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.

Capacity managment by layer in Edges & GCells (plus fixes). * New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities of an edge by layer. This needed now because with real technologies layers capacities differs (unlike with symbolic technologies). This object is separated to be shared between Edges with identical characteristics (direction+interval). Deletion is automatic and done through refcounting. All the already allocateds EdgeCapacity are kept into a set in the AnabaticEngine (key is (direction,interval)). * New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity object. The total capacity can be annotated (i.e. decreased). EdgeCapacity attribute is created during the materialize() call. The capacities are computed at this time. The incCapacity() function is renamed in reserveCapacity(). * New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut to store the shared EdgeCapacity. Lookup/Creation of an EdgeCapacity is done through _createCapacity(). * Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges). * Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity(). This modification did expose a bug in the density calculation : per depth density where divided by the complete density instead of the density's depth. This was leading to greatly underestimated densities. Thoses underestimations where preventing Dijkstra and layer assignement to manage congestion correctly (in fact, it was acting as if there never was congestion). Also avoid a divide by zero (thus -NAN showing in densities). * Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more accurate forceEdgesCapacities(). Note for Eric: only the first Edge on each side has it's capacity forced. What if there's more than one Edge ?

In Anabatic/Katana, add support for VH gauges (real technos). * Change: In Anabatic::AutoContactTerminal::getNativeConstraintBox(), when the anchor is a RoutingPad (which must be always the case), perform the true computation of it's position based on the segment occurrence. It is a important change, previously the area was in fact the "center line" of the connector while now it is really an area (mandatory for "half-offgrid" terminals of real technologies). The change is not complete yet, the area should be shrinked by the half size of a VIA, because the area applies to the center coordinate of the VIA (to be done quickly). * Bug: In Anabatic::AutoContactTurn::updateTopology(), when a dogleg is created (restore connexity after a layer change) the layer of the VIA, based on the segments it connects to must be re-computed *after* the dogleg has been made. * Change: In all files of Anabatic, when comparing two layers, no longer use the Layer pointer itself, but the layer mask. This allow a transparent management of both real and symbolic layers (which do share the same mask). Real metal layers (not VIAs) will be BasicLayer and symbolic metal layers will be RegularLayer. * New: Anabatic::Configuration::selectRpComponent(), select the best RoutingPad component for metal1 terminals. Look for the metal1 component with the biggest accessibility on-grid. RoutingPad using other metals are left untoucheds. * New: New function Anabatic::Vertex::getNeighbor(Edge*) to get the neighbor Vertex through an Edge*. This method allows to write clearer code as we no longer need to access the neighbor through the underlying GCell. Also add proxies for GCell methods in Vertex. * Bug: In Anabatic::Dijkstra::_toSources(), in the ripup stage, when a component with multiples vertexes is reached *and* two of it's vertexes are reached *at the same time* (one from which we backtrack and one still in the queue) extraneous edges may be created by _materialize(). Case occurs on snx/c35b4, "abc_5360_n903_1". To solve this, Dijkstra::_toSource() is modificated, the "from" edges of the newly reacheds vertexes are reset to NULL, *except* for the one we will be backtracking from. That is, the one given in the source argument. * Change: In Anabatic::NetBuilder class, put the various Hooks and RoutingPad sorting functions as class ones. * Bug: In AutoSegment::setLayer(), raise the SegInvalidatedFayer flag. This unset flag was causing AutoContactTurn::updateTopology() to not work as expected and making gaps, this was the cause of the last remaining warnings about layer connexity.

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).
