* Change: In Cumulus/plugins/core2chip/CoreToChip.py, in IoNet select
the external I/O net (pad connected) signal to be generated in the
context of the I/O pad instanciation. This should allow an enable
signal in one pad to be also used in a direct output pad.
* Change: In Hurricane::Error constructors disable the backtrace generation.
(*very* slow).
* Change: In Hurricane::Library::getHierarchicalname(), more compact
naming. Remove the name of the root library.
* New: In Hurricane::Net, new type "FUSED", for component with no net.
More efficient than having one net for each.
* Change: In CellViewer, BreakpointWidget, use Angry Birds icons.
* Change: In CellWidget::State, use the hierarchical name (cached) as key
to the state. This allow to load two cells with the same name but from
different libraries in the widget history.
* Change: In PyGraphics, export "isEnabled()" and "isHighDpi()" functions.
* Change: In CRL/etc/symbolic/cmos/plugin.conf, and
CRL/etc/common/plugin.conf use the physical dimensions converters.
* Change: In CRL/etc/symbolic/cmos/technology.conf, make the GDS layer
table coherent with the default Alliance cmos.rds.
* New: CRL/python/helpers/io.py, put ErrorMessage new implementation here,
along with a new ErrorWidget written in PyQt4. It seems finally that
PyQt4 can be used alongside Coriolis Qt widgets.
New ErrorMessage.catch() static function to manage all exceptions
in except clauses.
* Change: In CRL/python/helpers/, no longer use ErrorMessage.wrapPrint(),
directly print it.
Rewrite the utilities to display Python stack traces "textStacktrace()"
and "showStacktrace()".
* Change: In CRL::AllianceFramework, shorten the names of the libraries.
* Change: In CRL::ApParser & CRL::ApDriver, more accurate translation between
Alliance connectors (C record) and Hurricane::Pin objects. Pin are no
longer made square but thin and oriented in the connecting direction.
Use the new fused net for unnamed components.
* New: In CRL::GdsParser, implementation of SREF parsing, i.e. instances.
Due to the unordered nature of the GDS stream, instances creation are
delayed until the whole stream has been parsed and only then are they
created.
For the sake of reading back Alliance s2r GDS, we assume that any
TEXT following a boundary is the Net name the boundary (component)
belongs to.
Create abutment box for Cells, computed from the bounding box, so
the Hurricane QuadTree could work properly.
Make use of the fused net for unnamed components.
* New: In Cumulus/plugins/chip, complete rewrite of the I/O pad management.
Now we can mix real (foundry) pads and a symbolic core.
To cleanly support the de-coupling between the real part and the
symbolic one we introduce a new intermediary hierarchical level, the
corona. We have now:
Chip --> Pads + Corona --> Core.
At chip level (and if we are using real pads) the layout is fully
real (excepting the corona).
The Corona contains everything that is symbolic. It has symbolic
wires extending outward the abutment box to make contact with the
real wires coming from the pads.
In the pad ring we can use corners instances (or not), pad spacers
or directly draw wires between connectors ring pads.
Provide two flavors: placement only or full place & route.
WARNING: If routing in a second step, *do not route* the *Chip* but
the *Corona*.
* Change: In Cumulus/plugins/clocktree, give the modified Cell an
additional extension of "_cts" (Clock Tree Synthesis) instead of
"_clocked", to follow the common convention.
* New: In cumulus/plugins/S2R.py, encapsulate call to Alliance S2R and
reload the translated Cell in the editor.
* New: In cumulus/plugins/core2chip, provide an utility to automatically
create a chip from a core. To work this plugins must have a basic
understanding of the pad functionalities which may differs from
foundry to foundry. So a base class CoreToChip is created, then for
each supported pad foundry a derived class is added. Currently we
support AMS c35b4 and Alliance symbolic cmos.
* Bug: In Anabatic::Configuration, read the right configuration parameter
"anabatic.topRoutinglayer" (Katana), and not the one for Katabatic...
* Change: In Unicorn/cgt.py, process the plugins in alphabetical order
to ensure a reproductible ordering of the menus...
* Bug: In CRL/etc/symbolic/cmos/plugins.conf, rails dimensions are no
longer expressed directly in lambda. Must be created using helper.l().
* Change: In CRL::ApParser, slightly more smart management of Pin width.
Must normalize Pin behavior between Alliance & Hurricane as in
Alliance they have only one dimension.
* Change: In CRL::LefImport, if a net name end with "!", assume it's a
global one. Have to check this naming convention.
* Change: In Anabatic::NetBuilderHV::_do_1G_1PinM3() & _do_1G_1PinM2()
now implemented. Needed for the corona routing support.
* Change: In AnabaticEngine::setupPreRouted(), exclude segments outside
the abutment box.
* Change: In KatanaEngine::PowerRails, remove the I/O pad support as now
we route only inside the Corona. So only one vdd/vss/ck are supported.
* New: In cumulus/plugins/ChipPlugin.py, complete rewrite of the chip
support:
* Uncouple pad I/O ring whith real cells (foundry) from a symbolic
core. A new intermediate level "corona" is introduced to handle
the real/symbolic transition.
* Ability to explicitly setup position of the pads on the chip side
in case of uneven distribution.
* Enable clock tree to be build with 3 metal only (M2 to M4) instead
of (M2 to M5).
* New: In Hurricane, In Net & Cell, support for Net aliases names.
Use a structure based on a simple ring of NetAliasHook. The Net
holds a global map, sorted by names of all the aliases of all Nets.
Elements NetAliasesHook of the map are slaves of ring whose master
is an attribute of the Net (it is *not* in the map, as the primary
name of the Net).
In case of merge, the aliases of both Nets are merged and the
name of the merged one become an alias.
The Cell::getNet() looks in both the Net map and the aliases to
find a Net by name.
* Bug: In CRL Core, in coriolisInit.py, reoder the loading of the
configuration files so the real technology is read as early as
possible to set up the <gridsPerLambda> factor before any lambda
is actually computed...
* Bug: In CRL Core, in AcmSigda, do not try to fed the file when it
has failed to be opened. Throw a clean exception instead.
* New: In CRL Core, in Toolbox, add a NamingScheme object to convert
a design into VHDL compliant names (mainly from Blif/Verilog).
This is extensible in any case.
* New: In CRL Core, in BlifParser, slightly more informative warning
messages. Align the loading progress information on the other
parsers.
Add a capability to select which component of the design will
be returned, if there are more than one. Use the "." as separator.
For exemple you can request "Processor.Alu", which will load
the "Alu" component from the design in "Processor.blif".
To be able to save a Blif loaded design, systematically convert
all the name for VHDL compliance, as it is the format used by
the Coriolis native files (vst).
Export the Blif parser to the Python interface.
* New: In Kite, In NegociateWindow, add a counter of the number of
remaining events. Gives an idea of the ETA...
* New: In Unicorn, in cgt.by, add an option to load a Blif design from
the command line.
* New: In Cumulus, new RSave plugin to save both netlist & layout.
Partly redundant with the previous one. Have to better organize
that later.
* Change: In Hurricane, the NetRoutingProperty is moved into Hurricane
from Katabatic. Needed for Knik to be able to access thoses
informations.
* Change: In Hurricane, in RoutingPad::setOnBestComponent(), now in
case of identical area, select the component of lowest id.
This should not be needed if the component ordering was fully
deterministic as it should be (will investigate later).
This is to ensure that the choosen component is always the
same, especially between save/load of a global routing.
* Bug: In Katabatic, in AutoContactHTee::updateTopology(), invalidate
the segments only if the topology is valid (no NULL in the
cached segments).
* Bug: In Katabatic, in GCellTopology::construct(), throw an error
if the topology is bad instead of trying to continue (and core
dump later... ).
* Bug: In Kite, in BuildPowerRails, distinguish the name of the master
net in the pad (for vddi, vssi, vdde, vsse, ck, cki & cko) and the
name of the net in the *chip* netlist. Must use the later to make
comparison as they may differs.
* Change: In Knik, in save/load solution, exclude nets that are not
globally routed by Knik. That is which NetRoutingProperty is not
*Automatic*.
* Bug: In Cumulus, in chip.BlockPower take account of the layer
width extention to sligthy shrink the connector thus avoiding a
notch with standart cell in some cases.
* Change: In Cumulus, in chip.ClockTree disable the use of fixed Steiner
trees for the leaf clocks, as it seems overconstrained for the
router. First move was to lower them in M2/M3 (instead of M3/M4)
but that was not sufficent.
* New: In Cumulus, RSavePlugin for recursively saving a physical
hierarchy.
* New: In documentation, first embryo for RDS file. Should have been
in Alliance git, but I prefer to keep newest doc in Coriolis.
* New: In Cumulus, first versions of the ClockTree and Chip plugins.
Clock Tree plugin:
- It is strongly advised to use have 4 metal routing layers for the
tree to work. Otherwise, problems can arise with the detailed
routing (fully obstructed terminals).
- H-Tree can only be build (for now) for design with a form factor
between 0.5 an 2.
- The tree is created at the block top-level and only the leafs are
trans-hierarchically created on the instances/models. The new
cell with a clock tree, along with all it's sub-models is created
with a "_clocked" suffix.
- Leaf cells are connected through a simple Minimum Steiner Tree.
- Shorts are avoided by a systematic shift of the wires according
to their kind. No wire must pre-exist. When used as a sub-module
of "chip" the wires cannot be moved. When created on a block,
the wires can be loaded in the detailed router as manual global
router.
Chip Plugin:
- Perform the pad placement and corona creation. Replacement at
last of the clunky code from Wu Yifei.
- Relies on a Python configuration file '<design>_chip.py' with
a "chip" dictionnary.
* New: In Cumulus, new Alliance.py module (*not* a plugin) providing
an encapsulation for Alliance command line tools. The other main
feature is that it provides a "Makefile like" behavior. Based on
the command dependencies a DAG is contructed, then a static
ordering of the commands. Commands are then executed to rebuild
outdated target.
The Alliance environment supplied to the commands is read from
the Coriolis configuration file <alliance.conf>.
For this first evaluation version, only <boom>, <boog> and
<loon> support are provided.
It still not clear how to encapsulate the Coriolis tools in
the same way.
* Change: In CRL Core, in helpers/__init__.py, change the way the static
initialization (module) is done. All the commands are put inside
a "staticInitialization()" function, which is then explicitly
called by others. This is a better solution agains *no* or *twice*
initialization. Modificate <coriolisInit.py> accordingly (as
<Alliance.py> from Cumulus.
Finally get rid of the demonic code from Wu Yifei...
* New: In Isobar, added encapsulation of Interval (don't know how have
forgotten it for so long).
* Change: In Isobar, In PyLayer, new PyLink_LayerDerived() function to
create/link the C++ object to the correct derived class and not the
base one (PyLayer) which then prevent to use the specialized methods.
Must replace PyLink_Layer() througout all the code.
* Change: In Isobar, in PyPoint the "setX()" & "setY()" methods where
still capitalized.
* Change: In Isobar, in PyQuery, complete the exportation of the C++
interface. remove the code belonging to a more "boost" way of
building the Python interface (will do that in a far future).
* New: In CRL Core, In PyAllianceFramework, export isPad() method.
* Change: In Unicorn, in unicornInit.py, protect the loading of each
single plugin by a "try" / "except" clause to the failing of one
plugins do not stop the loading of the next one.
Pass the same dictionnary argument to unicornHook() as for
ScripMain(), this is more uniform this way.
* New: In Cumulus, complete replacement of the chip placement scripts
from Wu Yifei (at last!). The clock-tree integration is still to
be done.
________________________________________________________________________
* 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 Hurricane, in CellViewer, create a simpler API to graft menu
and actions into the menubar. Mainly addToMenu() which take care of
the QAction creation but also locate the relevant QMenu, base on
the Qt object name. Regroup all the widget & action creation inside
the body of the constructor, this way almost all actions can be
removed from the attributes of the CellViewer.
addToMenu() is supplied in three flavors:
1. For C++ callbacks in GraphicToolEngines (with a binded
member function method).
2. For running Python scripts to be used by the plugin system.
3. To insert separator in menus (to give a more homogeneous
look).
Remove the last remnants of Stratus scripts (unificated with basic
Python scripts).
* New: In Hurricane, in PyCellViewer, export the interface to graft
Python scripts into the CellViewer menu tree.
* Change: In Etesian, in GraphicEtesianEngine, use the new API to
graft menus & callbacks into the CellViewer.
* Change: In Mauka, in GraphicMaukaEngine, use the new API to
graft menus & callbacks into the CellViewer.
* Change: In Kite, in GraphicKiteEngine, use the new API to
graft menus & callbacks into the CellViewer.
* New: In Cumulus, install Python scripts as plugins for Unicorn under
<PYTHON_SITE_PACKAGES>/cumulus/plugins/.
* New: In Unicorn, in UnicornGui, make uses of the new API for creating
menus in the CellViewer. Creates the stem menu for the P&R tools.
Add a Python initialization mechanism to read the plugins
installeds into <PYTHON_SITE_PACKAGES>/cumulus/plugins/.
