of Python3, μSim allows you to both quickly and reliably build even complex simulations.

>>> from usim import delay, run
>>>
>>> async def metronome(period: float, sound: str):
...     async for now in delay(period):
...         print(sound, '@', now)
...
>>> run(metronome(period=1, sound='tick'), metronome(period=2, sound='TOCK'), till=5)
tick @ 1
TOCK @ 2
tick @ 2
tick @ 3
TOCK @ 4
tick @ 4
tick @ 5
