|
|
PlaceTop -- Places an instance at the top of the "reference instance"
|
|
|
|
\subsubsection{Synopsys}
|
|
|
|
\begin{verbatim}
|
|
PlaceTop ( ins, sym, offsetX, offsetY )
|
|
\end{verbatim}
|
|
|
|
\subsubsection{Description}
|
|
|
|
Placement of an instance.\\
|
|
\indent The instance has to be instantiated in the method \verb-Netlist- in order to use the \verb-PlaceTop- function.\\
|
|
|
|
\indent The bottom left corner of the abutment box of the instance is placed, after beeing symetrized and/or rotated, toward the top left corner of the abutment box of the "reference instance". The newly placed instance becomes the "reference instance".
|
|
|
|
\subsubsection{Parameters}
|
|
|
|
\begin{itemize}
|
|
\item \verb-ins- : Instance to place.
|
|
\item \verb-sym- : Geometrical operation to be performed on the instance before beeing placed.\\The \verb-sym- argument can take eight legal values :
|
|
\begin{itemize}
|
|
\item \verb-NOSYM- : no geometrical operation is performed
|
|
\item \verb-SYM_Y- : Y becomes -Y, that means toward X axe symetry
|
|
\item \verb-SYM_X- : X becomes -X, that means toward Y axe symetry
|
|
\item \verb-SYMXY- : X becomes -X, Y becomes -Y
|
|
\item \verb-ROT_P- : a positive 90 degrees rotation takes place
|
|
\item \verb-ROT_M- : a negative 90 degrees rotation takes place
|
|
\item \verb-SY_RP- : Y becomes -Y, and then a positive 90 degrees rotation takes place
|
|
\item \verb-SY_RM- : Y becomes -Y, and then a negative 90 degrees rotation takes place
|
|
\end{itemize}
|
|
\item \verb-offsetX- (optionnal) : An offset is put horizontally. The value given as argument must be a multiple of PITCH
|
|
\item \verb-offsetY- (optionnal) : An offset is put vertically. The value given as argument must be a multiple of SLICE
|
|
\end{itemize}
|
|
|
|
\subsubsection{Example}
|
|
|
|
\begin{verbatim}
|
|
Place ( myInst1, NOSYM, 0, 0 )
|
|
PlaceTop ( myInst2, SYM_Y )
|
|
\end{verbatim}
|
|
|
|
\subsubsection{Errors}
|
|
|
|
Some errors may occur :
|
|
\begin{itemize}
|
|
\item \verb-[Stratus ERROR] Placement : the instance doesn't exist.-\\The instance must be instanciated in order to be placed.
|
|
\item \verb-[Stratus ERROR] Placement : the first argument is not an instance.-
|
|
\item \verb-[Stratus ERROR] Placement : the instance is already placed.-\\One can not place an instance twice
|
|
\item \verb-[Stratus ERROR] PlaceTop : no previous instance.-\\One can use \verb-PlaceTop- only if a reference instance exist. Use a \verb-Place- call before.
|
|
\item \verb-[Stratus ERROR] PlaceTop : wrong argument for placement type.-\\The symetry given as argument is not correct.
|
|
\end{itemize}
