// DESCRIPTION
//   This is a custom hierarchical channel that supports the notion of a
//   heartbeat function similar to a clock except it is more efficient
//   than an sc_signal<bool>. It may be used anywhere in the hierachy.
//   Modules using this channel should simply wait for one of the
//   defined events.
//
