\subsubsection{Handling shorted inputs}
\begin{frame}{\subsubsecname}
TBD
\begin{itemize}
\item The special parameters {\tt \_TECHMAP\_BITS\_CONNMAP\_} and
{\tt \_TECHMAP\_CONNMAP\_\it <port-name>\tt \_} can be used to handle shorted inputs.
\medskip
\item Each bit of the port correlates to an {\tt \_TECHMAP\_BITS\_CONNMAP\_} bits wide
number in {\tt \_TECHMAP\_CONNMAP\_\it <port-name>\tt \_}.
\medskip
\item Each unique signal bit is assigned its own number. Identical fields in the {\tt
\_TECHMAP\_CONNMAP\_\it <port-name>\tt \_} parameters mean shorted signal bits.
\medskip
\item The numbers 0-3 are reserved for {\tt 0}, {\tt 1}, {\tt x}, and {\tt z} respectively.
\medskip
\item Example use-cases:
\begin{itemize}
\item Detecting shared clock or control signals in memory interfaces.
\item In some cases this can be used for for optimization.
\end{itemize}
\end{itemize}
