* 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 Bora::SlicingNode::clearGlobalRouting(), as we are unrouting the
cell, the flags set up by Katana must be reset. The Cell is no longer
"Terminal" and it's nets are "Un-flattened".
* 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).
* Bug: In Bora/SlicingDataModel, the division was done with integers,
leading so there was a rounding *before* we casted to double.
Now, use the BoxSet::getRatio() method and cast to double *before*
dividing.
* 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.
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.
* 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.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.
* Bug: In Bora::BoxSet::destroy(), perform the actual destroy only when
the reference count reaches zero.
In Bora::HVBoxSet CTOR, when duplicating the vector<BoxSet*> arguments,
we must increase the refcount of the all the BoxSet.
The refcounting mecanism of the BoxSet & NodeSet is badly implemented
and should need a full reviewing and redesigning.
* Change: In Hurricane::Isobar/PyHurricane.h, make the hash function use
the DBo id whenever possible instead of the object pointer, fall back
to it for standalone objects (Box like one). The DirectHashMethod()
macro generate a C style function (linkage) which call a template
function "getPyHash<>()" that uses a SFINAE mechanism to select
the right variant.
Create two comparison macros DirectCmpByPtrMethod() and
DirectCmpByValueMethod() to customize the comparison for objects that
have C++ operator==(). So now two boxes with the same contents will
be seen equal by Python. For DBo objects we keep the previous
comparison by C++ pointer.
* Change: In CRL::RoutingLayerGauge::getHorizontalGauge(), when selecting
the default gauge, try, if possible to avoid the PinOnly one.
Same goes for the vertical one.
* Bug: In Katana::TrackCost CTOR, symmetric track axis position was wrong,
was using the reference instead of the symmetric.
* Bug: In BoraEngine::updatePlacement(), set up the Dijkstra search halo
to one pitch so it can use immediately neighboring channels.
* New: In BoraEngine, added python startup hook like in Katana. Mainly
to setup debug nets.
* 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.
* In CRL::Cyclop/CMakeLists.txt, add *again* the MOC files to the list
of .cpp . Don't know what is happening here with MOC under Qt 5.
* In CRL/python/helpers.io, cleanly fails if neither PyQt 4 nor PyQt 5 is
found. And tell it directly because this the module tasked to handle
the exceptions/errors...
* In Cumulus/plugins/AboutWindow.py, try PyQt 4 then PyQt 5.
* In documentation/UsersGuide, now tells explicitely that Qt 4 must be
used under RedHat 7 and Qt 5 under Debian.
* Change: To allow multiple tools, and not only Knik, to link and use
FLUTE, remove it from Knik and put it at top level.
Bootsrap must compile this new tool and the library must be
included in all CMakeLists.txt depending on Knik (and soon
Anabatic).
* New: In Hurricane::RbTree, template for red-black tree. Standard
implementation but well integrated in the Hurricane database and
ready to be derived (both iterator and Collection support).
* New: In Hurricane::IntervalTree, template for interval tree, derived
from RbTree.
* New: unittests tool to perform unit tests.
* Change: In Bora::ChannelRouting, now implemented with IntervalTree.
There is something suspicious here : the "thick" version of
addWireoccupation() seems never to be called. Have to check the
wide wire support implementation.
* 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.
