# Pipeline with 2 branches, the first one write random data into a file in $(growing_file_location).
# That branch is synchronized on the test clock that we drive in the scenario.
# The second branch reads it with giosrc and does some tests like waiting for the
# `done-waiting-signal` signals on the source etc...
#
# The whole dataflow is checked and we ensure that the exact same buffer content
# is read from the giosrc.
