* 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.
* New: Added multiple clock support in H-Tree generation in alpha/block.
* New: In CRL/etc/<NODE>/<TECH>/plugins.py, added three new parameters
for block plugin config:
"block.spareSide" : The size of the minimum side of a buffered area.
(quad-tree leaf).
"spare.buffer" : The model of the cell buffer to be used.
"spare.maxSinks" : max number of sinks on a buffer before issuing
a warning (non-blocking).
* Bug: In Etesian::BloatCell::getAb(), never apply the bloat profile to
fixed cells. In case of buffers from the spare maxtrix it was leading
Coloquinte to detect an overlap of fixed cells, which it do not
support (rightly so).
* Change: In CRL/helpers/__init__.py, to ensure a complete restart of
the database the __init__.py must be called again, but it's not the
case with reload() (see Python doc). So helpers.resetCoriolis()
must explicitly removes the Coriolis related Python modules from
sys.modules (calling "del sys.modules[moduleName]").
That list of Coriolis Python modules is built by calling
helpers.tagConfModules(), it will tag all modules added to
sys.modules since startup. It will remove (much) more than
Coriolis modules, but that should be ok.
* Change: In CRL/etc/{node*,symbolic}/TECH/__init__.py, add a call to
helpers.tagConfModules() for the techno modules to be erased on
reset.
* Change: In CRL::LefParser::_macroCbk(), create a Catalog entry for the
newly read MACRO (that is Cell) and sets the Logical, Physical,
InMemory and TerminalNetlist flags.
* Bug: In CRL::LefParser::_siteCbk(), check for NULL cell gauge.
* New: In CRL::AllianceFramework, add setCellGauge(), to set the default
cell gauge. Exported to Python.
* Change: In CRL/etc/common/technology.py, create variables for VIA
layers, so we can modify their properties afterwards.
* New: In CRL/etc/node45/freepdk45, port the configuration files to the
new Python "importable" format.
Note: in kite.py, all the gauges (Routing & Cells) must be named
"LEF.CoreSite" to please my LEF parser, so it can match the gauge
name with the SITE name for standard cells.
* Bug: In Anabatic::NetBuilderVH::_do_2G(), forgotten to be reimplemented
from the base class. Simply redirect to _do_xG().
* Change: In Katana::PowerRailsPlanes::PowerRailsplanes(), create plane
from the layers in the RoutingGauge and their associated blockages
instead of sweeping through all the basic layers.
Allow to distinguish bewteen "METAL" (symbolic) and "metal" (real).
