Backward Compatible Options
===========================

The following arguments can be used to create wiring plans equivalent to those
produced by old versions of SpiNNer.

.. note::
	
	These values are only provided for backwards compatibility (i.e. working with
	existing systems). It is highly recommended that new systems are built using
	the plans generated by ``--num-boards N``.

Old inter-frame spacing
-----------------------

Older multi-frame SpiNNaker machines use a different inter-frame spacing of
0.089 meters. Prior to SpiNNer version 2.3.0 this was the default. From Version
2.3.0 onwards a new inter-frame spacing default is 0.133 meters. To use the old
inter-frame spacing add the following argument to SpiNNer commands::

	--inter-frame-spacing=0.089
