Release Notes
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
Release 1.0.1475
|
|
|
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
This is the first preliminary release of the |Coriolis2| framework.
|
|
|
|
|
|
|
|
|
|
This release mainly ships the global router |Knik| and the detailed router
|
|
|
|
|
|Kite|. Together they aim to replace the |Alliance| |Nero| router.
|
|
|
|
|
Unlike |Nero|, |Kite| is based on an innovating routing modeling and ad-hoc
|
|
|
|
|
algorithm. Although it is released under |GPL| license, the source code
|
|
|
|
|
will be avalaible later.

|
|
|
|
|
|
|
|
|
|
1. A graphical user interface (viewer only).
|
|
|
|
|
2. The |Knik| global router.
|
|
|
|
|
3. The |Kite| detailed router.
|
|
|
|
|
|
|
|
|
|
|noindent| Supported input/output formats:
|
|
|
|
|
|
|
|
|
|
* |Alliance| |vst| (netlist) & |ap| (physical) formats.
|
|
|
|
|
* Even if there are some references to the |Cadence| |LEFDEF| format, its
|
|
|
|
|
support is not included because it depends on a library only available
|
|
|
|
|
to |Si2| affiliated members.

2015-02-27 11:16:03 -06:00
|
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
#. Replace the old simulated annealing placer |Mauka| by an analytic placer
|
|
|
|
|
|Etesian|.
|
|
|
|
|
#. The multiples user defined configuration files are now grouped under
|
|
|
|
|
a common hidden (dot) directory ``.coriolis2`` and the file extension
|
|
|
|
|
is back from ``.conf`` to ``.py``.
|
|
|
|
|
#. Under |RHEL7| / |SL7|, there is a known bug in the graphical visualizer.
|
|
|
|
|
When shifting to the left, the right-half part of the screen gets
|
|
|
|
|
badly redrawn. Uses |CTRL_L| to refresh. It will be corrected as soon
|
|
|
|
|
as possible.

|
|
|
.. note::
|
|
|
|
|
As the sources are being released, the binary packaging is dropped.
|
|
|
|
|
You still may find older version here: http://asim.lip6.fr/pub/coriolis/2.0 .
|
|
|
|
|
|
|
|
|
|
In a nutshell, building source consist in pulling the |git| repository then
|
|
|
|
|
running the |ccb| installer.
|
|
|
|
|
|
|
|
|
|

Fixed Directory Tree
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
In order to simplificate the work of the |ccb| installer, the source, build
|
|
|
|
|
and installation tree is fixed. To successfully compile |Coriolis| you must
|
|
|
|
|
follow it exactly. The tree is relative to the home directory of the user
|
|
|
|
|
building it (noted :fboxtt:`~/` or :fboxtt:`$HOME/`). Only the source
|
|
|
|
|
directory needs to be manually created by the user, all others will be
|
|
|
|
|
automatically created either by |ccb| or the build system.

.. note:: *Alternate build types:* the ``Release.Shared`` means an optimized build
|
|
|
|
|
with shared libraries. But there are also available ``Static`` instead of ``Shared``
|
|
|
|
|
and ``Debug`` instead of ``Release`` and any combination of them.
|
|
|
|
|
|
|
|
|
|
``Static`` do not work because I don't know yet to mix statically linked binaries
|
|
|
|
|
and Python modules (which must be dynamic).

Building Coriolis
|
|
|
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The first step is to create the source directory and pull the |git| repository: ::
|
|
|
|
|
|
|
|
|
|
dummy@lepka:~$ mkdir -p ~/coriolis-2.x/src
|
|
|
|
|
dummy@lepka:~$ cd ~/coriolis-2.x/src
|
|
|
|
|
dummy@lepka:~$ git clone https://www-soc.lip6.fr/git/coriolis.git
|
2015-02-27 11:16:03 -06:00
|
|
|
dummy@lepka:~$ mkdir importeds
|
|
|
|
|
dummy@lepka:~$ cd importeds
|
|
|
|
|
dummy@lepka:~$ git clone https://github.com/Coloquinte/Coloquinte.git
|
|
|
|
|
dummy@lepka:~$ cd ../coriolis
|
2014-03-10 08:06:31 -05:00
|
|
|
|
|
|
|
|
Second and final step, build & install: ::
|
|
|
|
|
|
2015-03-06 01:58:10 -06:00
|
|
|
dummy@lepka:src$ ./bootstrap/ccp.py --project=importeds \
|
|
|
|
|
--project=coriolis \
|
2015-02-27 11:16:03 -06:00
|
|
|
--make="-j4 install"
|
2015-03-06 01:58:10 -06:00
|
|
|
dummy@lepka:src$ ./bootstrap/ccb.py --project=coriolis \
|
|
|
|
|
--doc --make="-j1 install"
|
2014-03-10 08:06:31 -05:00
|
|
|
|
|
|
|
|
We need two steps because the documentation do not support to be generated with
|
|
|
|
|
a parallel build. So we compile & install in a first step in ``-j4`` (or whatever)
|
|
|
|
|
then we generate the documentation in ``-j1``
|
|
|
|
|
|
2015-02-27 11:16:03 -06:00
|
|
|
Under |RHEL6| or clones, you must build using the |devtoolset2|: ::
|
|
|
|
|
|
2015-03-06 01:58:10 -06:00
|
|
|
dummy@lepka:src$ ./bootstrap/ccp.py --project=importeds \
|
|
|
|
|
--project=coriolis \
|
2015-02-27 11:16:03 -06:00
|
|
|
--devtoolset-2 --make="-j4 install"
|
|
|
|
|
|
|
|
|
|
If you want to uses Qt 5 instead of Qt 4, you may add the ``--qt5`` argument.
|
|
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
The complete list of |ccb| functionalities can be accessed with the ``--help`` argument.
|
|
|
|
|
It also may be run in graphical mode (``--gui``).
|
|
|
|
|
|
|

|
|
Building the Devel Branch
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
In the |Coriolis| |git| repository, two branches are present:
|
|
|
|
|
|
|
|
|
|
* The :cb:`master` branch, which contains the latest stable version. This is the
|
|
|
|
|
one used by default if you follow the above instructions.
|
|
|
|
|
|
|
|
|
|
* The :cb:`devel` branch, which obviously contains the latest commits from the
|
|
|
|
|
development team. To use it instead of the :cb:`master` one, do the following
|
|
|
|
|
command just after the first step: ::
|
|
|
|
|
|
|
|
|
|
dummy@lepka:~$ git checkout devel
|
2015-03-06 01:58:10 -06:00
|
|
|
dummy@lepka:src$ ./bootstrap/ccp.py --project=importeds \
|
|
|
|
|
--project=coriolis \
|
2015-02-27 11:16:03 -06:00
|
|
|
--make="-j4 install" --debug
|
2014-07-13 06:14:49 -05:00
|
|
|
|
2014-12-12 05:05:25 -06:00
|
|
|
Be aware that it may requires newer versions of the dependencies and may introduce
|
2014-07-13 06:14:49 -05:00
|
|
|
incompatibilites with the stable version.
|
|
|
|
|
|
2015-02-27 11:16:03 -06:00
|
|
|
In the (unlikely) event of a crash of |cgt|, as it is a |Python| script, the right
|
|
|
|
|
command to run |gdb| on it is: ::
|
2014-12-12 05:05:25 -06:00
|
|
|
|
2015-02-27 11:16:03 -06:00
|
|
|
dummy@lepka:work$ gdb python core.XXXX
|
2014-12-12 05:05:25 -06:00

Additionnal Requirement under |MacOS|
|
|
|
|
|
-------------------------------------
|
|
|
|
|
|
|
|
|
|
|Coriolis| make uses of the :cb:`boost::python` module, but the |macports| |boost|
|
|
|
|
|
seems unable to work with the |Python| bundled with |MacOS|. So you have to install
|
|
|
|
|
both of them from |macports|: ::
|
|
|
|
|
|
|
|
|
|
dummy@macos:~$ port install boost +python27
|
|
|
|
|
dummy@macos:~$ port select python python27
|
2014-12-12 05:05:25 -06:00
|
|
|
dummy@macos:-$ export DYLD_FRAMEWORK_PATH=/opt/local/Library/Frameworks
|
|
|
|
|
|
|
|
|
|
The last two lines tell |MacOS| to use the |Python| from |macports| and *not* from
|
|
|
|
|
the system.
|
2014-05-13 10:15:29 -05:00
|
|
|
|
|
|
|
|
Then proceed with the generic install instructions.

Packaging Coriolis
|
|
|
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Packager should not uses |ccb|, instead ``bootstrap/Makefile.package`` is provided
|
|
|
|
|
to emulate a top-level ``autotool`` makefile. Just copy it in the root of the
|
|
|
|
|
|Coriolis| git repository (``~/corriolis-2.x/src/coriolis/``) and build.
|
2012-11-16 06:49:47 -06:00
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
Sligthly outaded packaging configuration files can also be found under ``bootstrap/``:
|
2012-11-16 06:49:47 -06:00
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
* ``bootstrap/coriolis2.spec.in`` for |rpm| based distributions.
|
|
|
|
|
* ``bootstrap/debian`` for |Debian| based distributions.

Hooking up into |Alliance|
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
|Coriolis| relies on |Alliance| for the cell libraries. So after installing or
|
|
|
|
|
packaging, you must configure it so that it can found those libraries.
|
|
|
|
|
|
|
|
|
|
This is done by editing the one variable :cb:`cellsTop` in the |Alliance| helper
|
|
|
|
|
(see `Alliance Helper`_). This variable must point to the directory of the
|
|
|
|
|
cells libraries. In a typical installation, this is generally
|
|
|
|
|
:cb:`/usr/share/alliance/cells`.
|
|
|
|

Setting up the Environment (coriolisEnv.py)
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
2014-03-10 08:06:31 -05:00
|
|
|
|
|
|
|
|
To simplify the tedious task of configuring your environment, a helper is provided
|
2014-12-12 05:05:25 -06:00
|
|
|
in the ``bootstrap`` source directory (also installed in the directory
|
|
|
|
|
``.../install/etc/coriolis2/``) : ::
|
2014-03-10 08:06:31 -05:00
|
|
|
|
2014-12-12 05:05:25 -06:00
|
|
|
~/coriolis-2.x/src/coriolis/bootstrap/coriolisEnv.py
|
2014-03-10 08:06:31 -05:00
|
|
|
|
|
|
|
|
Use it like this: ::
|
|
|
|
|
|
2014-12-12 05:05:25 -06:00
|
|
|
dummy@lepka:~> eval `~/coriolis-2.x/src/coriolis/bootstrap/coriolisEnv.py`
|
|
|
|
|
|
|
|
|
|
.. note:: **Do not call that script in your environement initialisation.**
|
|
|
|
|
When used under |RHEL6| or clones, it needs to be run in the |devtoolset2|
|
|
|
|
|
environement. The script then launch a new shell, which may cause an
|
|
|
|
|
infinite loop if it's called again in, say :cb:`~/.bashrc`.
|
|
|
|
|
|
|
|
|
|
Instead you may want to create an alias: ::
|
|
|
|
|
|
|
|
|
|
alias c2r='eval "`~/coriolis-2.x/src/coriolis/bootstrap/coriolisEnv.py`"'

Documentation
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
The general index of the documentation for the various parts of Coriolis
|
2014-03-10 08:06:31 -05:00
|
|
|
are avalaibles here `Coriolis Tools Documentation`_.
|
|
|
|
|
|
|
|
|
|
.. note:: **Python Documentation:**
|
|
|
|
|
Most of the documentation is related to the C++ API and implemetation of
|
|
|
|
|
the tools. However, the |Python| bindings have been created so they
|
|
|
|
|
mimic *as closely as possible* the C++ interface, so the documentation
|
|
|
|
|
applies to both languages with only minor syntactic changes.
|
|
|
|
|
|
Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.

General Software Architecture
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
2014-03-10 08:06:31 -05:00
|
|
|
|
|
|
|
|
|Coriolis| has been build with respect of the classical paradigm that the
|
|
|
|
|
computational instensive parts have been written in C++, and almost
|
|
|
|
|
everything else in |Python|. To build the |Python| interface we used
|
|
|
|
|
two methods:
|
|
|
|
|
|
|
|
|
|
* For self-contained modules :cb:`boost::python` (mainly in :cb:`vlsisapd`).
|
|
|
|
|
* For all modules based on |Hurricane|, we created our own wrappers due
|
|
|
|
|
to very specific requirements such as shared functions between modules
|
|
|
|
|
or C++/|Python| secure bi-directional object deletion.

Coriolis Configuration & Initialisation
|
|
|
|
|
=======================================
|
|
|
|
|
|
|
|
|
|
All configuration & initialization files are Python scripts, despite their
|
|
|
|
|
|dot_conf| extention. From a syntactic point of view, there is no difference
|
|
|
|
|
between the system-wide configuration files and the user's configuration,
|
|
|
|
|
they may use the same Python helpers.
|
|
|
|
|
|medskip|
|
|
|
|
|
|
2014-05-21 17:13:17 -05:00
|
|
|
Configuration is done in two stages:
|
|
|
|
|
|
|
|
|
|
#. Selecting the symbolic technology.
|
|
|
|
|
#. Loading the complete configuration for the given technology.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
First Stage: Symbolic Technology Selection
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
2012-11-16 06:49:47 -06:00
|
|
|
|noindent|
|
|
|
|
|
The initialization process is done by executing, in order, the following
|
|
|
|
|
file(s):
|
|
|
|
|
|
|
|
|
|

|
|
| **1** | The system setting | :cb:`/etc/coriolis2/techno.conf` |

|
|
|
|
|
|
|
|
|
|
Thoses files must provides only two variables, the name of the symbolic technology
|
|
|
|
|
and the one of the real technology. For example: ::
|
|
|
|
|
|
|
|
|
|
# -*- Mode:Python -*-
|
|
|
|
|
|
|
|
|
|
symbolicTechno = 'cmos'
|
|
|
|
|
realTechno = 'hcmos9'
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Second Stage: Technology Configuration Loading
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
|noindent|
|
|
|
|
|
The :cb:`TECHNO` variable is set by the first stage and it's the name of the
|
|
|
|
|
symbolic technology. A directory of that name, with all the configuration files,
|
|
|
|
|
must exists in the configuration directory. In addition to the technology-specific
|
|
|
|
|
directories, a :cb:`common/` directory is there to provides a trunk for all the
|
|
|
|
|
identical datas across the various technologies. The initialization process is done
|
|
|
|
|
by executing, in order, the following file(s):

|
|
.. note:: *The loading policy is not hard-coded.* It is implemented
|
2015-02-27 11:16:03 -06:00
|
|
|
at Python level in :cb:`/etc/coriolis2/coriolisInit.py`, and thus may be easily be
|
2012-11-16 06:49:47 -06:00
|
|
|
amended to whatever site policy.
|
|
|
|
|
|
|
|
|
|
The truly mandatory requirement is the existence of :cb:`coriolisInit.py`
|
|
|
|
|
which *must* contain a :cb:`coriolisConfigure()` function with no argument.
|
|
|
|

Configuration Helpers
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
To ease the writing of configuration files, a set of small helpers
|
|
|
|
|
is available. They allow to setup the configuration parameters through
|
2014-03-10 08:06:31 -05:00
|
|
|
simple assembly of tuples. The helpers are installed under the directory: ::
|
|
|
|
|
|
|
|
|
|
<install>/etc/coriolis2/
|
2012-11-16 06:49:47 -06:00
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
Where :cb:`<install>/` is the root of the installation.

|noindent| The example above shows the system configuration file, with all the
|
|
|
|
|
available settings. Some important remarks about thoses settings:
|
|
|
|
|
|
|
|
|
|
* 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 ``SYSTEM_LIBRARY``,
|
|
|
|
|
the ``WORKING_LIBRARY`` and the special net names (at this point there is not
|
|
|
|
|
much alternatives for the others settings).
|
|
|
|
|
|
|
|
|
|
* ``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:
|
|
|
|
|
|
|
|
|
|
* :cb:`Environment::Append`: append to the search path.
|
|
|
|
|
|
|
|
|
|
* :cb:`Environment::Prepend`: insert in head of the search path.
|
|
|
|
|
|
|
|
|
|
* :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.
|
|
|
|
|
|
|
|
|
|
A library is identified by it's name, this name is the last component of the
|
|
|
|
|
path name. For instance: ``/soc/alliance/sxlib`` will be named ``sxlib``.
|
|
|
|
|
Implementing the |Alliance| specification, when looking for a |Cell| ``name``,
|
|
|
|
|
the system will browse sequentially trought the library list and returns
|
|
|
|
|
the first |Cell| whose name match.
|
|
|
|
|
|
|
|
|
|
* For ``POWER``, ``GROUND``, ``CLOCK`` and ``BLOCKAGE`` net names, a regular
|
|
|
|
|
expression (|GNU| regexp) is expected.
|
|
|
|
|
|
|
|
|
|
* The ``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: ``/soc/coriolis2``.

|
.. * Trick and naming convention about ``SYMBOLIC_TECHNOLOGY``, ``REAL_TECHNOLOGY``
|
|
|
|
|
.. and ``DISPLAY``. In the previous releases, thoses files where to read by
|
|
|
|
|
.. XML parsers, and still do if you triggers the XML compatibility mode.
|
|
|
|
|
.. But now, they have Python conterparts. In the configuration files, you
|
|
|
|
|
.. still have to name them as XML files, the Python file name will be
|
|
|
|
|
.. deduced from this one with thoses two translation rules:
|
|
|
|
|
..
|
|
|
|
|
.. #. In the filename, all dots, except for the last (the file extention),
|
|
|
|
|
.. are replaced by underscores.
|
|
|
|
|
..
|
|
|
|
|
.. #. The ``.xml`` extention is substituted by a ``.conf``.
|
|
|
|
|
..
|
|
|
|
|
.. For the symbolic technology, it would give: ::
|
|
|
|
|
..
|
|
|
|
|
.. /soc/coriolis2/technology.symbolic.xml
|
|
|
|
|
.. --> /soc/coriolis2/technology_symbolic.conf
|
2012-11-16 06:49:47 -06:00
|
|
|
|
|
|
|
|
A typical user's configuration file would be: ::
|
|
|
|
|
|
|
|
|
|
import os
|
|
|
|
|
|
|
|
|

Tools Configuration Helpers
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
All the tools uses the same helper to load their configuration (a.k.a.
|
|
|
|
|
*Configuration Helper*). Currently the following configuration system-wide
|
|
|
|
|
configuration files are defined:
|
|
|
|
|
|
|
|
|
|
* :cb:`misc.conf`: commons settings or not belonging specifically to a tool.
|
2015-02-27 11:16:03 -06:00
|
|
|
* :cb:`etesian.conf`: for the |Etesian| tool.

Taxonomy of the file:
|
|
|
|
|
|
|
|
|
|
* It must contains, at least, the two tables:
|
|
|
|
|
|
|
|
|
|
* ``parametersTable``, defines & initialise the configuration variables.
|
|
|
|
|
|
|
|
|
|
* ``layoutTables``, defines how the various parameters will be displayed
|
2014-03-10 08:06:31 -05:00
|
|
|
in the configuration window (`The Settings Tab`_).
|
2012-11-16 06:49:47 -06:00
|
|
|
|
|
|
|
|
* The ``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
|
|
|
|
|
:cb:`(TypeOption, 'paramId', ParameterType, DefaultValue)` with:
|
|
|
|
|
|
|
|
|
|
#. ``TypeOption``, tells that this tuple describe a parameter.
|
|
|
|
|
|
|
|
|
|
#. ``paramId``, the identifier of the parameter. Identifiers are defined
|
|
|
|
|
by the tools. The list of parameters is detailed in each tool section.
|
|
|
|
|
|
|
|
|
|
#. ``ParameterType``, the kind of parameter. Could be:
|
|
|
|
|
|
|
|
|
|
* ``TypeBool``, boolean.
|
|
|
|
|
* ``TypeInt``, signed integer.
|
|
|
|
|
* ``TypeEnumerate``, enumerated type, needs extra entry.
|
|
|
|
|
* ``TypePercentage``, percentage, expressed between 0 and 100.
|
|
|
|
|
* ``TypeDouble``, float.
|
|
|
|
|
* ``TypeString``, character string.
|
|
|
|
|
|
|
|
|
|
#. ``DefaultValue``, the default value for that parameter.

Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.

|
2015-02-27 11:16:03 -06:00

CGT - The Graphical Interface
|
|
|
|
|
=============================
|
|
|
|
|
|
|
|
|
|
The |Coriolis| graphical interface is split up into two windows.
|
|
|
|
|
|
|
|
|
|
* The **Viewer**, with the following features:
|
|
|
|
|
|
|
|
|
|
* Basic load/save capabilities.
|
|
|
|
|
* Display the current working cell. Could be empty if the design
|
|
|
|
|
is not yet placed.
|
|
|
|
|
* Execute Stratus Scripts.
|
|
|
|
|
* Menu to run the tools (placement, routage).
|
|
|
|
|
|
|
|
|
|
Features are detailed in `Viewer & Tools`_.
|
|
|
|
|
|
|
|
|
|
|ViewerSnapShot_1|
|
|
|
|
|
|
|
|
|
|
* The **Controller**, which allows:
|
|
|
|
|
|
|
|
|
|
* Tweak what is displayer by the *Viewer*. Through the *Look*,
|
|
|
|
|
*Filter* and *Layers&Gos* tabs.
|
|
|
|
|
* Browse the |netlist| with eponym tab.
|
|
|
|
|
* Show the list of selected objects (if any) with *selection*
|
|
|
|
|
* Walk through the Database, the Cell or the Selection with *Inspector*.
|
|
|
|
|
This is an advanced feature, reserved for experimented users.
|
|
|
|
|
* The tab *Settings* which give access to all the settings.
|
|
|
|
|
They are closely related to Configuration & Initialisation.

|Stratus| Netlist Capture
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
|Stratus| is the replacement for |GenLib| procedural netlist capture language.
|
|
|
|
|
It is designed as a set of |Python| classes, and comes with it's own documentation
|
|
|
|
|
(`Stratus Documentation`_)
|
|
|
|
|
|
|
|
|
|
|
2012-11-16 06:49:47 -06:00
|
|
|
The |Hurricane| Data-Base
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The |Alliance| flow is based on the |MBK| data-base, which has one data-structure
|
|
|
|
|
for each view. That is, |LOFIG| for the *logical* view and |PHFIG| for the *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 *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 has 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 use the |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 |Coriolis|.
|
|
|
|
|
|
2015-04-05 04:35:06 -05:00
|
|
|
As for the second release, |Coriolis| can be used only for three purposes :
|
2012-11-16 06:49:47 -06:00
|
|
|
|
2015-04-05 04:35:06 -05:00
|
|
|
* **Placing a design**, in which case the |netlist| view must be present.
|
2012-11-16 06:49:47 -06:00
|
|
|
* **Routing a design**, in that case the |netlist|
|
|
|
|
|
view and the |layout| view must be present and |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 |layout| view will be overwritten.
|
|
|
|
|
* **Viewing a design**, the |netlist| view must be present, if a |layout|
|
|
|
|
|
view is present it still must have the same name but it can be in any
|
|
|
|
|
state.

Synthetizing and loading a design
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
|Coriolis| supports several file formats. It can load all file format
|
|
|
|
|
from the |Alliance| toolchain (.ap for layout, behavioural and structural vhdl .vbe and .vst),
|
|
|
|
|
BLIF netlist format as well as benchmark formats from the ISPD contests.
|
|
|
|
|
|
|
|
|
|
It can be compiled with LEF/DEF support, although it requires acceptance of the SI2 license
|
|
|
|
|
and may not be compiled in your version of the software.
|
|
|
|
|
|
|
|
|
|
Synthesis under Yosys
|
|
|
|
|
---------------------
|
|
|
|
|
|
|
|
|
|
You can create a BLIF file from the |Yosys| synthetizer, which can be imported under Coriolis.
|
|
|
|
|
Most libraries are specified as a .lib liberty file and a .lef LEF file. Although |Yosys| opens
|
|
|
|
|
most .lib files with minor modifications, Coriolis may be compiled without LEF support, in
|
|
|
|
|
which case you need .ap files.
|
|
|
|
|
In this case, you need to export your .lef library as .ap files or compile your Coriolis version
|
|
|
|
|
with LEF support.
|
|
|
|
|
|
|
|
|
|
Once you have installed a common library under |Yosys| and Coriolis, just synthetize your design
|
|
|
|
|
with |Yosys| and import it (as Blif without the extension) under Coriolis to perform place&route.
|
|
|
|
|
|
|
|
|
|
Synthesis under Alliance
|
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
|
|
|Alliance| is an older toolchain but has been extensively used for years. Coriolis can import
|
|
|
|
|
and write Alliance designs and libraries directly.
|
|
|
|

Etesian -- Placer
|
|
|
|
|
~~~~~~~~~~~~~~~~~
|
2012-11-16 06:49:47 -06:00
|
|
|
|
2015-04-05 04:35:06 -05:00
|
|
|
The |Etesian| placer is a state of the art (as of 2015) analytical placer. It is
|
|
|
|
|
within ``5%`` of other placers' solutions, but is normally a bit worse than ePlace.
|
|
|
|
|
This |Coriolis| tool is actually an encapsulation of |Coloquinte| which *is* the placer.
|
|
|
|
|
|Coloquinte| is provided as a separate library, see the building instructions.

**Hierarchical Placement**
|
|
|
|
|
|
|
|
|
|
The placement area is defined by the top cell abutment box.
|
|
|
|
|
|
|
|
|
|
When placing a complete hierarchy, the abutment boxes of the cells (models) other than
|
|
|
|
|
the top cell are sets identical to the one of the top cell and their instances are
|
|
|
|
|
all placed at position ``(0,0,ID)``. That is, all the abutments boxes, whatever the
|
|
|
|
|
hierarchical level, defines the same area (they are exactly superposed).
|
|
|
|
|
|
|
|
|
|
We choose this scheme because the placer will see all the instances as virtually
|
|
|
|
|
flattened, so they can be placed anywhere inside the top-cell abutment box.

|
|
|
|
|
**Computing the Placement Area**
|
|
|
|
|
|
|
|
|
|
The placement area is computed using the ``etesian.aspectRatio`` and ``etesian.spaceMargin``
|
|
|
|
|
parameters only if the top-cell has an empty abutment box. If the top-cell abutment
|
|
|
|
|
box has to be set, then it is propagated to all the instances models recursively.

|
|
|
**Reseting the Placement**
|
|
|
|
|
|
|
|
|
|
Once a placement has been done, the placer cannot reset it (will be implemented
|
|
|
|
|
later). To perform a new placement, you must restart |cgt|. In addition, if you
|
|
|
|
|
have saved the placement on disk, you must erase any :cb:`.ap` file, which are
|
|
|
|
|
automatically reloaded along with the netlist (:cb:`.vst`).

|
|
**Limitations**
|
|
|
|
|
|
|
|
|
|
Etesian supports standard cells and fixed macros. As for the Coriolis 2.1 version,
|
|
|
|
|
it doesn't support movable macros, and you must place every macro beforehand.
|
|
|
|
|
Timing and routability analysis are not included either, and the returned placement
|
|
|
|
|
may be unroutable.

Knik -- Global Router

The quality of |Knik| global routing solutions are equivalent to those of FGR_ 1.0.
|
|
|
|
|
For an in-depth description of |Knik| algorithms, you may download the thesis of
|
|

|
D. |Dupuis| avalaible from here~: `Knik Thesis`_.

The global router is (not yet) deterministic. To circumvent this limitation,
|
2014-03-10 08:06:31 -05:00
|
|
|
a global routing *solution* can be saved to disk and reloaded for later uses.
|
2012-11-16 06:49:47 -06:00

|
|
|
|

A global routing is saved into a file with the same name as the design and a
|
|
|
|
|
|kgr| extention. It is in `Box Router`_ output format.

Kite -- Detailed Router
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
|Kite| no longer suffers from the limitations of |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 `150K` gates.
|

|
|
|
|noindent| However, this first release comes with the temporary the following
|
|
|
|
|
restrictions:
|
2012-11-16 06:49:47 -06:00
|
|
|
|
|
|
|
|
* Works only with |SxLib| standard cell gauge.
|
|
|
|
|
* Works always with 4 routing metal layers (`M2` through `M5`).
|
|
|
|
|
* Do not allow (take into account) pre-routed wires on signals
|
|
|
|
|
other than |POWER| or |GROUND|.
|
|
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
.. note::
|
|
|
|
|
**Slow Layer Assignment.** Most of the time, the layer assignment stage is
|
|
|
|
|
fast (less than a dozen seconds), but in some instances it can take more
|
|
|
|
|
than a dozen *minutes*. This is a known bug and will be corrected in later
|
|
|
|
|
releases.
|
|
|
|
|
|
2012-11-16 06:49:47 -06:00
|
|
|
After each run, |Kite| displays a set of *completion ratios* which must all
|
|
|
|
|
be equal to `100%` if the detailed routing has been successfull.
|
2014-03-10 08:06:31 -05:00
|
|
|
In the event of a failure, on a saturated design, you may decrease the
|
|
|
|
|
`edge saturation ratio` (argument `--edge`) to balance more evenly the design
|
2012-11-16 06:49:47 -06:00
|
|
|
saturation. That is, the maximum saturation decrease at the price of a wider
|
2014-03-10 08:06:31 -05:00
|
|
|
saturated area and increased wirelength. This is the saturation of the
|
|
|
|
|
*global* router |Knik|, and you may increase/decrease by steps of ``5%``,
|
|
|
|
|
which represent one track. The maximum capacity of the |SxLib| gauge is
|
|
|
|
|
10 tracks in two layers, that makes 20 tracks by |Knik| edge.
|
2012-11-16 06:49:47 -06:00
|
|
|
|
Add NetRoutingState (Property) on Nets to tell Kite what to do.
* New: In Katabatic, add the ability to decorate some (i.e. few) nets
with a state that indicate to Katabatic & Kite what to do with it.
The possible states are:
1. Fixed : all the wire are in fixed positions. The router cannot
move them and account them as obstacles.
2. ManualGlobalRoute : a user-defined topology is supplied. The
wires still have to be detailed route in "Detailed Pre-Route"
but will be skipped for the global routing and fixed for the
general Detailed route.
3. AutomaticGlobalRoute : ordinary nets, to be global routed then
detail routed.
4. Excluded : do not try to global or detail route thoses nets.
5. MixedPreRoute : mask combining Fixed and ManualGlobalRoute.
Not all nets have this property, only those that needs a special
processing.
To ease the access to the state, it is nested inside a
PrivateProperty in the net (NetRoutingProperty), with an extension
access class (NetRoutingExtension).
* New: In Kite, take account of NetRoutingState. Pointers to the
net's states are strored inside an internal map for faster access.
The property is *not* deleted when Kite is destroyed. The property
will remains until the Net itself is destroyed.
As a consequence, the lists that where passed to high level
function are removed as the information can now be accessed directly
through the net NetRoutingProperty.
* New: In Unicorn, in CgtMain, comply with the update interface.
* New: In documentation, update the User's Guide to explain the Pre-routed
step of Kite.

Routing a design is done in four ordered steps:
|
|
|
|
|
|
|
|
|
|
#. Detailed pre-route |menu_P&R| |rightarrow| |menu_StepByStep| |rightarrow| |menu_KiteDetailedPreRoute|.
|
|
|
|
|
#. Global routing |menu_P&R| |rightarrow| |menu_StepByStep| |rightarrow| |menu_KiteGlobalRoute|.
|
|
|
|
|
#. Detailed routing |menu_P&R| |rightarrow| |menu_StepByStep| |rightarrow| |menu_KiteDetailedRoute|.
|
|
|
|
|
#. Finalize routing |menu_P&R| |rightarrow| |menu_StepByStep| |rightarrow| |menu_KiteFinalizeRoute|.
|
|
|
|
|

|
|
|
|
It is possible to supply to the router a complete wiring for some nets that the user's
|
|
|
|
|
wants to be routed according to a specific topology. The supplied topology must respect
|
|
|
|
|
the building rules of the |Katabatic| database (contacts must be, terminals, turns, h-tee
|
|
|
|
|
& v-tee only). During the first step :fboxtt:`Detailed Pre-Route` the router will solve
|
|
|
|
|
overlaps between the segments, without making any dogleg. If no pre-routed topologies
|
|
|
|
|
are present, this step may be ommited. Any net routed at this step is then fixed and
|
|
|
|
|
become unmovable for the later stages.
|
|
|
|
|
|
|
|
|
|
After the detailed routing step the |Kite| data-structure is still active
|
|
|
|
|
(the Hurricane wiring is decorated). The finalize step performs the removal of
|
|
|
|
|
the |Kite| data-structure, and it is not advisable to save the design before
|
|
|
|
|
that step.

You may visualize the density (saturation) of either |Knik| (on edges) or
|
|
|
|
|
|Kite| (on GCells) until the routing is finalized. Special layers appears

|

to that effect in the `The Layers&Go Tab`_.

Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.

Executing Python Scripts in Cgt
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Python/Stratus scripts can be executed either in text or graphical mode.
|
|
|
|
|
|
2014-03-10 08:06:31 -05:00
|
|
|
.. note:: **How Cgt Locates Python Scripts:**
|
2012-11-16 06:49:47 -06:00
|
|
|
|cgt| uses the Python ``import`` mechanism to load Python scripts.
|
|
|
|
|
So you must give the name of your script whitout ``.py`` extention and
|
|
|
|
|
it must be reachable through the ``PYTHONPATH``. You may uses the
|
|
|
|
|
dotted module notation.
|
|
|
|
|
|
Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.
2014-06-28 10:37:59 -05:00

|
A Python/Stratus script must contains a function called ``ScriptMain()``

with one optional argument, the graphical editor into which it may be

Printing & Snapshots
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Printing or saving into a |pdf| is fairly simple, just uses the **File -> Print**
|
2015-03-06 01:58:10 -06:00
|
|
|
menu or the |CTRL_P| shortcut to open the dialog box.
|
2012-11-16 06:49:47 -06:00
|
|
|
|
|
|
|
|
The print functionality uses exactly the same rendering mechanism as for the
|
|
|
|
|
screen, beeing almost *WYSIWYG*. Thus, to obtain the best results it is advisable
|
|
|
|
|
to select the ``Coriolis.Printer`` look (in the *Controller*), which uses a
|
|
|
|
|
white background and much suited for high resolutions ``32x32`` pixels patterns
|
|
|
|
|
|
|
|
|
|
There is also two mode of printing selectable through the *Controller*
|
|
|
|
|
**Settings -> Misc -> Printer/Snapshot Mode**:
|
|
|
|
|
|
|
|
|
|
=============== ================= =====================================================
|
|
|
|
|
Mode DPI (approx.) Intended Usage
|
|
|
|
|
--------------- ----------------- -----------------------------------------------------
|
|
|
|
|
**Cell Mode** 150 For single ``Cell`` printing or very small designs.
|
|
|
|
|
Patterns will be bigger and more readable.
|
|
|
|
|
**Design Mode** 300 For designs (mostly commposed of wires and cells
|
|
|
|
|
outlines).
|
|
|
|
|
=============== ================= =====================================================
|
|
|
|
|
|
|
|
|
|
.. note:: *The pdf file size*
|
|
|
|
|
Be aware that the generated |pdf| files are indeed only pixmaps.
|
|
|
|
|
So they can grew very large if you select paper format above ``A2``
|
|
|
|
|
or similar.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|noindent|
|
|
|
|
|
Saving into an image is subject to the same remarks as for |pdf|.

|
|
|
|
The Controller
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
The *Controller* window is composed of seven tabs:
|
|
|
|
|
|
|
|
|
|
#. `The Look Tab`_ to select the display style.
|
|
|
|
|
#. `The Filter Tab`_ the hierarchical levels to be displayed, the look of
|
|
|
|
|
rubbers and the dimension units.
|
|
|
|
|
#. `The Layers&Go Tab`_ to selectively hide/display layers.
|
|
|
|
|
#. `The Netlist Tab`_ to browse through the |netlist|. Works in association
|
|
|
|
|
with the *Selection* tab.
|
|
|
|
|
#. `The Selection Tab`_ allow to view all the currently selected elements.
|
|
|
|
|
#. `The Inspector Tab`_ browse through either the DataBase, the Cell or
|
|
|
|
|
the current selection.
|
|
|
|
|
#. `The Settings Tab`_ access all the tool's configuration settings.

|
|
The Look Tab
|
|
|
|
|
~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
You can select how the layout will be displayed. There is a special one
|
|
|
|
|
``Printer.Coriolis`` specifically designed for `Printing & Snapshots`_.
|
|
|
|
|
You should select it prior to calling the print or snapshot dialog boxes.

|
|
|
The Filter Tab
|
|
|
|
|
~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The filter tab let you select what hierarchical levels of your design will be
|
|
|
|
|
displayed. Hierarchy level are numbered top-down: the level 0 correspond to
|
|
|
|
|
the top-level cell, the level one to the instances of the top-level Cell and
|
|
|
|
|
so on.
|
|
|
|
|
|
|
|
|
|
There are also check boxes to enable/disable the processing of Terminal Cell,
|
|
|
|
|
Master Cells and Compnents. The processing of Terminal Cell (hierarchy leaf
|
|
|
|
|
cells) is disabled by default when you load a hierarchical design and enabled
|
|
|
|
|
when you load a single Cell.
|
|
|
|
|
|
|
|
|
|
You can choose what kind of form to give to the rubbers and the type of
|
|
|
|
|
unit used to display coordinates.
|
|
|
|
|
|
|
|
|
|
.. note:: *What are Rubbers:* |Hurricane| uses *Rubbers* to materialize
|
|
|
|
|
physical gaps in net topology. That is, if some wires are missing to
|
|
|
|
|
connect two or more parts of net, a *rubber* will be drawn between them
|
|
|
|
|
to signal the gap.
|
|
|
|
|
|
|
|
|
|
For example, after the detailed routing no *rubbers* should remains.
|
|
|
|
|
They have been made *very* visibles as big violet lines...

|
|
The Layers&Go Tab
|
|
|
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Control the individual display of all *layers* and *Gos*.
|
|
|
|
|
|
|
|
|
|
* *Layers* correspond to a true physical layer. From a |Hurricane| point of
|
|
|
|
|
view they are all the *BasicLayers* (could be matched to GDSII).
|
|
|
|
|
* *Gos* stands from *Graphical Objects*, they are drawings that have no
|
|
|
|
|
physical existence but are added by the various tools to display extra
|
|
|
|
|
information. One good exemple is the density map of the detailed router,
|
|
|
|
|
to easily locate congested areas.
|
|
|
|
|
|
|
|
|
|
For each layer/Go there are two check boxes:
|
|
|
|
|
|
|
|
|
|
* The normal one triggers the display.
|
|
|
|
|
* The red-outlined allows objects of that layer to be selectable or not.

|
|
The Netlist Tab
|
|
|
|
|
~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The *Netlist* tab shows the list of nets... By default the tab is not
|
|
|
|
|
*synched* with the displayed Cell. To see the nets you must check the
|
|
|
|
|
**Sync Netlist** checkbox. You can narrow the set of displayed nets by
|
|
|
|
|
using the filter pattern (supports regular expressions).
|
|
|
|
|
|
|
|
|
|
An very useful feature is to enable the **Sync Selection**, which will
|
|
|
|
|
automatically select all the components of the selected net(s). You can
|
|
|
|
|
select multiple nets. In the figure the net ``auxsc35`` is selected and
|
|
|
|
|
is highlited in the *Viewer*.

The Selection Tab
|
|
|
|

~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The *Selection* tab list all the components currently selecteds. They
|
|
|
|
|
can be filtered thanks to the filter pattern.
|
|
|
|
|
|
|
|
|
|
Used in conjunction with the *Netlist* **Sync Selection** you will all see
|
|
|
|
|
all the components part of *net*.
|
|
|
|
|
|
|
|
|
|
In this list, you can toggle individually the selection of component by
|
|
|
|
|
pressing the ``t`` key. When unselected in this way a component is not
|
|
|
|
|
removed from the the selection list but instead displayed in red italic.
|
|
|
|
|
To see where a component is you may make it blink by repeatedly press

The Inspector Tab
|
|
|
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
This tab is very useful, but mostly for |Coriolis| developpers. It allows
|
|
|
|
|
to browse through the live DataBase. The *Inspector* provide three entry points:
|
|
|
|
|
|
|
|
|
|
* **DataBase**: Starts from the whole |Hurricane| DataBase.
|
|
|
|
|
* **Cell**: Inspect the currently loaded Cell.
|
|
|
|
|
* **Selection**: Inspect the object currently highlited in the *Selection* tab.
|
|
|
|
|
|
|
|
|
|
Once an entry point has been activated, you may recursively expore all
|
|
|
|
|
it's fields using the right/left arrows.
|
|
|
|
|
|
|
|
|
|
.. note:: *Do not put your fingers in the socket:* when inspecting
|
2015-04-05 04:35:06 -05:00
|
|
|
anything, do not modify the DataBase. If any object under inspection
|
2012-11-16 06:49:47 -06:00
|
|
|
is deleted, you will crash the application...
|
|
|

Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.

Python Interface for |Hurricane| / |Coriolis|
|
|
|
|
|
=============================================
|
|
|
|
|
|
|
|
|
|
The (almost) complete interface of |Hurricane| is exported as a |Python| module
|
|
|
|
|
and some part of the other components of |Coriolis| (each one in a separate
|
|
|
|
|
module). The interface has been made to mirror as closely as possible the
|
|
|
|
|
C++ one, so the C++ doxygen documentation could be used to write code with
|
|
|
|
|
either languages.
|
|
|
|
|
|
|
|
|
|
`Summary of the C++ Documentation <file:../../../index.html>`_
|
|
|
|
|
|
|
|
|
|
A script could be run directly in text mode from the command line or through
|
|
|
|
|
the graphical interface (see `Python Scripts in Cgt`_).

Make the Python interface closely mirroring the C++ one.
* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN

Plugins
|
|
|
|
|
=======
|
|
|
|
|
|
|
|
|
|
Plugins are |Python| scripts specially crafted to integrate with |cgt|.
|
|
|
|
|
Their entry point is a :cb:`ScriptMain()` method as described in
|
|
|
|
|
`Python Interface to Coriolis`_. They can be called by user scripts
|
|
|
|
|
through this method.

Chip Placement
|
|
|
|
|
~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Automatically perform the placement of a complete chip. This plugin, as well
|
|
|
|
|
as the other P&R tools expect a specific top-level hierarchy for the design.
|
|
|
|
|
The top-level hierarchy must contains the instances of all the I/O pads and
|
|
|
|
|
**exactly one** instance of the chip's core model.
|
|
|
|
|
|
|
|
|
|
|ChipStructure-1|
|
|
|
|
|
|
|
|
|
|
The designer must provide a configuration file that define the rules for the
|
|
|
|
|
placement of the top-level hierarchy (that is, the pads and the core).
|
|
|
|
|
This file must be named after the chip's name, by appending ``_chip.py``
|
|
|
|
|
(obviously, it is a |Python| file). For instance if the chip netlist file
|
|
|
|
|
is called ``amd2901_crl.vst``, then the configuration file must be named
|
|
|
|
|
``amd2901_crl_chip.vst``.
|
|
|
|
|
|
|
|
|
|
Example of chip placement configuration file (for ``AM2901``): ::
|
|
|
|
|
|
|
|
|
|
chip = \
|
|
|
|
|
{ 'pads.south' : [ 'p_a3' , 'p_a2' , 'p_a1' , 'p_r0'
|
|
|

|
|
|
|
|
, 'pads.east' : [ 'p_zero' , 'p_i0' , 'p_i1' , 'p_i2'

|
|
|
|

|
|
|
|
|
, 'pads.west' : [ 'p_cin' , 'p_i4' , 'p_i5' , 'p_i3'
|
|
|
|
|
, 'p_ck' , 'p_d0' , 'p_d1' , 'p_d2'
|
|
|
|
|
, 'p_d3' , 'p_q0' , 'p_f3' ]
|
|
|
|
|
, 'core.size' : ( 1500, 1500 )
|
|
|
|
|
, 'chip.size' : ( 3000, 3000 )
|
|

|

If no clock tree is generated, then the clock rail is *not* created.
|
|
|
|
|
So even if the requested number of rails ``chip.block.rails.count`` is, say 5,
|
|
|
|
|
only four rails (2* ``power``, 2* ``ground``) will be generateds.

Clock Tree
|
|
|
|
|
~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Insert a clock tree into a block. The clock tree uses the H strategy.
|
|
|
|
|
The clock net is splitted into sub-nets, one for each branch of the
|
|
|
|
|
tree.
|
|
|
|
|
|
|
|
|
|
* On **chips** design, the sub-nets are createds in the model of the
|
|
|
|
|
core block (then trans-hierarchically flattened to be shown at
|
|
|
|
|
chip level).
|
|
|
|
|
* On **blocks**, the sub nets are created directly in the top block.
|
|
|
|
|
* The sub-nets are named according to a simple geometrical scheme.
|
|
|
|
|
A common prefix ``ck_htree``, then one postfix by level telling
|
|
|
|
|
on which quarter of plane the sub-clock is located:
|
|
|
|
|
|
|
|
|
|
#. ``_bl``: bottom left plane quarter.
|
|
|
|
|
#. ``_br``: bottom right plane quarter.
|
|
|
|
|
#. ``_tl``: top left plane quarter.
|
|
|
|
|
#. ``_tr``: top right plane quarter.
|
|
|
|
|
|
|
|
|
|
We can have ``ck_htree_bl``, ``ck_htree_bl_bl``, ``ch_htree_bl_tl`` and so on.
|
|
|
|
|
|
|
|
|
|
The clock tree plugin works in four steps:
|
|
|
|
|
|
|
|
|
|
#. Build the clock tree: creates the top-block abutment box, compute the
|
|
|
|
|
levels of H tree neededs and place the clock buffers.
|
|
|
|
|
#. Once the clock buffers are placed, calls the placer (|etesian|) to place
|
|
|
|
|
the ordinary standart cells, whithout disturbing clock H-tree buffers.
|
|
|
|
|
#. At this point we know the exact positions of all the DFFs, so we can
|
|
|
|
|
connect them to the nearest H-tree leaf clock signal.
|
|
|
|
|
#. Leaf clock signals that are not connecteds to any DFFs are removed.
|
|
|
|
|
|
|
|
|
|
Netlist reorganisation:
|
|
|
|
|
|
|
|
|
|
* Obviously the top block or chip core model netlist is modificated to
|
|
|
|
|
contains all the clock sub-nets. The interface is *not* changed.
|
|
|
|
|
* If the top block contains instances of other models *and* those models
|
|
|
|
|
contains DFFs that get re-connecteds to the clock sub-nets (from the
|
|
|
|
|
top level). Change both the model netlist and interface to propagate
|
|
|
|
|
the relevant clock sub-nets to the instanciated model. The new model
|
|
|
|
|
with the added clock signal is renamed with a ``_clocked`` suffix.
|
|
|
|
|
For example, the sub-block model ``ram.vst`` will become ``ram_clocked.vst``.
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
If you are to re-run the clock tree plugin on a netlist, be careful
|
|
|
|
|
to erase any previously generated ``_clocked`` file (both netlist and
|
|
|
|
|
layout: ``rm *.clocked.{ap,vst}``). And restart |cgt| to clear it's
|
|
|
|
|
memory cache.

To illustrate the capabilities of |Coriolis| tools and |Python| scripting, a small
|
|
|
|
|
example, derived from the |Alliance| :cb:`AM2901` is supplied.

|
|
This example contains only the synthetized netlists and the :cb:`doChip.py` script
|
|
|
|
|
which perform the whole P&R of the design.
|
|
|
|
|
|
|
|
|
|
You can generate the chip using one of the following method:
|
|
|
|
|
|
|
|
|
|
#. **Command line mode:** directly run the script: ::
|
|
|
|
|
|
|
|
|
|
dummy@lepka:AM2901$ ./doChip -V --cell=amd2901
|
|
|
|
|
|
|
|
|
|
#. **Graphic mode:** launch |cgt|, load chip netlist ``amd2901`` (the top cell)
|
|
|
|
|
then run the |Python| script :cb:`doChip.py`.
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
Between two consecutive run, be sure to erase the netlist/layout generateds: ::
|
|
|
|
|
|
|
|
|
|
dummy@lepka:AM2901$ rm *_clocked*.vst *.ap
|
