First stage in analog capacitor integration * 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.
