# Command: 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.
