* New: In Hurricane::Entity, add an id counter limit and a memory size
limit. The two limits are checked only when a new Entity object is
created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
parameter to specify the name of the ground/power signals to be
created if they are missing in a Cell. For Alliance libraries it
would be "vss" & "vdd" (default values), but for real technologies,
it is often "gnd!" & "vdd!".
The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
the center of the GCells common side. Gcells under a segment are
found by using the edge that cover the segment axis. When we have
a "bend" GCell stack and the axis is wrong, they could be ommited.
This was causing deleted segments to be not removed from some
Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
reference contact, select the fixed or terminal one instead of
always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
segment going through an Edge is starting/ending in either source
or target GCell of the edge (active only when running in channel
mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
only if it is not ending in either source or target (channel mode
only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
segment which is ending in either source or target (we *have* to
access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
the Edge which is on the side that will get splitted by the cut.
It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
update horizontals or verticals only. We may require only a partial
update when resizing the GCell in only one direction.
This, again, related to the fact that we compute the GCells under
a segment thanks to it's axis position, so we need to be very careful
when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
Edges can have a zero capacity, but still be reachable if the net has
a terminal in either source or target. Look for this case and return
a distance of zero instead of "unreachable". This was causing the
global routing not to complete in channel mode.
For computing the edge distance, makes the vertical edges much more
long (10 times) than the horizontal ones as the vertical capacity is
very limited. Hard coded for now, should make it a parameter in the
future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
of edges with reserveCapacity for each terminal inside a GCell.
Both north and south edges are decreased as we a terminal will
block both north and south edges.
As a counterpart, the Edge capacity is not decreased when the
global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
do not expand the slack for horizontal segments in channel mode.
So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
layout.
* Change: In documentation/CMakeLists.txt, for add_custom_targets(),
add_dependencies() no longer allow to give files (only others
*target* in the sense of cmake). We must use the DEPENDS option
of add_custom_target().
* Change: In documentation/UsersGuide, it seems that docutils no longer
handle correctly '$' and/or '_' in verbatim in the LaTeX backend.
(i.e. they are *not* escaped, resulting in math mode errors).
Remove those characters as we can use others...
* Commit a snaphot of the current documentation.
* New: In documentation, reorganise all the various documents into one
Sphinx coherent one. The index also provide a link toward the
Doxygen generated doc (C++ APIs) and the venerable LaTeX2HTML ones
(for Stratus).
This will make easier all future extensions to the doc corpus.
The generated documentation is commited into Git so a new user
can use it directly after cloning the repository.
The HTML doc is truly generated by Sphinx, but the pdf one is
created rst2latex. The Sphinx pdf writer is buggy when a "tabular"
contain a multicol and a multirow in the same area of the table.
rst2latex handles it correctly.
We use a theme borrowed for Read The Doc (half of it).
It seems that some Javascripts are not working correctly,
namely the folding of the navigation sub-menus and the index
generation and search mode.
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
down the program (three times for Kite!). Create a macro cdebug_log
which calls cdebug *only* if the debug level is active.
* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* Change: In Hurricane, in JsonReader::HurricaneHandler, add RawNumber().
Don't know what kind of data it parses, so for now if it's called,
just issue a warning.
* Bug: In documentation, in UsersGuide, add dependencies on doc_HTML and
doc_LaTeX so they are rebuild if the source files changes.
Some modifications to work with our new installation of TeXLive 2014.
* New: In boostrap, in ccb.py, added support for the "support" project
which contains external dependencies. Currently contains only
RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
the libraries, but create and ordered list of Cell. Deepest cells
(leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
Catalog and their associated properties. Adjustment of the
AllianceLibrary creation policy.
* Change: coriolis2.spec.in, Makefile.package and Builder/ccb now support
RHEL6, RHEL7 & Fedora.
* Change: In Bootstrap, added a flag to activate compilation with
openmp.
* Change: In documentation UserGuide, under RHEL7 documents generated
with pdflatex tends to make evince core-dump while trying to print.
So use latex+dvipdfm instead. Images then needs to be pdf with an
auxiliary .bb file (the BoundingBox line extracted from the .eps).
* Change: In Bootstrap & ccb, the coloquinte project is renamed into
"importeds", it will be the home of all the externally
devellopped softwares that are needed to build Coriolis.
Add explicit support for Fedora ("Linux.fc") and uses
site-packages, as everybody else.
* New: In CRL Core, in etc/, adds the configuration files for Etesian.
* New: In Etesian, activate the Configuration object. Now uses it's
own configuration variables instead of borrowing those of
Nimbus & Mauka.
* Change: In Documentation, updated User's Guide to present Etesian
as the placer, instead of Mauka.
* Change: In Cumulus, slight change in ClokTreePlugin and ChipPlugin
to match the new Etesian/Python interface.
* New: In all to CMakeLists.txt, disable the warning about deprecated
WIN32 under cygwin.
* New: In boostrap, in ccb.py, coriolisEnv.py and builder/Configuration.py
add recognition in uname for the values returned under Windows/Cygwin.
* New: In Documenation, in UsersGuide.rst add some informations about
Cygwin and a section for the devel branch.
* 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.
* 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.
In CRL Core configuration files, "display.conf", "patterns.conf" and
"technology.conf" share most of their code. So that common part is put
into "common/" and sourced from the final configuration file.
Update the documentation according the the new initialization scheme.
Details:
* New: in <bootstrap>: add support for devtoolset-2 in ccb. Run the
cmake commands through 'scl', set shell environment variables
BOOST_INCLUDEDIR & BOOST_LIBRARYDIR and disable the default
system path search.
* Change: In various flex scanners add the %nounput to suppress
compiler warnings.
* Change: Little cleanup for g++ 4.8.1 as it's more strict.
* Change: In various top CMakeLists.txt, suppress extraneous '/'
after DESTDIR.
Documentation restructuration:
* Bug: in <hurricane>: bad figure for transf-R1.
* Change, in <kite>: Remove deprecated configuration variables.
* New: documentation <tool> to regroup all documentation not directly
related to one tool.
* Change, in <crlcore>, move the user's guide and the top doc index
into <documentation>.
* New, in <documenation>: added Python script demo based on AM2901.
