* New: In CRL::RoutingLayerGauge, add a new kind of gauge "PowerSupply"
to flag a layer which is dedicated to routing power supplies.
* New: In AllianceFramework, add management of PowerSupply gauge kind.
Exported in the Python interface.
Integrate new features and bug fixes so the Arlet 6502 benchs successfully
passes real DRC with reference industrial tools. Short summary:
* Manage minimum area for VIAs in Katana::Tracks.
* Allow different wire width for wires perpandicular to the prefered
routing direction.
* StackedVIAs used in the clock tree no longer assume an uniform
routing grid (same offset & pitch all the way up).
* Some hard-coded patches in PowerRails for FlexLib.
* New: In CRL/symbolic/cmos/kite.py & cmos45/kite.py, update the
RoutingLayerGauges by adding the new PWireWidth parameter.
Always zero in case of symbolic layout (too fine tuning).
* New: In CRL::RoutingGauge, add accessor to PWireWidth parameter.
Modify the clone method.
* New: In CRL::RoutingLayerGauge, add new parameter "PWireWidth"
to give the width of a wire when it not drawn in the prefered
routing direction. If it is set to zero, the normal width is
used.
* New: In CRL::PyRoutingGauge, export the updated constructor
interface. It is *not* backward compatible, one must add the
PWireWidth parameter in the various kite.py configuration
files (in etc/).
* Change: In AnabaticEngine::_gutAnabatic(), disable the minimum
area detection mechanism, replaced by a more complete one in
Katana::Track. Left commented out for now, but will be removed
in the future.
* Change: In Anabatic::AutoContact::updateLayer(), now systematically
calls setLayerAndWidth() to potentially resize the VIAs. This is
needed in real mode as VIAs are *not* macro-generated but have
their real final size.
* Change: In Anabatic::AutoContact::setLayerAndWidth(), select the
width and height of the contact using the gauge wire width *and*
perpandicular *wire width*.
* Change: In Anabatic::AutoSegment::_initialize(), the "VIA to same cap"
to PWireWidth/2, this will be the size of the VIA in the
non-preferred direction at the end cap (non-square in real mode).
* Change: In Anabatic::AutoSegment::getExtensionCap(), makes different
cases for symbolic and real. Use raw length in real, add half the
wire width in symbolic.
Add a flag to get the extension cap *only*, not increased of
half the minimal spacing.
* Change: In Anabatic::AutoSegment::bloatStackedStrap(), enhanced,
but finally unused...
* New: In Anabatic::AutoSegment::create(), use the PWireWidth when
the segment is not in the preferred routing direction (and of
minimal width).
* New: In Anabatic::Configuration, add new getPWirewidth(),
DPHorizontalWidth() and DPVerticalWidth() accessors.
* Change: In AnabaticEngine::setupPreRouteds(), skip components in
in "cut" material. We are only interested in objects containing
some metal (happens in real mode when VIAs cuts are really there).
* New: In Katana::PowerRailsPlanes::Rail::doLayout(), add an hard-coded
patch that artificially enlarge the *wide wire* so the spacing for
wide wire is enforced. For now, two pitches on each side for
"FlexLib" gauge.
* New: In Katana::Track, add support to find and correct small wire
chunks so they respect the minimum area rules.
Two helper functions:
* ::hasSameLayerTurn(), to find if a a TrackElement as non-zero length
perpandicular is same layer connected to it.
* ::toFoundryGrid(), to ensure that all coordinates will be on the
foundry grid (may move in a more shared location).
* ::expandToMinArea(), try to expand, *in the routing direction*
the too small wire so it respect the minimal area. Check for the
free space in the track.
Track::minExpandArea() go through all the TrackElements in the track
to look for too small ones and correct them.
* Change: In Katana::RoutingPlane, add an accessor to get the tracks.
* New: In KatanaEngine::finalizeLayout(), add a post-treatment to find
for minimal area violations.
* Change: In cumulus/plugins.block.configuration.GaugeConf, add a
routingBb attribute that will serve as a common reference to all
the functions calculation track positions. We must not have two
different reference for the core and the corona. The reference
is always the corona when we working on a complete chip.
* New: In cumulus/plugins.block.configuration.GaugeConf.getTrack(),
Simplified and more reliable way of getting tracks positions.
Use the routingBb.
* New: In cumulus/plugins.block.configuration.GaugeConf.rpAccess(),
Make use of getTrack() to get every metal strap on the right
X/Y position.
* New: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(),
As those wires are left alone by the router, it is our responsability
to abide by the minimal area rule here. Hence the code duplication
from the router (bad).
Mainly wires made for the clock tree, I mean.
* Bug: In cumulus/plugins.chip.configuration.ChipConf.setupICore(),
the core instance must be placed on the GCell grid, defined by the
slice height (X *and* Y).
* Bug: In cumulus/plugins.chip.corona.Builder(), forgot to use bigvia
for the corners of the inner ring.
* Bug: In cumulus/plugins.chip.pads.corona._createCoreWire(), hard-coded
patch for LibreSOCIO, the power/ground connectors toward the core
are too wide and can create DRC errors when put side by side.
Shrink them by the minimal distance.
* New: In Hurricane::NetRoutingProperty, add and change the meaning
of the following flags:
- ManualGlobalRoute : now means that a global routing *trunk*
is present, made of "gmetalh", "gmetalv" & "gcontact".
- Manualdetailroute : added, get the former meaning of
ManualGlobalRoute, that is, the detailed routing is
already present for this net, but can be changed by the
detailed router. Implies that it respect the Terminal,
HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
segments from the ripup. Change the segment sorting function
so that thoses segments are put in head of list (considered
as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
global routed and manual detail routed signals, and tag them
accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
managed by the gauge (comparison by mask).
* Change: In CRL::RoutingLayerGauge::getHorizontalGauge(), when selecting
the default gauge, try, if possible to avoid the PinOnly one.
Same goes for the vertical one.
* Bug: In Katana::TrackCost CTOR, symmetric track axis position was wrong,
was using the reference instead of the symmetric.
* Bug: In BoraEngine::updatePlacement(), set up the Dijkstra search halo
to one pitch so it can use immediately neighboring channels.
* New: In BoraEngine, added python startup hook like in Katana. Mainly
to setup debug nets.
* Bug: In cumulus/plugins/PadsCorona.py, when a pad is at the beginning
or at the end of the side, the pad corona terminal may be outside
the corona range (not directly facing it). In that case, create a
bend to reach it.
Worse, in some case more than one (but likely no more), could be
in that case, so not only do we create a bend but also make a
shift in the bended segment so two consecutive ones are not on the
same axis, causing shorts.
If both end pads of a corner are in that case, we cannot prevent
a short, so at least, issue a warning.
* Bug: In CRL::Vhdl, the Entity::VstUseConcat was not passed correctly
along, so we did get a strange mix of conat and direct assignment.
* New: In Unicorn/cgt.py : added --vst-use-concat options to control
the VST driver behavior.
* Bug: In Hurricane python module, forgot to add the Segment type.
* Change: In Isobar/layer.getEnclosure() wrapper check and cast the Layer
argument into BasicLayer.
* Change: In CRL::RoutingGauge::getLayerGauge(Layer*), getLayerType() and
getLayerDirection() no longer check layer identity based on layer
mask instead of just Layer* pointer. To allow a unified call wether
the layer is real or symbolic.
* Change: In CRL::RoutingLayerGauge::getTrackIndex() and getTrackPositon(),
no longer consider negative indexes as invalid and reset them to
zero. The check for out of bound index is now left to Anabatic &
Katana.
* Change: In CRL/RoutingGauge.getRoutingLayer() and getContactLayer(),
more detailed error message.
* Change: In CRL/RoutingLayerGauge.getTrackIndex() and getTrackPosition(),
indexes are now signed long instead of unsigned.
* Bug: In Katana::Track::expandFreeInterval(), the OutsideElement case was
not handled correctly, the end index must be increased in that case.
As a result, this function was returning too short an interval.
This was affecting the computation of perpandicular free interval
in DataNegociate::update() for perpandicular fixed but not in a track.
* New: In Anabatic::NetBuilder and NetBuilderVH, now manage GCells with
one Pin, and up to three globals. Used to put terminals at the
edge of a block.
* New: In EtesianEngine, now manage placed Pins.
(done through extractInstanceName())
* Change: In CRL::RoutingGauge::getHorizontalGauge() no longer skip PinOnly
gauges to find the reference one (same goes for vertical).
* New: In CRL, implement a true GDSII driver. The driver is directly under
CRL and do not use an intermediate structure in vlsisapd. The ASCII
GDSII is removed.
Huge polygons are not supported yet. Have to be split up in
sub-polygons of less than 4000 vertexes.
Symbolic layout can be exported to give a rough idea of the layout
but RDS expension is not applied. Symbolic composite layers are
expansed into their basic layers so the design *looks* normal.
* Deprecated: In CRL, remove all traces of the old XML configuration
parsers. No one needs them now, including Chams.
* Bug: In CRL::BlifParser, before blindly loading the model of a subckt
from disk with AllianceFramework, checks if it is in the Catalog
first. Load with AllianceFramework only cells that are in the
Catalog.
This prevent a file of the same name than a model to be loaded
shadowing the later defintion of the model in the Blif file.
All this is due to the fact that Blif could be non-ordered for
the models...
* Change: In Hurricane::BasicLayer, the "extract number" is replaced
by a GdsLayer and GdsDatatype to generate accurate GDS files.
Even if datatype is 0 most of the time.
Update all the "technology.conf" files in CRL to provide those
two numbers.
* New: In Commons, inspector support for std::pair<T,U>.
* New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non
square VIAs. The hole (cut) remains square, but the various metal
extensions can now be different in X and Y. The ::getEnclosure()
method now takes a flag EnclosureH / EnclosureV.
* New: In Hurricane::DbU, inspector support for:
std::pair<DbU::Unit,DbU::Unit>
std::array<DbU::Unit,3>
Must be defined here as DbU do not exists yet in Commons.h
* Bug: In Hurricane::Interval::getSize(), when the interval is "full span",
do not return the difference between min and max, but directly DbU::Max.
(the previous result was -1 !)
* New: In CRL Core Python/Technology.py, support for non square VIAs in
the configuration files. Applied to FreePDK 45.
* New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge
is for symbolic layout or not. Exported to Python.
* New: In Anabatic::AutoHorizontal::updatePosition(), differentiated
computation for soure or target taking account of the VIA extension
in the right segment metal (due to non-square VIAs).
* Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is
UP for HV gauges and DOWN for VH.
* New: In Anabatic::AutoSegment::_initialize(), create a cache of the
various extension length for each layer (viaToTop, viaToBottom,
viaToSame).
New implementation of getExtensionCap() using the previous cached
extension table. See updatePositions().
New static functions to access the extension cache in the header:
getViaTotopCap() ...
* Change: In Anabatic::AutoSegment, in various update methods, updateOrient()
must always be called *before* updatePositions() as extensions are
dependant on source/target.
* New: In Anabatic::AutoSegment::getEndAxes() compute the position of the
first source and last target position (center/axes) on an *aligned*
set of segments.
* New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to
signal segments that can be put on only one track. Specific case
to VH gauge for a M1 vertical terminal with a M2 vertical segment.
The M2 is effectively bound to the M1 axis position.
* Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global
and only one RoutingPad the connexion to the RoutingPad was duplicated.
It was valid, but totally stupid.
* Bug: In Anabatic::Session::_canonize(), for an aligned segment set,
intersect the user constraints from all segments instead of only
considering the canonical one.
Issue a warning about too tight constraints only for symbolic
gauges. It may be correct for the real ones.
* New: In Katata::DataNegociate::update(), more accurate computation
of the perpandicular free interval. Use segment extension cap
calculation. Create a special case for fixed axis segments allowing
them to find alternative free interval, try under source and under
target as they are likely to be draggable segments.
* Change: In Katana::Manipulator::relax(), use the extension cap value
to compute the axis of the perpandicular segemnts.
* Change: In Katana::Manipulator::moveUp(), now move up the whole set
of aligned segments instead of just the canonical one.
* Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate
TrackMarkers insertions for fixed terminals.
* New: In Katana::RoutingEvent::Key::Compare::operator(), segments with
fixed axis are processed prior to any others.
* New: In Katana::RoutingEventLoop, store segment pointers instead of
ids to generate more accurate error messages.
* Change: In Katana::RoutingPlane::create(), perform local track
assignment only for HV gauges.
* Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize"
step in the automaton. Mutliple states transitions can occurs in
a row if an action fails.
* New: In Katana::Session::_toIntervalAxis(), normalize interval
bounds so they are on track positions (by shrinking the interval).
* Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.
* Change: In Hurricane::Technology, in all the layer connexity methods
(getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
the "useWorking" parameter is replaced by a more accurate "useSymbolic".
BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
none was found, NULL was returned. Now, if the symbolic layer is not
found, we try to return the associated real one (same layer mask,
but not flagged as symbolic, and usually with a lowercase name).
All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
"isWorking" attribute into "isSymbolic" (to match the technology
renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
rename the tables describing the technology as follow:
- symbolicLayersTable --> compositeLayersTable
- workingLayersTable --> symbolicLayersTable
- symbolicRulesTable --> layersExtensionsTable
This is to give the table names a more clearer semantic after
merging real technologies configurations (testbench AMS c35b4).
In particular, we need to define a composite layer for the
real VIAs, and not only the symbolic ones. And with correct
enclosures expressed in real dimensions (microns).
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
flags to request the loading of a "foreign" cell. That is, a Cell which
is *not* in the Alliance libraries, but in *any* library starting from
the root library. This is a temporary hack to allow the Blif parser to
run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
RoutingGauge::getVerticalGauge() to avoid relying on either metal names
or depth to know the vertical and horizontal default routing
informations. They return the metal layers gauges *closests* to the
substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
"etesian.cell.zero" & "etesian.cell.one" to figure out what are the
tielow and tiehigh cells (instead of having the ones from sxlib
hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
the lowest vertical and horizontal pitches are not equal. Needs to
work with two pitches (H & V) instead of one.
The Configuration associated class now also provides the
RoutingGauge (not only the CellGauge).
Use a new Configuration setting "etesian.feedNames" to set up
the names of the filler cells. This a string of comma separated
cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
non-square grid scheme.
* New: In CRL Core, in RoutingLayerGauge, adds a new parameter "obstacleDw".
It represents the distance to add from the *edge* of a blockage segment
to the next *axis* of a routing track. This was previously computed as
the pitch minus the mimimum half wire width. This works if the pitch
is *equal* to the wire width plus the minimal distance (edge to edge).
But if the wire width is less, than it leads to too great a distance
around obstacles, making them bigger than they are. And potentially
blocking everything. To summarize:
before: obstacleDw = pitch - wireWidth/2 (deduced)
after: obstacleDw = explicitly setup, usually:
pitch - max(wireWidth)/2
Modify the Alliance configuration helper and the various kite.conf
file accordingly.
* New: In Kite, in BuildPowerRails, make use of "obstacleDw" to compute
the footprint of a blockage.
* Test: post-receive hook on server should send mail [1].
* New: In VLSISAPD, in Parameter, callback have now a tag, which the
pointer to the caller. This allow for the callback removal when
the caller is destroyed.
* New: In VLSISAPD, in WidgetDescription, when associated to a parameter,
the destructor must remove the associated callback function on
the Parameter.
* New: In Hurricane, added JSON support for Configuration, separated
from vlsisapd, as the support is not available at this point.
JSON support for Configuration, Parameter & LayoutDescription.
* Change: In Hurricane, in JsonStack, the stack of JsonObjects has been
displaced here from HurricaneHandler. This way, all
JsonObject::toData() can access the JsonOjects in the context
of the parser.
* New: In Hurricane, in DBo::toJson() added support for Entity by
reference (ids).
* New: In Hurricane, added JSON support for all Layer sub-class types.
* New: In Hurricane, in Technology, export the Layers, but must be
sorted by increasing mask value.
* New: In Hurricane, in Entity, added support for Entity by reference (ids).
* New: In Hurricane, in DataBase, added technology full support.
* New: In Hurricane, In JsonNet, move the ring rebuild management from
JsonStack to JsonNet.
* New: In Hurricane, added JSON support for NetAlias, NetExternalcomponents
(not cleanly implemented as a Relation).
* New: In Hurricane, new method Cell::fromJson() to load a cell from
a JSON file.
* New: In Hurricane, In Graphics, make it an observable, for when JSON
fully reload the graphic state, it must be able to notify other
objects (namely the Controller).
* New: In Hurricane, in ControllerWidget, observe the Graphics to regenerate
the palette as needed. New method ControllerTab::graphicsUpdated().
* New: In Hurricane, in RawDrawingStyle added a destructor to release the
Qt pen/brush. Added JSON support for HSVr, DrawingStyle, DrawingGroup,
& DisplayStyle.
* New: In Hurricane, in GraphicsWidget, rewrite correctly the readGraphics()
to erase the previous widgets and re-create the new ones.
* New: In Hurricane, in PaletteWidget, correct re-creation of the layout/widgets
in case of Graphics change.
* New: In CRL Core, in System, register the parameters callbacks with
the address of the object, for later deletion.
* New: In CRL Core, in AllianceFramework, make it observable, to notify
library changes. For the AllianceFramework creation, now allow to
completly bypass the Python initialization system, when we expect
to restore it from a full blob. Added methods to sets the default
RoutingGauge & CellGauge.
* New: In CRL Core, added JSON suppport for CellGauge, RoutingLayerGauge
& RoutingGauge.
* New: In CRL Core, in LibraryManager, oberver AllianceFramework, to update
the list of libraries in case of change (for JSON full reload).
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
vertexes in the grid (must not be used by the global router).
Modificate the Graph::getVertex() method so that when a vertex
is geometrically queried, if is a blocked one, return a non-blocked
neighbor. This mechanism is introduced to, at last, prevent the
global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
A reduced segment is in the same layer as it's perpandiculars.
To be reduced, a segments has to be connected on source & target to
AutoContactTurn, both of the perpandiculars must be of the same layer
(below or above) and it's length must not exceed one pitch in the
perpandicular direction.
To reduce an AutoSegment, call ::reduce() and to revert the state,
call ::raise(). Two associated predicates are associated:
::canReduce() and ::mustRaise().
Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
to connect to the pads. Create wiring, fixed and non managed by
Katabatic, to connect the pad connector layer to the lowest routing
layers (depth 1 & 2). The former implementation was sometimes leading
to gaps (sheared contact) that *must not* occurs during the building
stage.
Remark: This bug did put under the light the fact that the initial
wiring must be created without gaps. Gaps are closed by making doglegs
on contacts. But this mechanism could only work when the database if
fully initialised (the cache is up to date). Otherwise various problems
arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
when anchored on a RoutingPad, now take account the potential rotation
of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
to reduced AutoSegment are *not* inserted into track to become
effectively invisibles. When a segment becomes reduced, a TrackEvent
is generated to remove it. Conversely when it is raised a RoutingEvent
is created/rescheduled to insert it. All this is mostly managed inside
the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
Y coordinate of the chip size. Did not show until a non-square chip
was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
backward compatibility with the MIPS32 bench. Have to review this
functionnality coming from the deprecated placeAndroute.py.
In st_instance.py, no longer creates the Plug ring of a Net.
In my opinion it just clutter the display until the P&R is called.
Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py .
Miscellaneous:
* Change: In <crlcore>, in display.conf use the same display threshold
for both METAL2 & METAL3.
In alliance.conf, the side of VIAs in the gauge is 2l (not 3l).
In kite.conf, separate edge densities for H/V.
* Change: In <Cell>, in flattenNets() use flag as argument, not a
boolean. Do not create rings for clock or supply nets.
* Change: In <DeepNet>, in _createRoutingPads() do not create rings
for clock or supply net (duplicated policy as in Cell::flattenNets()).
* Bug: In <ControllerWidget>, at last find the bad signal disconnect
that was causing ungraceful messages.
* Change: In <knik>, in Edge display occupancy/capacity in the string
name. Improved display progress and debugging capabilities.
Improved exception catch & breakpoint managment:
* Bug: In <PaletteWidget>, in updateExtensions() replace the calls to
deleteLayer() by delete. This cause the widget to be immediatly
erased instead of waiting for the event queue to be completly
processed. This was causing the widget to be left in a incoherent
state when stoping at a breakpoint.
* Bug: In <BreakpointWidget>, in execNoModal(), flush the main event
loop (QApplication::flush()) *before* lauching the *local* event
loop. This is to ensure all widgets are in their final state when
waiting (especially <PaletteWidget>).
* Change: In <ExceptionWidget>, new method catchAllWrapper() to
execute any std::function< void() > function/method with a "try"/
"catch" wraparound and lauch the widget in case something is catch.
* New: In <hurricane>, support for a oberver pattern, backported from
<katabatic> with an Obervable capable of being linked to any
number of Obervers.
* New: In <Cell>, made it observable to detect Cell change, currently
emit two kind of signals:
- Cell::CellAboutToChange : *before* any change.
- Cell::CellChanged : *after* the change has been completed.
* New: In <UpdateSession>, in Go::invalidate() add the Cell owning the
Go to the UPDATOR_STACK (of course the cell is added only once).
In addition, when the Cell is added, send a notification of
Cell::CellAboutToChange to all it's observers. The slave instances
are also invalidated.
Conversely in UpdateSession::_preDestroy() for each invalidated
Cell send a Cell::CellChanged notification to all observer.
The UPDATOR_STACK has been slightly amended to accept Cell which
are not Gos. Prior to this, the Cell where completly excluded from
the UpdateSession mechanism, so it's instances where never actualised
of anything referring to the Cell for that matter.
Note: we use two different mechanisms to transmit a Cell change,
observers and the slave instance map. I think at some point it
should be unificated.
* Change: In <CellViewer>, make it a Cell observer to redraw when the
cell is modificated (also update the palette).
Uses the catchAllWrapper() to protect all critical actions.
* Change: In <GraphicTool>, no longer need of cellPreModificated and
cellPostModificated signals. Now done through the Cell obersvers.
* Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper
method for protection (need to split methods in two, to be able
to pass it as argument). No longer emit cellPreModificated and
cellPostModificated.
Support for RoutingGauge in P&R:
* Bug: In <placeandroute.py>, the connection from the internal power
ring to the connectors was not done correctly. Wrong contact layers
leading to a gap.
* Change: In <BuildPowerRails>, detection of the corona signals based
on how the "pck_px" pad is connected. No longer based on name
matching.
* Change: In <placeandroute.py>, support for 2 routing metal only
(3 metal in the technology).
* Change: In <katabatic> & <kite> support for a "top layer" limitation
on the routing gauge, this allows to use only two routing metals
(METAL2 & METAL3). Work in progress.
