Groudwork for routing density driven placement. Compliance with clang 5.0.1.
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.

Migration towards Python3, first stage: still based on C-Macros.
* 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.

In Anabatic, correctly set the wire width according to the routing gauge.
* New: Anabatic::AutoContact::setLayerAndWidth() to set both layer and
VIA width/side according to the RoutingGauge. If the delta in zero,
use the metal gauge, and the VIA gauge otherwise.
* Bug: In Anabatic::AutoContactTerminal, Anabatic::AutoContactTurn,
Anabatic::AutoContactHTee & Anabatic::AutoContactVTee, in the
updateTopology() method, set both the layer and the VIA with when
there is a change of layer. Note that this default size may be
overriden later by updateSeize() in the case of non-default width
segments.
* New: In Anabatic::AutoSegment, new overload setLayer(size_t) to set
both layer and segment with according to the routing gauge.
* Bug: In Anabatic::AutoHorizontal and Anabatic::AutoVertical, in method
_makeDogleg(), make use of the new setLayer() to correctly set up
the wire width.
Idem for Anabatic::AutoSegment::changeDepth() and ::makeDogleg(),
and in Anabatic::LayerAssign.

Second version of the antenna effect protection.
* Change: In EtesianEngine::globalPlace(), disable the call to
antennaProtect(). First reason is that, after all, Coloquinte
do not handle so well the resizing of the cells "on the fly",
it overspill the boundaries sometimes. Second reason is that
as we cannot know the routing tree at this stage, we will not
be able to choose the correct points for diode insertions.
We only have a Steiner tree wich may not be the same as a
density driven Dijkstra.
* Change: In Etesian::Area, the Occurrence to the Instances where
not stored in a uniform way. Some where starting from the
placed sub-block, some where starting from the top level
(corona), making their processing (and remembering it) tricky.
Now, they are all expressed from the top cell (corona).
The coordinate system is now systematically the one of the
top block (*not* the block).
Create various overloaded functions EtesianEngine::toCell()
and EtesianEngine::toBlock() to ease Occurrence & coordinate
translations.
* New: In Etesian::Slice::createDiodeUnder(), add a X position hint.
Search is done by going through the whole slice range and
minimizing the distance to the hint. If it starts to be too
slow, we may optimize.
* Bug: In EtesianEngine::toColoquinte(), the placement of the top
level external pins was not taken into account (this at last
explain their weird positioning).
* New: AnabaticEngine::antennaProtect(), new algorithm to avoid
antenna effect. This step must be done *after* global routing
and *before* detailed routing. This way we have access to the
real routing and can mend it (along with the netlist) to
insert diodes at the rigth points.
From the global routing we build clusters (DiodeCluster) of
RoutingPads connected through a set of wire whose total length
is below the antenna effect threshold. Long wires connecting the
clusters are also tagged because we need to put a diode between
them and the first RoutingPad of the cluster. This is to avoid
a long METAL2 wire connecting to the RoutingPad before the diode is
connected through METAL3 (in case of misalignment).
This protection is not even enough. For *very long* wires, we
needs to put *more* than one diode (this is to be implemented).
