We use the segments extensions (dxTarget & dyTarget) to enlarge if
needed the segments. This new implementation is completely at
Anabatic level and should not be seen (i.e. managed) at Katana level.
* Change: In AutoHorizontal & AutoVertical, change the semantic of
getSourceU() and getTargetU(). formerly they where the end
position of the segment (with extension included), now they
gives the position of the anchor contacts, that is the axis
of the perpandiculars.
* New: AutoSegment::getLength() is still a proxy toward the
Segment::getLength() which returns the length of segment with
dxSource & dxTarget. We introduce a getAnchoredlength()
which returns the length between the centers of the S/T
anchors. That is axis to axis.
This is this length which is now used througout Anabatic.
* New: In AutoSegment::_extentionCaps, add a fourth item to hold
the segment minimal length (to respect minimal area given
the wire width).
* New: In AutoSegment::getExtensionCap(), if the segment has
a non-zero S/T extension, returns it instead of the S/T
contact extension *if it is greated*. The check of the
extension can be disabled by the Flag::NoSegExt flag.
* Change: In AutoSegment::isMiddleStack(), security check on
the presence of source and targets. More accurate detection
of perpandicular in "same layer" with a non-zero length,
So the area is OK, even with a short segment.
* New: AutoSegment::expandToMinLength(), check if a segment is
under the minimal length and expand it if need be by playing
with the dxTarget & dxSource. Tag minimal segments with the
AutoSegment::SegAtMinArea flag. Also try to keep the segment
*inside* it's former (supposedly wider) interval.
* New: AutoSegment::unexpandToMinLength(), to be called on a
formerly minimal sized segment which as grown up. Reset
it's S/T extensions to zero and unset the flag SegAtMinArea.
* Change: In AutoHorizontal::updateOrient(), when the extension
are non-zero, also swap them if needed, to keep the exact
footprint of the segment.
* New: In AutoSegment::revalidate(), check that the segment
respect the minimal length (area), and expand it if needed.
Conversely, if the segment has grown up from a minimal
length state, reset it's extensions to zero.
* Change: In Anabatic::Session::revalidate(), invalidateds
segments are now sorted in such a way that the "middle stack"
ones are revalidateds last. Not recall 100% why...
* New: In Katana::TrackCost, add a computation of the free interval
length we are into (if any). Not used yet, keep it for future
use.
* Change: In KatanaEngine::finalizeLayout(), remove the call to
segments minimum area protection. It is now obsoleted by the
new implementation in Anabatic.
* Change: In Track::check(), call the minimum size/area checker
Track::checkMinArea().

Coriolis README
===============
Coriolis is a free database, placement tool and routing tool for VLSI design.
Purpose
=======
Coriolis provides several tools to perform the layout of VLSI circuits. Its
main components are the Hurricane database, the Etesian placer and the Katana
router, but other tools can use the Hurricane database and the parsers
provided.
The user interface <cgt> is the prefered way to use Coriolis, but all
Coriolis tools are Python modules and thus scriptable.
Documentation
=============
The complete documentation is available here, both in pdf & html:
./documentation/output/html
./documentation/UsersGuide/UsersGuide.pdf
The documentation of the latest *stable* version is also
available online. It may be quite outdated from the *devel*
version.
https://www-soc.lip6.fr/sesi-docs/coriolis2-docs/coriolis2/en/latex/users-guide/UsersGuide.pdf
Building Coriolis
=================
To build Coriolis, ensure the following prerequisites are met:
* Python 2.7.
* cmake.
* boost.
* bison & flex.
* Qt 4 or 5.
* libxml2.
* RapidJSON
* A C++11 compliant compiler.
The build system relies on a fixed directory tree from the root
of the user currently building it. Thus first step is to get a clone of
the repository in the right place. Proceed as follow: ::
ego@home:~$ mkdir -p ~/coriolis-2.x/src/support
ego@home:~$ cd ~/coriolis-2.x/src/support
ego@home:~$ git clone http://github.com/miloyip/rapidjson
ego@home:~$ git checkout ec322005072076ef53984462fb4a1075c27c7dfd
ego@home:~$ cd ~/coriolis-2.x/src
ego@home:src$ git clone https://www-soc.lip6.fr/git/coriolis.git
ego@home:src$ cd coriolis
If you want to use the *devel* branch: ::
ego@home:coriolis$ git checkout devel
Then, build the tool: ::
ego@home:coriolis$ make install
Coriolis gets installed at the root of the following tree: ::
~/coriolis-2.x/<OS>.<DISTRIB>/Release.Shared/install/
Where ``<OS>`` is the name of your operating system and ``<DISTRIB>`` your
distribution.
Using Coriolis
==============
The Coriolis main interface can be launched with the command: ::
ego@home:~: ~/coriolis-2.x/<OS>.<DISTRIB>/Release.Shared/install/bin/coriolis
The ``coriolis`` script detects its location and setups the UNIX
environment appropriately, then lauches ``cgt`` (or *any* command, with the
``--run=<COMMAND>`` option).
Conversely, you can setup the current shell environement for Coriolis by
using the helper ``coriolisEnv.py``, then run any Coriolis tool: ::
ego@home:~$ eval `~/coriolis-2.x/src/coriolis/bootstrap/coriolisEnv.py`
ego@home:~$ cgt -V
