\begin{description}
\item[\class{Signal}]
For the full description of the \class{Signal} class, see
section~\ref{ref-sig}.
A signal is a trigger object. Whenever a signal changes value, the
generator is triggered.
\end{datadesc}
\begin{datadesc}{GeneratorType}
\item[\class{GeneratorType}]
\myhdl\ generators can be used as clauses in \code{yield}
statements. Such a generator is forked, while the original generator
waits for it to complete. The original generator resumes when the
forked generator returns.

In addition, as a special case, the Python \code{None} object can be
present in a \code{yield} statement:
\begin{description}

\item[\code{None}]
This is the do-nothing trigger object. The generator immediately
resumes, as if no \code{yield} statement were present. This can be
useful if the \code{yield} statement also has generator clauses: those
generators are forked, while the original generator resumes
immediately.
