* Change: In NetBuilder::getPositions(), ordering of source/target points
is now integrated to this function instead of left to the caller.
In case of real (non-symbolic) routing gauge, skrink the ends of
half the wire width.
* Change: In NetBuilderHV::doRp_AutoContacts(), in case of non-METAL1
RoutingPad, put the axis of the segment on the nearest track.
Issue a warning if we have to shift, as it may be a potential
source of routing problems.
* New: Anabatic::Session::getNearestTrackaAxis(), proxy to compute
track positions, knowing the design abutment box.
* Bug: In Katana::PreProcess::propagateCagedConstraints(), when
looking at all the slave components anchoreds on a RoutingPad,
if they do not have an AutoSegment lookup, skip them instead
of crashing.
* New: In cumulus/plugins.block.Block.placeMacro(), new method to
place a macro cell, partly delegating to the Macro block wrapper.
Must be called *after* both core and corona abutment boxes have
been set.
Adjust the macro block position so the METAL2 & METAL3 pins
are exactly on pitch regarding the full routing grid. The reference
being the corona.
A shift, less than one pitch may be applied, leading in some
cases of overlapping abutment boxes. But this shouldn't be a
problem.
The macro to place is designated through a path of instances
names, rooted at the *core* (not the corona). Meaning that the
head instance must be one of the core.
* Change: In cumulus/plugins.chip.Chip, the complete chip I/O pads
plus corona and core placement is moved out from doPnR() and
put into doChipFloorplan(). It is now mandatory to call this
method *before* doPnR().
Those methods are now cleanly separated so we can perform macro
block placement or any inner core floorplaning operations between
them.
* Change: In cumulus/plugins.macro.Macro, instead of creating large
pads for the I/O pins so whatever the block position, they will
be under a grid point, create a simple dogleg to put them on
grid.
To ensure that they are "on grid", the block pins must be
in METAL2 (horizontal E/W) or METAL3 (vertical N/S) and the block
is assumed to be placed so the bottom left corner of it's
abutment box is exactly on one grid point for M2/M3.
This should be done by Block.placeMacro().

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
