* Change: In all tools supplying documentation, as we use some specific
software to create the doc, they may not be available, or worse, be
and incompatible version. So, by default, we install the files shipped
with the git repository. To force a full doc rebuild, use the "--doc"
flag of ccb.py.
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
segments (X routing). Althought they have source & target, they
are not articulated like Horizontal & Vertical, due to the
combined displacement of X and Y (diagonal).
Maybe we should create a common class for all the polygons
to make "::getContour()" a method.
Now we could represent self capacitances and high frequency
wires.
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
Add support for convex polygons. Polygon are approximateds by
excess by a manhattan rectilinear polygon (with potentially
thousands of vertexes). To reduce the memory footprint,
compaction techniques reducing by at least a factor 4 has been
implemented. We could go further by only storing the non-repetitive
part of the edge (defined by the integral fraction dY/dY).
We will see, if the program slows too much.
The manhattan approximate is always computed but displayed
only if the polygon grid step is greated than 4 pixels.
The level of approximation of the polygons can be controlled
through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
all DbU related parameters into "technoConfig" (i.e. suppress
"viewerConfig"). Update all the relevant technology.conf configuration
files.
Change the loader behavior so that "technoConfig" is read first
and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
a comprehensive test of the polygons (check all slopes, clockwise and
conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
Support for the "polygonStep" parameter.
* 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.
* Test: post-receive hook on server should send mail [1].
* New: In VLSISAPD, in Parameter, callback have now a tag, which the
pointer to the caller. This allow for the callback removal when
the caller is destroyed.
* New: In VLSISAPD, in WidgetDescription, when associated to a parameter,
the destructor must remove the associated callback function on
the Parameter.
* New: In Hurricane, added JSON support for Configuration, separated
from vlsisapd, as the support is not available at this point.
JSON support for Configuration, Parameter & LayoutDescription.
* Change: In Hurricane, in JsonStack, the stack of JsonObjects has been
displaced here from HurricaneHandler. This way, all
JsonObject::toData() can access the JsonOjects in the context
of the parser.
* New: In Hurricane, in DBo::toJson() added support for Entity by
reference (ids).
* New: In Hurricane, added JSON support for all Layer sub-class types.
* New: In Hurricane, in Technology, export the Layers, but must be
sorted by increasing mask value.
* New: In Hurricane, in Entity, added support for Entity by reference (ids).
* New: In Hurricane, in DataBase, added technology full support.
* New: In Hurricane, In JsonNet, move the ring rebuild management from
JsonStack to JsonNet.
* New: In Hurricane, added JSON support for NetAlias, NetExternalcomponents
(not cleanly implemented as a Relation).
* New: In Hurricane, new method Cell::fromJson() to load a cell from
a JSON file.
* New: In Hurricane, In Graphics, make it an observable, for when JSON
fully reload the graphic state, it must be able to notify other
objects (namely the Controller).
* New: In Hurricane, in ControllerWidget, observe the Graphics to regenerate
the palette as needed. New method ControllerTab::graphicsUpdated().
* New: In Hurricane, in RawDrawingStyle added a destructor to release the
Qt pen/brush. Added JSON support for HSVr, DrawingStyle, DrawingGroup,
& DisplayStyle.
* New: In Hurricane, in GraphicsWidget, rewrite correctly the readGraphics()
to erase the previous widgets and re-create the new ones.
* New: In Hurricane, in PaletteWidget, correct re-creation of the layout/widgets
in case of Graphics change.
* New: In CRL Core, in System, register the parameters callbacks with
the address of the object, for later deletion.
* New: In CRL Core, in AllianceFramework, make it observable, to notify
library changes. For the AllianceFramework creation, now allow to
completly bypass the Python initialization system, when we expect
to restore it from a full blob. Added methods to sets the default
RoutingGauge & CellGauge.
* New: In CRL Core, added JSON suppport for CellGauge, RoutingLayerGauge
& RoutingGauge.
* New: In CRL Core, in LibraryManager, oberver AllianceFramework, to update
the list of libraries in case of change (for JSON full reload).
* 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.
* New: In Hurricane, in Cell & Instance, add the ability to merge the
QuadTree when *second level* instances of a Cell are placed in
the same space as the top Cell. This is the case of a deeply
hierarchical design made of only standard cells that are to
be placed in a "flat" manner.
The design is uniquified then the intermediate instances models,
which should be unique at that point have their QuadTree merged
through a call to Instance::slaveAbutmentBox(). That method will
make the model of the instance use the QuadTree of the Cell to
which the instance belong. The instance model no longer posseses
a dedicated QuadTree. As a corollary the abutment box of both
Cell are kept identical and the Instance has it's transformation
set to (0,0,ID).
Remark: when we talk about "QuadTree", we mean in fact the
QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
Consequence in Query: when going through the resulting
"flattened" QuadTree we will find objects with an incomplete
Path du to the fact that we didn't have to explore their
Instance/Cell level to reach them. The shunted part of the
Path is stored in the Go master Cell in the _shuntedPath
attribute. This also affect the displayed depth of hierarchy,
but not too badly.
* New: In Hurricane, in Cell, new methods:
- Cell::updatePlacedFlag() : set the placement flags.
- Cell::isUnique() : one or less instance.
- Cell::isUniquified() : is the result of an uniquification.
- Cell::isUniquifyMaster() : is the reference cell of the
uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
if it is unplaced. We do not need to duplicate placed Cells
(see datapathes).
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
iterate over all the aliases names (this *not* include the main
net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
uniquification (update documentation).
All Cells that are uniquified from a given model are kept in an
Uniquify relation. This relation allows to get all the clones and
generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
a partially loaded Cell in case of parser failure, let the incomplete
Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
statistics.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
copy some files like the javascripts and some images (open.png,
closed.png). So we copy them from doxygen installation and make
the CMakeLists.txt install them. I hope they will not change too
much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
correctly the formating we already adopted (with a left margin
to put command into). Use HTML_EXTRA_STYLESHEET instead of
HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
top header. Enable dot for inheritance diagram. Set the
EXAMPLE_PATH=. to include the synthetic hierarchy.
Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.
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.
Project hierarchy reorganisation:
* With svn, we were doing a tool by tool checkout, suppressing the
whole repository hierarchy level.
* The tools were also grouped, inside one repository, into multiple
projects (<bootstrap>, <vlsisapd>, <coriolis>).
* We do not want to split up each tool into a separate repository,
given their tight integration (except for vlsisapd).
* We choose to simplify, and consider all tools in a svn repository
one project. Due to the way Git clone repositories, the directory
containing the project is now to be seen under "src/".
CMake modifications:
* Now that the <vlsisapd> and <bootstrap> projects are merged into
coriolis, modificate the top CMakeLists.txt of each tool to uses
only Coriolis (and bootstrap hard wired).
CCB compile script modifications:
* Uses the new source tree hierarchy, with the project directory
inserted.
* Remove (comment) all parts relateds to svn managment.
* Git is sufficiently simple so that we do not want to integrate
command shortcut into the script.
SVN cleanup:
* Remove the obsolete <chamsin> tool, that has become the full fledged
<chams> project long time ago.
- New: Added an id on DBo, SharedName and SharedPath to ensure
database determinism. All the hash key now uses the id instead
of the object's pointer (see _getHashValue()).
- Change: In RoutingPad, position is now only relative to the anchor,
no more (dx,dy). Add a isPlacedOccurrence() to check if all the
occurrence in the path are fixed and thus the position meaningful.
* ./hurricane/doc/hurricane:
- Change: In Cell, added doc about PlacementStatus.
- Change: In Transformation, more detailed explanations about the
orientations. A little beautifying too...
- Change: RoutingPad doc update.
- Change: Entity doc update (for id).
- Change: In HTML header/footer uses the new SoC.css.
- New: In hurricane/doc, added documentation RoutingPad, HyperNet & Query.
- New: In isobar, added support for RoutingPad.
- Change: In PyComponent, getCenter() method moved to it's right place in
the base class.
- Change: In PyPath, added duplicated methods (ApplyOn <-> applyOn and
Invert <-> invert).
- A complete sweep of cleanup to suppress allmost all compiler warnings.
* ./hurricane/doc/hurricane:
- New: Documentation cleanup and update, particularly on the new Layer
derived classes.
* ./hurricane/src/hurricane,
./hurricane/src/isobar,
./hurricane/src/viewer:
- New: Creation of new methods, more explicit on DbU. Based on a to/from
naming scheme.
- New: Python support extented to include all objects needed to configure
through python scripts.
- Change: Finally understood what's causing the _XOPEN_SOURCE redefinition.
Basically the Python.h must be included first before any other
include. The type-puned problem will remains still (that is a Python
problem, not our own).
- Change: In DisplayStyle, uses shared_ptr for DrawingStyle instead of
custom made reference count.
- Change: adopt a tree layout compliant with the UNIX FHS.
* includes under TOP/include/coriolis2.
* shared datas under TOP/shared/coriolis2.
* docs under TOP/share/doc/coriolis2.
* configuration under TOP/etc/coriolis2
* ./crlcore:
- Change: In Environment, comply to the new tree layout, search configuration
files under TOP/etc/coriolis2/.
* ./knik:
- Change: In flute, comply to the new tree layout, get the "POW*.dat" files
from TOP/share/coriolis2/flute-2.4.
- Change: In the CMakeLists.txt, in all the install commands remove all
the leading "/" as they prevents the CMAKE_INSTALL_PREFIX to be took
into account. It was nevertheless working because buildCoriolis.py was
using DESTDIR which is prepended anyway.
* ./goodies:
- Change: In buildCoriolis.py, no longer uses the DESTDIR but instead
CMAKE_INSTALL_PREFIX.
- Bug: In the various Property sub-types dox file the Hurricane namespace
wasn't closed, resulting in the deseapearance of thoses classes in the
documentation (painful to diagnose).
Still, the doc for the derived Property mostly remains to be written.
- Bug: clearing some remnants of a merge conflict in DataBase.dox.
- New feature : first try at a more ergonomic interface. The "Controller",
a simple Tabbed window for managing all settings.
Reorganize the way things are selected (Nets, Area, single), aglomerated
selection.
Use a "logical" progression Netlist -> Selection -> Inspector.
- In CellWiddget, new Selection managment mecanism to ensure persistent
Selection across cell modifications.
New signals/slots to manage Cell modification :
a. - cellPreModificated() : must be launched *before* the Cell modification
by the tool about to modify it.
b. - cellPostModificated() : must be lauched *after* the Cell modification
This mecanism may be amended to automatically fit with the UpdateSessions.
- Cleanup (part 1) : more consistent name for widgets, replace the 'H' prefix by
a "Widget" suffix. Objects are modified by not filenames yet (due to svn not
liking file renaming and modications at the same time).
- Improved support for static building in CMakeList.txt.
- API : in CellWidget & CellViewer constructors now only takes the
parent QWidget.
- Renaming coordinates translation functions for more clarity.
- Adding a StatusBar showing mouse coordinates.
- Documentation of DbU, replacing documentation of Unit.
* ./hurricane/src/hurricane/hurricane/DBo.h :
- Property set is now a mutable member, allowing const DBo to changes
their properties. Strange side effect on SlotAdapter in which we
need to declare two separate templates, one for const type and
another for non-const type.
- _getTypeName() defined to prevents noisy error message when a
derived class (from DBo) do not want to implement support for
the inspector.
- Unit evolution to allow Symbolic (lamda) and Real (grid founder) mixing.
All functions related to Unit translations are now grouped under
the "DbU" class (another tribute to OpenAccess). "DbU" contains
only static attributes (constants) and methods. Unit itself becomes
a typedef inside this class, hence the file renaming from Unit.{h,cpp}
to DbU.{h.cpp}. Have to replace all instances of "Unit" by "DbU::Unit".
- Doc will be updated shortly.
- CompositeLayer replaced by 5 kind of symbolic layers :
RegularLayer (1 BasicLayer)
DiffusionLayer (2 or 3 BasicLayers: active+implant,well)
TransistorLayer (3 or 4 BasicLayers: poly+active+implant,well)
ContactLayer (4 or 5 BasicLayers: metal+cut+active+implant,well)
ViaLayer (3 BasicLayers: metal0+cut0+metal1)
- To better follow the OpenAccess semantic, the "obstacle" Material type
is renommed to "blockage".
- NB: doxygen documentation is not up-to-date and issue warnings.
* ./coriolis/src/crlcore :
- Migrate from CompositeLayer to the various SymbolicLayers.
- Symbolic rules are now closer to the reality so that a Cell displayed
with Hurricane should look identical to the Graal one.
- Complete rewrite of the AP parser. Much simplificated, do not try to
merge/articulates segments. This ensure a true rendering of the
Cell. Especially do not create contact to anchor diffusion segments,
which leads to very strange randering (DRC error as well).
./hurricane/doc/hurricane/src/hurricane/BasicLayer.{h.cpp}
- Changed "Type" to "Material" to fit better the OpenAccess semantic.
Introduce Material meanings : pWell, nWell, pImplant, nImplant
active, metal, cut, obstacle & other.
* ./coriolis/src/crlcore :
- Switched to the generic layer model. Updated technology XML configuration
files, technology parser & AP parser/driver.
- Note that the representation of transistors visually changes as it's now
modelled with Implant + Active.
- Added (empty) directories "html" & "latex". Those directories are
created by doxygen, but as they are used in the CMakeList.txt, they
must be present even before the fisrt run of cmake (otherwise cmake
choke on them).
- Doxygen sets to only generate html & pdf (through LaTeX) documentation.
- All ".dox" files corrected to suit the new function members naming
scheme (some work may remains in code examples).
