* New: Python/C++ API level:
* Write a new C++/template wrapper to get rid of boost::python
* The int & long Python type are now merged. So a C/C++ level,
it became "PyLong_X" (remove "PyInt_X") and at Python code
level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
* Configuration is now integrated as a Hurricane component,
makes use of the new C++/template wrapper.
* vlsisapd is now defunct. Keep it in the source for now as
some remaining non essential code may have to be ported in
the future.
* Note: Python code (copy of the migration howto):
* New print function syntax print().
* Changed "dict.has_key(k)" for "k" in dict.
* Changed "except Exception, e" for "except Exception as e".
* The division "/" is now the floating point division, even if
both operand are integers. So 3/2 now gives 1.5 and no longer 1.
The integer division is now "//" : 1 = 3//2. So have to carefully
review the code to update. Most of the time we want to use "//".
We must never change to float for long that, in fact, represents
DbU (exposed as Python int type).
* execfile() must be replaced by exec(open("file").read()).
* iter().__next__() becomes iter(x).__next__().
* __getslice__() has been removed, integrated to __getitem__().
* The formating used for str(type(o)) has changed, so In Stratus,
have to update them ("<class 'MyClass'>" instead of "MyClass").
* the "types" module no longer supply values for default types
like str (types.StringType) or list (types.StringType).
Must use "isinstance()" where they were occuring.
* Remove the 'L' to indicate "long integer" (like "12L"), now
all Python integer are long.
* Change in bootstrap:
* Ported Coriolis builder (ccb) to Python3.
* Ported Coriolis socInstaller.py to Python3.
* Note: In PyQt4+Python3, QVariant no longer exists. Use None or
directly convert using the python syntax: bool(x), int(x), ...
By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
* In order to compile user's must upgrade to my own rebuild of
PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
buffer of the H-Tree to the original signal (mainly: top clock).
Strangely, it was only done when working in full chip mode.
* Bug: In karakaze/AnalogDesign.readParameters(), when asserting the
type of dspec[0], it can either be a type (for analog devices) or
a Cell object (*not* a type). So the issubclass may fails.
Now check first if dspec[0] is an *instance* of Cell.
This is an anisotropy in the type of the first element of
the devicesSpecs table, but suppress one superfluous parameter.
* New: In Analog, new Parameter derived class "StringParameter",
to support strings. Also added to the Python interface.
* New: In Analog::Transistor, added StringParameters for specifying
track positions. They are named "G.t", "S.t", "D.t" and "B.t".
* New: In Oroshi/wip_transistor.py, now read the track positionning
devices parameters.
* New: In Karakaze/AnalogDesign.doDevice(), read an optional 14th
parameter holding the track positions (example in ADC-SAR).
* Change: In Karakaze/analogdesign/AnalogDesign.readParameters(),
only Transistor and Capacitors where manageds. So when a devices in
the dspec was from another type, it did issue an error.
Now cleanly skip unsupported (yet) devices.
* Bug: In Hurricane::NetRoutingState::getSymValue(), outrageously bad
computation of the symmetric coordinate when the value was superior
to the axis... (shame on me).
* Change: In Anabatic::Disjkstra::load(), for symmetrically paired nets,
check that the axis of symmetry is *outside* the searchArea.
Otherwise, the two mirrored areas overlaps and the two nets will
unescapably be on top of each other. Issue a warning but still
continue.
* Change: In Anabatic::Vertex::isRestricted(), allow perpandicular
wire to go through struts or thin (less than one routing pitch)
node. May have to recheck in the future and restrict to struts
only.
* Bug: In Bora::HVSlicingNode::updateSymNetAxis(), rescursive call in
child node was not systematically done (bad curly brace position).
Also checks that symmetries are not empty before accessing the
front element (one less core dump).
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
Move towards more Python PEP8 compliance:
* All indentations sets to 4 spaces (in progress).
* In plugins, remove messages about software collections
and RHEL (too many case could wrongly lead to that).
Instead systematically uses "helpers.io.catch()".
* Put in lowercases all modules names. Note that C++ exported
modules *keep* their Capitalized names (to preserve the
identity with the C++ namespace).
* When making import, use full path.
* Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
the one ending in ".conf". Keep those who have not been ported
to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
C preprocessor macros by C++ templates. Applied first to configuration
from VLSISAPD.
This is unfinished business, just a limited demonstrator for now.
It is installed as a separate Python library "Cfg2" which do not
interact with the rest of Coriiolis.
The end goal is to fully remove boost and merge VLSISAPD useful
components directly inside Hurricane.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
"PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
and associated Resistor.py to make parameter conversion.
Currently we only uses vertical layout for resistors.
Added METAL2 horizontal terminals for resistors.
* Change: In Hurricane::DbU::setGridPerLambdas(), allow the grid per
lambda to be even. Needed when using nsxlib libraries that are
drawn using a "half lambda" (two lambdas to get an Alliance lambda).
* New: In Oroshi/python, integrated capacitors. Modifications and
correction from Mariam's code:
* No need to redefine __setattr__() on CapacitorUnit.
* Pitch horizontally & vertically (symbolic routing tracks) the
devices.
* Put the horizontal access tracks on the routing pitch.
* Sets the horitontal metal2 wires as external components and
NOT the capacitor plates themselves.
* Makes the size (plates) of the unit capacitor a multiple of
the foundry grid, not a floating number...
* Correct the net ownership of horizontal tracks in
drawHRoutingTracks().
* Simplification & put error management directly inside of
__isCapacitorUnitOK__().
* New: In Karakaze/python/AnalogDesign, capacitor spec now include
the dummy parameter.
* New: In Karakaze/Oceane.py, now also read capacitor & resistors parameters.
In AnalogDesign.readParameters(), get the capacitor parameters from
Oceane into the "device spec" (dspec). Translate form OSI unit to
Coriolis units (F -> pF).
* Bug: In Bora::NodeSets::create(), Capacitor matrix parameters where never
read due to a misplaced curly brace (at the matrixRange dynamic_cast<>
test).
* Change: In Bora/PyDSlicingNode, now check that the parameter is either
a StepParameterRange or a MatrixParameterRange.
Also add a check that the Instance name exists...
* Bug: In Bora::SlicingPlotWidget::updateSelectedPoint(), as we display
only the transistor parameters in dynamic labels, do not forget to
skip resistor and capacitor. Otherwise we end up in out of bound
access in the vector of labels.
* New: In Analog, added Analog::ResitorFamily & Analog::Resistor classes.
* New: In Analog, added inspector support for all Parameter classes.
* New: In Analog, new FloatParameter class (for resistor value).
* New: In CRL/etc/scn6m_deep_09/devices.py, added resistor device.
* New: In Oroshi, support for Resistors, stub for ResistorSnake generator.
* New: In Bora::DNodeSets, added support for Resistor devices.
* Change: In Bora::DSlicingNode, rename setNFing()/getNFing() into
setBoxSetIndex()/getBoxSetIndex() for semantic coherency.
* New: In Karakaze/python/AnalogDesign.py, added support for Resistor.
Change in addDevice(), the span which was only meaningful for
transistor devices is replaced by a parameter argument.
The parameter argument has to be consistent with the device type.
* Bug: In Technology::getPhysicalRule(), if the named layerdo not exists,
throw an exception instead of silently putting a NULL pointer inside
a rule.
* New: In Hurricane/Analog, new parameters classes for capacitor devices:
- Analog::Matrix, a matrix of null or positives integers to encode
capacitor matrix matching.
- Analog::Capacities, a list of float values for all component of a
multi-capacitor.
* New: In Hurricane::Script, add a "getFileName()" method to get the full
path name of the Python module.
* Change: In Analog::LayoutGenerator, completly remove the logger utility
as it is no longer used. Simply print error messages instead.
* Change: In Analog::MetaCapacitor, rename top & bottom plate 'T' & 'B'.
Accessors renamed in "getTopPlate()" & "getBottomPlate()".
* New: In Analog::MultiCapacitor, complete rewrite. Makes use of the
new parameters "capacities" and "matrix". Dynamically generates it's
terminals as we do not know beforehand how many capacitors could be
put in it.
* Bug: In isobar/PyHurricane.h, in Type object definition, do not prepend
a "Py" to class name (so the keep the C++ name).
* Change: In CRL/etc/scn6m_deep_09/devices.py, add entry for the new
capacitor generator.
* New: In oroshi/python/ParamsMatrix, add a "family" entry in the [0,0]
element to distinguish between transistor, capacitor and resistor.
(this is the matrix of values returned to the LayoutGenerator after
device generation).
Now have one "setGlobalParams()" function per family.
* New: In oroshi/python/Rules.py, added DTR rules needed by capacitors.
Catch exceptions if something wrong append when we extract the rules
from the technology.
* New: In Bora, the devices are no longer *only* transistors, so the
possibles configurations are no longer defined only by a number of
fingers. We must be able to support any kind of range of configuration.
So the explicit range of number of fingers is replaced by a base
class ParameterRange, and it's derived classes:
- Bora::StepParameterRange, to encode the possible number of fingers
of a transistor (the former only possibility).
- Bora::MatrixParameterRange, to encode all the possible matching
scheme for a capacitor. As there is no way to compress it, this
is a vector of Matrix (from Analog).
* Change: In Bora::DSlicingNode::_place(), the ParameterRange has to be set
on the right configuration (through the index) before being called.
The generation parameters are taken from the active item in the
ParameterRange.
* Change: In Bora::NodeSets::create(), iterate over the ParameterRange
to build all the configuration. Adjustement to the routing gauge
pitchs are moved into the DBoxSet CTOR to save a lot of code.
Semantic change: the index in the NodeSets is now the index in
the associated ParameterRange and no longer the number of fingers
of a transistor.
Check that the ParameterRange dynamic class is consitent with the
device family.
* Change: In Bora::DBoxSet, same semantic change as for NodeSets, the
number of finger become an index in ParameterRange.
In DBoxSet::create(), now also perform the abutment box adjustement
to the RoutingGauge, if possible.
* New: In Karakaze/python/AnalogDesign.py, add support for Capacitor
devices.
* Change: In Hurricane::Script, when running a script, no longer do it
inside a Python sun-interpreter, use the current one. This way we
no longer have our modules initialized twice or more, which was
starting to be unmanageable (with the NDA support).
The settings were re-read multiple time to the same value, so it
was working, but still...
I hope I didn't left some dangling Python objects now.
* Bug: In Hurricane::LayoutGenerator::drawLayout(), get the device abutment
box though a Pyhon object *before* finalizing which removes that objet.
* New: In cumulus/plugins/__init__.py, add a "loadPlugins()" and static
initialisation to preload plugins modules.
We use that pre-loading step to append to the module __path__ attribute
the alternate directory where a NDA covered may be found. This assume that
the directory tree under the NDA root is identical to the one under the
public root.
* New: In cumulus/plugins/chip/__init__.py, small utility function
importContants() to import the constants inside another module namespace,
to have more consise notations.
* Change: In cumulus/plugins/, in the various plugins sub-modules import
use the full path from plugins, that is, for example:
from plugins.core2chip.CoreToChip import IoPad
* Change: In Unicorn/python/unicornInit.py, no longer directly load the
plugins modules, this is now done by cumulus/plugins/__init__.py.
Instead, iterate through sys.modules for the ones starting by "plugins/"
and try to execute a Unicorn hook, if present.
* Change: In Karakaze/python/AnalogDesign.py, update for the new Instance.create()
prototype (added placement parameter).
* 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...
* Change: In Hurricane::CellWidget, set the minimal size to 350 pixels
to fit my normal DPI secondary screen...
* Change: In Hurricane::Error(), reactivate the backtrace generation by
default. Seriously slow down the program each time an Error is to
be constructed.
* Bug: In Analog::Device::preCreate(), check for NULL Technology before
attempting to use it.
* Change: In Hurricane/Analog, remove all '*Arguments*' classes and their
Python interface. It was an obsoleted way of passing devices parameters
to the Python layout generators (located in Oroshi). Now we just get
them straight from the Device with the getParamter() method.
* Change: In CRL::System CTOR, add Python pathes for Oroshi & Karakaze.
* Change: In Oroshi/Python/WIP_*.py layout generator scripts, remove
all uses of the "Arguments". Directly access the parameters through
the device itself. Make the checkCoherency() with identical arguments
as of layout().
* New: Bora tool that performs analog place & route. Based on a slicing
tree representation. It is the thesis work of Eric Lao.
Code beautyfication and some programming cleanup.
* New: Karakaze tool, provide the Python base class AnalogDesign used
to build an analog design. Create/configure devices and assemble
them in a slicing tree.
* Change: In Unicorn/cgt.py, display the stack trace in case of an
ImportError exception as well as for other exceptions.
Add Bora to the set for included tool engines.
