Correction in plugins to support msxlib compatible pads. * New: In CRL Core, in helpers & alliance.conf, set and read a "PAD" variable to define the pad model name extension ("px" for "sxlib and "pxr" for vsxlib, this is provisional). * New: In CRL Core, in plugin.conf, add parameters to define the name of used for power & clock supply. We may remove the extention in the future (to be more coherent with the previous modification). * New: In Cumulus, in chip.Configuration.GaugeConf._rpAccess(), no longer place the accessing contact *at the center* of the RoutingPad. It works under sxlib because buffers & registers all have same size terminals. But this is not true under vsxlib, leading to misaligned contacts & wires. Now systematically place on the slice midlle track (maybe with one pitch above or below). This is still very weak as we do not check if the terminal reach were the contact is being put. Has to be strenthened in the future. * New: In Cumulus, in chip.Configuration.ChipConf, read the new clock & power pad parameters. * Change: In Isobar (and all other Python wrappers), uses PyLong instead of PyInt for DbU conversions. In PyHurricane argument converter, automatically check for both PyLong and then PyInt. * Change: In Cumulus, in chip.PadsCorona, more accurate error message in case of discrepency in global net connections (i.e. no net of the same name in instance model and instance model owner. * Change: In Kite, in BuildPowerRails, when looking up at the pads model name to find "pck_" or "pvddeck_", do not compare the extension part. But we still use hard-coded stem pad names, maybe we shouldn't. * Bug: In Katabatic, in GCellConfiguration::_do_xG_xM1_xM3(), there was a loop in the search of the best N/E initial RoutingPad. * Bug: In Kite, in KiteEngine::protectRoutingPads(), *do not* protect RoutingPads of fixed nets, they are already through the BuildPowerRails stage (and it's causing scary overlap warning messages). * Bug: In Cumulus, in ClockTree.HTreeNode.addLeaf(), do not create deep-plug when the core is flat (not sub-modules). All the new nets are at core level. * Bug: In Cumulus, in ChipPlugin.PlaceCore.doFloorplan(), ensure that the core is aligned on the GCell grid (i.e. the slice grid of the overall chip). * Bug: In Kite, in GCellTopology::_do_xG_xM1_xM3(), infinite loop while looking for the bigger N-E RoutingPad.

Merged QuadTrees in overlayed Cells (placed together). * New: In Hurricane, in Cell & Instance, add the ability to merge the QuadTree when *second level* instances of a Cell are placed in the same space as the top Cell. This is the case of a deeply hierarchical design made of only standard cells that are to be placed in a "flat" manner. The design is uniquified then the intermediate instances models, which should be unique at that point have their QuadTree merged through a call to Instance::slaveAbutmentBox(). That method will make the model of the instance use the QuadTree of the Cell to which the instance belong. The instance model no longer posseses a dedicated QuadTree. As a corollary the abutment box of both Cell are kept identical and the Instance has it's transformation set to (0,0,ID). Remark: when we talk about "QuadTree", we mean in fact the QuadTree for the instances *and* the SliceMap (Layer+QuadTree). Consequence in Query: when going through the resulting "flattened" QuadTree we will find objects with an incomplete Path du to the fact that we didn't have to explore their Instance/Cell level to reach them. The shunted part of the Path is stored in the Go master Cell in the _shuntedPath attribute. This also affect the displayed depth of hierarchy, but not too badly. * New: In Hurricane, in Cell, new methods: - Cell::updatePlacedFlag() : set the placement flags. - Cell::isUnique() : one or less instance. - Cell::isUniquified() : is the result of an uniquification. - Cell::isUniquifyMaster() : is the reference cell of the uniquification. * Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only if it is unplaced. We do not need to duplicate placed Cells (see datapathes).

Merged QuadTrees in overlayed Cells (placed together). * New: In Hurricane, in Cell & Instance, add the ability to merge the QuadTree when *second level* instances of a Cell are placed in the same space as the top Cell. This is the case of a deeply hierarchical design made of only standard cells that are to be placed in a "flat" manner. The design is uniquified then the intermediate instances models, which should be unique at that point have their QuadTree merged through a call to Instance::slaveAbutmentBox(). That method will make the model of the instance use the QuadTree of the Cell to which the instance belong. The instance model no longer posseses a dedicated QuadTree. As a corollary the abutment box of both Cell are kept identical and the Instance has it's transformation set to (0,0,ID). Remark: when we talk about "QuadTree", we mean in fact the QuadTree for the instances *and* the SliceMap (Layer+QuadTree). Consequence in Query: when going through the resulting "flattened" QuadTree we will find objects with an incomplete Path du to the fact that we didn't have to explore their Instance/Cell level to reach them. The shunted part of the Path is stored in the Go master Cell in the _shuntedPath attribute. This also affect the displayed depth of hierarchy, but not too badly. * New: In Hurricane, in Cell, new methods: - Cell::updatePlacedFlag() : set the placement flags. - Cell::isUnique() : one or less instance. - Cell::isUniquified() : is the result of an uniquification. - Cell::isUniquifyMaster() : is the reference cell of the uniquification. * Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only if it is unplaced. We do not need to duplicate placed Cells (see datapathes).
