Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed
arrows point from an interface to procedures which implement that interface.
This could include the module procedures in a generic interface or the
implementation in a submodule of an interface in a parent module.
Where possible, edges connecting nodes are
given different colours to make them easier to distinguish in
large graphs.
Subroutines
private module subroutine cable_output_impl_end()
Module finalization procedure for cable_output_mod.
This procedure should be called at the end of the simulation after all
output has been written.
