Reference simulator API
***********************

Understanding how the reference simulator works
is important for debugging problems,
and implementing your own simulator.

In general, there are two steps to the reference simulator.
The first is a build step, in which a ``Network``
is converted into a ``Model`` which consists of
``Signals`` (values that can be manipulated)
and ``Operators`` (operations to be done on those values).
The second is the simulator, which runs
``Operator`` functions and collects probed data.
The simulator API is described in the
`user API <user_api.html>`_.

`Bekolay et al., 2014 <http://compneuro.uwaterloo.ca/publications/bekolay2014.html>`_
provides a high-level description
and detailed picture of the build process,
which may helpful.
