\section{Release Notes}
\subsection{Release 1.0.1363}
This the first preliminary release of the \CoriolisII framework.
This release mainly ships the global router \Knik and the detailed router
\Kite. Together they aims to replace the \Alliance \Nero router.
Unlike \Nero, \Kite is based on an innovating routing modeling and ad-hoc
algorithm. Although it has been developped under \GPL, the source code
will not be made avalaible until it has been properly published.
\medskip
\noindent Contents of this release:
\begin{enumerate}
\item A graphical interface (viewer only).
\item The \Knik global router.
\item The \Kite detailed router.
\end{enumerate}
\noindent Supported input/output formats:
\begin{itemize}
\item \Alliance \vst (netlist) \& \ap (physical) formats.
\item Even if there are some references to the \Cadence \LEFDEF format, it's
support is not included because it depends on a library only available
to \SiII affiliateds members.
\end{itemize}
\section{Installation}
Binary \rpm packages avalaibles:
\begin{center}
\begin{tabular}{|c|l|}

\hline
\end{tabular}
\end{center}
\section{Configuration}
Configuration of \CoriolisII no longer depends on environment variables.
All pathes and options are sets through \XML configuration files. The main
configuration file is~:
\begin{center}
\confcoriolisIIalc
\end{center}
Contents of this file should be familiar to all thoses already acquainteds
with \Alliance as the \XML node names takes back former shell environment
variables.
You may want to customize \CELLTOP to point where the \Alliance cells
libraries are installeds (\texttt{/usr/share/alliance}\ if you installed
the \Alliance package from \FEL.
All system settings can be overwritten by a \usercoriolisIIalc file in the
user's root directory.
\section{Tools}
\subsection{The \Hurricane Data-Base}
The \Alliance flow is based on the \MBK data-base, which have one data-structure
for each view. That is, \LOFIG for the \logical view and \PHFIG for the \physical
view. The place and route tools where responsibles for maintaining (or not) the
coherency between views. Reflecting this weak coupling between views, each one
was stored in a separate file with a specific format. The \logical view is stored
in a \vst file in \VHDL format and the \physical in an \ap file in an ad-hoc format.
The \Coriolis flow is based on the \Hurricane data-base, which have a unified
structure for \logical and \physical view. That data structure is the \Cell object.
The \Cell can have any state between pure netlist and completly placed and
routed design. Although the memory representation of the views has deeply
changed we still uses the \Alliance files format, but they now really represents
views of the same object. The point is that one must be very careful about
view coherency when going to and fro \Coriolis.
As for the first release, \Coriolis can be used only for two purposes~:
\begin{itemize}
\item \textbf{Routing a design}\xspace, in that case the \netlist\xspace
view must be present and the \physical view must be presents and contains
a placement. Both views must have the same name. When saving the routed design,
it is advised to change the design name otherwise the original placement
in the \physical view will be overwritten.
\item \textbf{Viewing a design}, the \logical view must be present, if a \physical
view is present it still must have the same name but it can be in any
state.
\end{itemize}
\newpage
\subsection{Knik -- Global Router}
The global router is (not yet) deterministic. To circumvent this limitation,
a global routing (also called a ``solution'') can be saved to disk and reloaded
for later uses.
A global routing is saved into a file with the same name as the design and a
\kgr extention. It is in \BoxRouterRef output format.
\noindent Menus~:
\begin{itemize}
\item \menu{P\&R}$\rightarrow$\menu{\underline{S}tep by Step}
$\rightarrow$\menu{Kite -- \underline{S}ave Global Routing}
\item \menu{P\&R}$\rightarrow$\menu{\underline{S}tep by Step}
$\rightarrow$\menu{Kite -- \underline{L}oad Global Routing}
\end{itemize}
\subsection{Kite -- Detailed Router}
\Kite no longer suffers from the limitations of \Nero. It can route big designs
as it's runtime and memory footprint is almost linear (with respect to the number
of gates). It has successfully routed design of more than \texttt{150K}\ gates.
\medskip\noindent
However, this first release has the following restrictions:
\begin{itemize}
\item Works only with \SxLib standard cell gauge.
\item Works always with 4 routing metal layers (\MII through \MV).
\item Do not allow (take into account) pre-routed wires on signals
other than \POWER or \GROUND.
\end{itemize}
\medskip\noindent
Routing a design is done in three ordered steps~:
\begin{enumerate}
\item Global routing \menu{P\&R}$\rightarrow$\menu{Kite -- \underline{G}lobal Route}
\item Detailed routing \menu{P\&R}$\rightarrow$\menu{Kite -- \underline{D}ailed Route}
\item Finalize routing \menu{P\&R}$\rightarrow$\menu{Kite -- \underline{F}inalize Route}
\end{enumerate}
After the detailed routing step the \Kite data-structure is still active.
The wiring is thus represented in a way that allow \Kite to manage it but
which is not completly finished. The finalize step perform the removal of
the \Kite data-structure and finish/cleanup the wiring so that it's
connex in the sense of \Hurricane. \textit{Do not}\xspace try to save
your design before that step, you would get gaps in it.
