testsuite::test_iaf_i0_refractory - sli script for test of iaf_psc_alpha internal DC currentSynopsis:
(test_iaf_i0_refractory) run -> compare cout with comments in fileDescription:
test_iaf_i0_refractory.sli is a test of a specific feature of the
iaf_psc_alpha model. It is tested whether the voltage traces of simulations
carried out at different resolutions (computation step sizes) are well
aligned and identical when the neuron recovers from refractoriness.
In grid based simulation a prerequisite is that the spike is reported at
a grid position shared by all the resolutions compared.
Here, we compare resolutions 0.1, 0.2, 0.5, and 1.0 ms. Therefore, the
internal DC current is adjusted such (1450.0 pA) that the spike is
reported at time 3.0 ms, corresponding to computation step 30, 15, 6,
and 3, respectively.
The results are consistent with those of iaf_psc_alpha_canon capable of
handling off-grid spike timing when the interpolation order is set to
The expected output is documented and briefly commented at the end of
The file is an extended version of test_iaf_i0.sli .
