Name:

    testsuite::test_iaf_dc_aligned_stop - sli script for test of iaf_neuron resolution independence

Synopsis:

    (test_iaf_dc_aligned_stop) run -> compare response with reference data

Description:

      test_iaf_dc_aligned_stop.sli is an extended version of
      test_iaf_dc_aligned_delay.sli . In addition to the time when the
      current is switched on (/start) (test_iaf_dc_aligned_delay.sli) also
      a finite duration of the current is specified. This is done by
      supplying the DC generator device with the time stamp of the
      earliest DC event that should not be emitted.  Consequently, stop =
      start + duration.

      In the step stop	- h -> stop, no DC event is emitted anymore. A neuron
      connected to the DC generator interprets this as a DC current that is
      switched off precisely at time stop. Therefore, the DC current specified
      by start and stop is independent of the resolution h. The minimal duration
      is h.

      See [1] for details on why the DC generator specification is
      consistent with a grid based integration scheme of systems of
      differential equations.  In this scheme DC currents are represeted
      by the differential equation d/dt I = 0.

      The resulting SLI code is independent of the resolution and
      generates exactly the same voltage trace at all resolutions.

      No output of the spike detector is visible here because of the short
      stimulation period of 2 ms.

      The expected output is documented at the end of the script.
