schedule_propagation_offset function

(Shortest import: from brian2.core.network import schedule_propagation_offset)

brian2.core.network.schedule_propagation_offset(net=None)

Returns the minimal time difference for a post-synaptic effect after a spike. With the default schedule, this time difference is 0, since the thresholds slot precedes the synapses slot. For the GeNN device, however, a post-synaptic effect will occur in the following time step, this function therefore returns one dt.

Parameters

net : Network

The network to check (uses the magic network if not specified).

Returns

offset : Quantity

The minimum spike propagation delay: 0*ms for the standard schedule but dt for schedules where synapses precedes thresholds.

Notes

This function always returns 0*ms or defaultclock.dt – no attempt is made to deal with other clocks.
