Raw Normal View History

* All Tools: - A complete sweep of cleanup to suppress allmost all compiler warnings. * ./crlcore: - New: Extented Python support for all objects needed to configure Coriolis. - New: Configuration files and load helpers completly written in Python. An XML emulation mode is still avalaible. - New: UsersGuide, as a replacement for README, written in ReST. - New: Start of Doxygen documentation (mostly for documenting the initialisation objects & methods).

\label{release-1-0-1475}%
}
This is the first preliminary release of the \DUrole{sc}{Coriolis 2} framework.
This release mainly ships the global router \DUrole{sc}{Knik} and the detailed router
\DUrole{sc}{Kite}. Together they aim to replace the \DUrole{sc}{Alliance} \DUrole{sc}{Nero} router.
Unlike \DUrole{sc}{Nero}, \DUrole{sc}{Kite} is based on an innovating routing modeling and ad-hoc
algorithm. Although it is released under \DUrole{sc}{gpl} license, the source code
will be avalaible later.

\item A graphical user interface (viewer only).
\item The \DUrole{sc}{Knik} global router.
\item The \DUrole{sc}{Kite} detailed router.

\DUrole{raw-latex}{\noindent} Supported input/output formats:
%
\begin{itemize}
\item \DUrole{sc}{Alliance} \DUrole{cb}{vst} (netlist) \& \DUrole{cb}{ap} (physical) formats.
\item Even if there are some references to the \DUrole{sc}{Cadence} \DUrole{sc}{lefdef} format, its
support is not included because it depends on a library only available
to \DUrole{sc}{Si2} affiliated members.

All configuration \& initialization files are Python scripts, despite their

between the system-wide configuration files and the user's configuration,
they may use the same Python helpers.

\DUtitle[note]{Note}
\emph{The loading policy is not hard-coded.} It is implemented
at Python level in \DUrole{cb}{coriolisInit.py}, and thus may be easyly be
amended to whatever site policy.
The truly mandatory requirement is the existence of \DUrole{cb}{coriolisInit.py}
which \emph{must} contain a \DUrole{cb}{coriolisConfigure()} function with no argument.

To ease the writing of configuration files, a set of small helpers
is available. They allow to setup the configuration parameters through
simple assembly of tuples.

\subsubsection*{\DUrole{sc}{Alliance} Helper%

The configuration file must provide a \DUrole{cb}{allianceConfig} tuple of
the form:

~~~~)
}
\end{quote}
\DUrole{raw-latex}{\noindent} The example above shows the system configuration file, with all the
available settings. Some important remarks about thoses settings:
%
\begin{itemize}
\item In it's configuration file, the user do not need to redefine all the settings,
just the one he wants to change. In most of the cases, the \texttt{SYSTEM\_LIBRARY},
the \texttt{WORKING\_LIBRARY} and the special net names (at this point there is not
much alternatives for the others settings).
\item \texttt{SYSTEM\_LIBRARY} setting: Setting up the library search path.
Each library entry in the tuple will be added to the search path according
to the second parameter:
%
\begin{itemize}
\item \DUrole{cb}{Environment::Append}: append to the search path.
\item \DUrole{cb}{Environment::Prepend}: insert in head of the search path.
\item \DUrole{cb}{Environment::Replace}: look for a library of the same name and replace
it, whithout changing the search path order. If no library of that name
already exists, it is appended.
\end{itemize}
A library is identified by it's name, this name is the last component of the
path name. For instance: \texttt{/soc/alliance/sxlib} will be named \texttt{sxlib}.
Implementing the \DUrole{sc}{Alliance} specification, when looking for a \emph{Cell} \texttt{name},
the system will browse sequentially trought the library list and returns
the first \emph{Cell} whose name match.
\item For \texttt{POWER}, \texttt{GROUND}, \texttt{CLOCK} and \texttt{BLOCKAGE} net names, a regular
expression (\DUrole{sc}{gnu} regexp) is expected.
\item The \texttt{helpers.sysConfDir} variable is supplied by the helpers, it is the
directory in which the system-wide configuration files are locateds.
For a standard installation it would be: \texttt{/soc/coriolis2}.
\item Trick and naming convention about \texttt{SYMBOLIC\_TECHNOLOGY}, \texttt{REAL\_TECHNOLOGY}
and \texttt{DISPLAY}. In the previous releases, thoses files where to read by
\DUrole{sc}{xml} parsers, and still do if you triggers the \DUrole{sc}{xml} compatibility mode.
But now, they have Python conterparts. In the configuration files, you
still have to name them as \DUrole{sc}{xml} files, the Python file name will be
deduced from this one with thoses two translation rules:
\setcounter{listcnt0}{0}
\begin{list}{\arabic{listcnt0}.}
{
\usecounter{listcnt0}
\setlength{\rightmargin}{\leftmargin}
}
\item In the filename, all dots, except for the last (the file extention),
are replaced by underscores.
\item The \texttt{.xml} extention is substituted by a \texttt{.conf}.
\end{list}
For the symbolic technology, it would give:
%
\begin{quote}{\ttfamily \raggedright \noindent
/soc/coriolis2/technology.symbolic.xml\\
~~~~~~~~~~~~~~~~~~~~~~~-{}->~/soc/coriolis2/technology\_symbolic.conf
}
\end{quote}
\end{itemize}
A typical user's configuration file would be:
%
\begin{quote}{\ttfamily \raggedright \noindent
import~os\\
~\\
homeDir~=~os.getenv('HOME')\\
~\\
allianceConfig~=~\textbackslash{}\\
~~~~(~('WORKING\_LIBRARY'~~~~,~homeDir+'/worklib')\\
~~~~,~('SYSTEM\_LIBRARY'~~~~~,~(~(homeDir+'/mylib',~Environment.Append)~)~)\\
~~~~,~('POWER'~~~~~~~~~~~~~~,~'vdd.*')\\
~~~~,~('GROUND'~~~~~~~~~~~~~,~'vss.*')\\
~~~~)

Taxonomy of the file:
%
\begin{itemize}
\item It must contains, at least, the two tables:
%
\begin{itemize}
\item \texttt{parametersTable}, defines \& initialise the configuration variables.
\item \texttt{layoutTables}, defines how the various parameters will be displayed
in the configuration window
\end{itemize}
\item The \texttt{parametersTable}, is a tuple (list) of tuples. Each entry in the list
describe a configuration parameter. In it's simplest form, it's a quadruplet
\DUrole{cb}{(TypeOption, 'paramId', ParameterType, DefaultValue)} with:
\setcounter{listcnt0}{0}
\begin{list}{\arabic{listcnt0}.}
{
\usecounter{listcnt0}
\setlength{\rightmargin}{\leftmargin}
}
\item \texttt{TypeOption}, tells that this tuple describe a parameter.
\item \texttt{paramId}, the identifier of the parameter. Identifiers are defined
by the tools. The list of parameters is detailed in each tool section.
\item \texttt{ParameterType}, the kind of parameter. Could be:
%
\begin{itemize}
\item \texttt{TypeBool}, boolean.
\item \texttt{TypeInt}, signed integer.
\item \texttt{TypeEnumerate}, enumerated type, needs extra entry.
\item \texttt{TypePercentage}, percentage, expressed between 0 and 100.
\item \texttt{TypeDouble}, float.
\item \texttt{TypeString}, character string.
\end{itemize}
\item \texttt{DefaultValue}, the default value for that parameter.
\end{list}

The \DUrole{sc}{Alliance} flow is based on the \DUrole{sc}{mbk} data-base, which has one data-structure
for each view. That is, \DUrole{cb}{Lofig} for the \emph{logical} view and \DUrole{cb}{Phfig} for the \emph{physical}
view. The place and route tools were responsible 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 \emph{logical} view is stored
in a \DUrole{cb}{vst} file in \DUrole{sc}{vhdl} format and the \emph{physical} in an \DUrole{cb}{ap} file in an ad-hoc format.
The \DUrole{sc}{Coriolis} flow is based on the \DUrole{sc}{Hurricane} data-base, which has a unified
structure for \emph{logical} and \emph{physical} view. That data structure is the \emph{Cell} object.
The \emph{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 use the \DUrole{sc}{Alliance} files format, but they now really represent
views of the same object. The point is that one must be very careful about
view coherency when going to and from \DUrole{sc}{Coriolis}.
As for the first release, \DUrole{sc}{Coriolis} can be used only for two purposes :
%
\begin{itemize}
\item \textbf{Routing a design}, in that case the \emph{netlist}
view and the \emph{layout} view must be present and \emph{layout} view must contain
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 unrouted placement
in the \emph{layout} view will be overwritten.
\item \textbf{Viewing a design}, the \emph{netlist} view must be present, if a \emph{layout}
view is present it still must have the same name but it can be in any
state.
\end{itemize}

The global router is (not yet) deterministic. To circumvent this limitation,
a global routing (also called a \emph{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
\DUrole{cb}{kgr} extention. It is in \href{http://www.cerc.utexas.edu/~thyeros/boxrouter/boxrouter.htm}{Box Router} output format.

\subsection*{Kite -{}- Detailed Router%
\phantomsection%
\addcontentsline{toc}{subsection}{Kite -{}- Detailed Router}%
\label{kite-detailed-router}%
}
\DUrole{sc}{Kite} no longer suffers from the limitations of \DUrole{sc}{Nero}. It can route big designs
as its runtime and memory footprint is almost linear (with respect to the number
of gates). It has successfully routed design of more than \DUroletitlereference{150K} gates.
\DUrole{raw-latex}{\medskip}
\DUrole{raw-latex}{\noindent} However, this first release has the following restrictions:
%
\begin{itemize}
\item Works only with \DUrole{sc}{SxLib} standard cell gauge.
\item Works always with 4 routing metal layers (\DUroletitlereference{M2} through \DUroletitlereference{M5}).
\item Do not allow (take into account) pre-routed wires on signals
other than \DUrole{sc}{power} or \DUrole{sc}{ground}.
\end{itemize}
After each run, \DUrole{sc}{Kite} displays a set of \emph{completion ratios} which must all
be equal to \DUroletitlereference{100\%} if the detailed routing has been successfull.
In the event of a failure, on saturated design, you may decrease the
\DUroletitlereference{edge saturation ration} (argument \DUroletitlereference{-{}-edge}) to balance more evenly the design
saturation. That is, the maximum saturation decrease at the price of a wider
saturated area and increased wirelength.
\DUrole{raw-latex}{\newpage}
Routing a design is done in three ordered steps:
\setcounter{listcnt0}{0}
\begin{list}{\arabic{listcnt0}.}
{
\usecounter{listcnt0}
\setlength{\rightmargin}{\leftmargin}
}
\item Global routing \DUrole{raw-latex}{\fbox{\textsf{\textbf{{P\&R}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{S}tep by Step}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{G}lobal Route}}}}}.
\item Detailed routing \DUrole{raw-latex}{\fbox{\textsf{\textbf{{P\&R}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{S}tep by Step}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{D}etailed Route}}}}}.
\item Finalize routing \DUrole{raw-latex}{\fbox{\textsf{\textbf{{P\&R}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{S}tep by Step}}}}} \DUrole{raw-latex}{$\rightarrow$} \DUrole{raw-latex}{\fbox{\textsf{\textbf{{\underline{F}inalize Route}}}}}.
\end{list}
After the detailed routing step the \DUrole{sc}{Kite} data-structure is still active.
The wiring is thus represented in a way that allows \DUrole{sc}{Kite} to manage it but
which is not completly finished. The finalize step performs the removal of
the \DUrole{sc}{Kite} data-structure and finish/cleanup the wiring so that its
connex in the sense of \DUrole{sc}{Hurricane}. \emph{Do not} try to save
your design before that step, you would get gaps in it.
The complete description of \DUrole{sc}{Kite} parameters are described in \hyperref[detailed-routing-configuration-parameters]{Detailed Routing Configuration Parameters}.

Python/Stratus scripts can be executed either in text or graphical mode.
\DUadmonition[note]{
\DUtitle[note]{Note}
\emph{How Cgt Locates Python Scripts.}
\DUrole{cb}{cgt} uses the Python \texttt{import} mechanism to load Python scripts.
So you must give the name of your script whitout \texttt{.py} extention and
it must be reachable through the \texttt{PYTHONPATH}. You may uses the
dotted module notation.
}
A Python/Stratus script must contains a function called \texttt{StratusScript}
with one optional argument, the graphical editor into which it may be
running (will be set to \texttt{None} in text mode).
Any script given on the command line will be run immediatly \emph{after} the
initializations and \emph{before} any other argument is processed.
Small example of Python/Stratus script:
%
\begin{quote}{\ttfamily \raggedright \noindent
from~status~import~*\\
~\\
def~doSomething~():\\
~~~~\#~...\\
~~~~return\\

~\\
~~doSomething()\\
~~return\\
~\\
if~\_\_name\_\_~==~"\_\_main\_\_"~:\\
~~StratusScript~()
}
\end{quote}
This script could be run directly with Python (thanks to the two last lines)
or through \DUrole{cb}{cgt} in both text and graphical modes.

\emph{What are Rubbers:} \DUrole{sc}{Hurricane} uses \emph{Rubbers} to materialize
physical gaps in net topology. That is, if some wires are missing to
connect two or more parts of net, a \emph{rubber} will be drawn between them

Installation from source is done differently than what is done in the packaging
procedure. The archive is also structured differently and meant to be unpacked
and compiled under a user's home directory.
Main building prerequisites:
%
\begin{itemize}
\item cmake
\item g++
\item boost
\item libxml2
\item yacc \& lex.
\item Qt 4
\item LEF/DEF (optional).
\item hMetis (optional).
\item doxygen.
\item latex
\item latex2html.
\item python-docutils (for reStructuredText).
\end{itemize}
Simple building procedure:
%
\begin{quote}{\ttfamily \raggedright \noindent
dummy@lepka:\textasciitilde{}\$~tar~jxvf~coriolis2-1.0-20121103.tar.bz2\\
dummy@lepka:\textasciitilde{}\$~cd~coriolis-2.x/src\\
dummy@lepka:src\$~./bootstrap/buildCoriolis.py~\textbackslash{}\\
~~~~~~~~~~~~~~~~~-{}-project=bootstrap~-{}-project=vlsisapd~-{}-project=coriolis~\textbackslash{}\\
~~~~~~~~~~~~~~~~~-{}-make="-j4~install"\\
dummy@lepka:src\$~./bootstrap/buildCoriolis.py~\textbackslash{}\\
~~~~~~~~~~~~~~~~~-{}-project=bootstrap~-{}-project=vlsisapd~-{}-project=coriolis~\textbackslash{}\\
~~~~~~~~~~~~~~~~~-{}-doc~-{}-make="-j1~install"
}
\end{quote}
Installation is done according to the following tree structure:

\end{longtable}
\DUadmonition[note]{
\DUtitle[note]{Note}
\emph{Alternate build types:} the \texttt{Release.Shared} means an optimized build
with shared libraries. But there are also available \texttt{Static} instead of \texttt{Shared}
and \texttt{Debug} instead of \texttt{Release} and any combination of them.
\texttt{Static} do not work because I don't know yet to mix statically linked binaries
and Python modules (which must be dynamic).

To simplify the tedious task of configuring your environment, a helper is provided
in the \texttt{bootstrap} source directory:
%
\begin{quote}{\ttfamily \raggedright \noindent
\textasciitilde{}/coriolis-2.x/src/bootstrap/coriolisEnv.py
}
\end{quote}
Use it like this:

\begin{quote}{\ttfamily \raggedright \noindent
