Remove the automatic setting clock to be INPUT_STREAM_DERIVED. It should be managed by the controller.
Remove --workdir option and use the --logdir as the location for running as well as logs so that glitch files are dumped in the same place.
Ensure that clock master is reverted back to input stream derived in the auto test.
Create ascii-art rendition of the connections to aid debug.
