testsuite::test_poisson_ps_min_interval


Name:
testsuite::test_poisson_ps_min_interval - checks that intervals are independent of tic size
Synopsis:
(test_poisson_ps_min_interval) run -> minimum interal close to 0  

Description:
 
The inter spike interval (ISI) distribution of a Poisson process is
exponential. The test verifies that the minimum interval is arbitrarily
small and not constrained by the ms_per_tic property of the simlation kernel.
Remarks:
 
Even a correct implementation generates with low probability spike trains where the
minimal interval is larger than ms_per_tic. The seed set in the default configuration
of NEST avoids this problem. Therefore, failure of this script indicates that the
configuration is not portable.
