* Bug: In Track::repair(), consider the blockage net as any other, so
the metal filling works correctly (correct management of transitions
between blockage and non-blockage).
* Change: In Katana::PowerRails, in TerminalNetlist cells instances,
the ordinary nets components where generating obstacles, leading
to stupid cross blockages between the obstacle generated by the
component supporting the routing pad and the RP itself.
Now only take into account supplies and clocks (any layers)
and blockage layers.
Fix symbolic benches.
* Change: In Katana::Manipulator::moveUp(), the "reserve" value was
of 0.5 for pivot up and locals, now set it to 1.0, like in all
other cases ("reserve" is the number of free tracks that is
needed to allow the move up, in addition the the length being
moved up).
Fix routing convergence on the MIPS pipeline bench.
* Bug: In Track::repair(), when a same net gap has been found and closed,
we display a warning. We display the two segments fused, but when it's
the two first, we must not use index "i-1" (with i=0) ...
* Bug: In Katana::GlobalNetTable::getRootNet(), look for all fixed nets,
not only supplies and clocks. There may be some as now H-Trees are
not limited to clocks.
Should solve ao68000 short circuit cases.
* Change: In Track::addOverlapCost(), in some configuration, we can
have two overlapping short segments that can *both* be realigned.
But they prevent that because we account their shared length on
the track.
So now, in realign mode only, do not account same-net shared
length if the segment length is less than *two perpandicular pitches*.
This helps the antenna protection by making the diode connected
directly to METAL2 long stripes, and not keeping them isolated.
* Change: In Katana::Track::addOverlapCost(), if an overlaping segment
is owned by the net *and* is the one we want to insert, do not take
it into account in the shared length.
This case never occured before we introduced the "realign" stage,
as a to be inserted segment, was, by definition, not already
inserted in a track. But in the realign stage, it is. So we should
not account it when computing the insertion cost in the track it
is already in. This was preventing short segments (less than a
pitch) to be correctly re-aligned.
And, as a side effect, preventing the antenna/diodes to work as
intended (diode connected at METAL3 layer while the antenna occur
at METAL2 layer).
* Change: In SegmentFsm::_slackenLocal(), in the Minimize state, when
the segment is fully blocked *and* has *lot* of candidate tracks,
that means that it is up against a *massive* blockage (i.e. a macro
block). In that case, try to move up (to go *over* it).
Previous behavior was to go straight to Inimplemented state.
* Change: In SegmentFsm::_slackenGlobal(), manage fully blocked
global segments. But finally, this configuration didn't arise.
* Change: In Manipulator::moveUp(), restore the management of the
AllowLocalMoveUp flag, to be able to move up local segments
(needed by SegmentFsm::_slackenLocal()).
* New: In Track::repair(), the gapset was used to *close* same-net gaps
is now alos used to restore minimal spacing between different nets.
Seems to be not fully working yet.
* In KatanaEngine:
- Former situation:
Each RoutingEvent did store the routing stage it was in. And it
was misnamed "mode".
- New organization:
The routing stage is stored in KatanaEngine itself. It can be
accessed through a proxy in Session.
* Change: In DataNegociate::update(), when in Realign stage and computing
non-preferred perpnadicular routing *do not* expand of one pitch
outside the RoutingPad range.
* Bug: In TrackSegment::getFreeInterval(), if, for whatever reason,
a discrepency happens between the TrackSegment and the Track,
that is the _track fields point to a *wrong* Track. Then the
index lookup will fail (Track::npos), so return an all-span
interval instead of trying to expand it and crash (out of
bound).
* New: In Track::repair(), short gaps between segments of the same
nets where occuring and being not detected. This was causing
DRC minimal distance violations. Now, fuse the segments when
they are too close. Done by extenting the duSource of the
rightmost one to the leftlost one.
Create ancillary class GapSet to manage the gaps of the
various segment of the same net.
When a segment is placed only once (which is to say it is nerver ripped
up) it can sometimes end-up in a non-optimal place. We now add a stage
in Katana where each segment is "re-placed" in order to maximise
alignment on it's neighbor. This is a new stage added to both
RoutingEvent and NegociateWidow. Segments are replaced *only* in free
space, they will not ripup *other* segments, except for their own
perpandiculars. We exclude from re-placement globals (unlikely to move)
and segment that have reduced perpandiculars which *must* not be elongated
and potentially raised.
Add a new katana setting to enable/disable the realign stage (enabled
by default:
- "katana.runRealignStage" ( = True )
We use the segments extensions (dxTarget & dyTarget) to enlarge if
needed the segments. This new implementation is completely at
Anabatic level and should not be seen (i.e. managed) at Katana level.
* Change: In AutoHorizontal & AutoVertical, change the semantic of
getSourceU() and getTargetU(). formerly they where the end
position of the segment (with extension included), now they
gives the position of the anchor contacts, that is the axis
of the perpandiculars.
* New: AutoSegment::getLength() is still a proxy toward the
Segment::getLength() which returns the length of segment with
dxSource & dxTarget. We introduce a getAnchoredlength()
which returns the length between the centers of the S/T
anchors. That is axis to axis.
This is this length which is now used througout Anabatic.
* New: In AutoSegment::_extentionCaps, add a fourth item to hold
the segment minimal length (to respect minimal area given
the wire width).
* New: In AutoSegment::getExtensionCap(), if the segment has
a non-zero S/T extension, returns it instead of the S/T
contact extension *if it is greated*. The check of the
extension can be disabled by the Flag::NoSegExt flag.
* Change: In AutoSegment::isMiddleStack(), security check on
the presence of source and targets. More accurate detection
of perpandicular in "same layer" with a non-zero length,
So the area is OK, even with a short segment.
* New: AutoSegment::expandToMinLength(), check if a segment is
under the minimal length and expand it if need be by playing
with the dxTarget & dxSource. Tag minimal segments with the
AutoSegment::SegAtMinArea flag. Also try to keep the segment
*inside* it's former (supposedly wider) interval.
* New: AutoSegment::unexpandToMinLength(), to be called on a
formerly minimal sized segment which as grown up. Reset
it's S/T extensions to zero and unset the flag SegAtMinArea.
* Change: In AutoHorizontal::updateOrient(), when the extension
are non-zero, also swap them if needed, to keep the exact
footprint of the segment.
* New: In AutoSegment::revalidate(), check that the segment
respect the minimal length (area), and expand it if needed.
Conversely, if the segment has grown up from a minimal
length state, reset it's extensions to zero.
* Change: In Anabatic::Session::revalidate(), invalidateds
segments are now sorted in such a way that the "middle stack"
ones are revalidateds last. Not recall 100% why...
* New: In Katana::TrackCost, add a computation of the free interval
length we are into (if any). Not used yet, keep it for future
use.
* Change: In KatanaEngine::finalizeLayout(), remove the call to
segments minimum area protection. It is now obsoleted by the
new implementation in Anabatic.
* Change: In Track::check(), call the minimum size/area checker
Track::checkMinArea().
* Change: In NetBuilder::getPositions(), ordering of source/target points
is now integrated to this function instead of left to the caller.
In case of real (non-symbolic) routing gauge, skrink the ends of
half the wire width.
* Change: In NetBuilderHV::doRp_AutoContacts(), in case of non-METAL1
RoutingPad, put the axis of the segment on the nearest track.
Issue a warning if we have to shift, as it may be a potential
source of routing problems.
* New: Anabatic::Session::getNearestTrackaAxis(), proxy to compute
track positions, knowing the design abutment box.
* Bug: In Katana::PreProcess::propagateCagedConstraints(), when
looking at all the slave components anchoreds on a RoutingPad,
if they do not have an AutoSegment lookup, skip them instead
of crashing.
* New: In cumulus/plugins.block.Block.placeMacro(), new method to
place a macro cell, partly delegating to the Macro block wrapper.
Must be called *after* both core and corona abutment boxes have
been set.
Adjust the macro block position so the METAL2 & METAL3 pins
are exactly on pitch regarding the full routing grid. The reference
being the corona.
A shift, less than one pitch may be applied, leading in some
cases of overlapping abutment boxes. But this shouldn't be a
problem.
The macro to place is designated through a path of instances
names, rooted at the *core* (not the corona). Meaning that the
head instance must be one of the core.
* Change: In cumulus/plugins.chip.Chip, the complete chip I/O pads
plus corona and core placement is moved out from doPnR() and
put into doChipFloorplan(). It is now mandatory to call this
method *before* doPnR().
Those methods are now cleanly separated so we can perform macro
block placement or any inner core floorplaning operations between
them.
* Change: In cumulus/plugins.macro.Macro, instead of creating large
pads for the I/O pins so whatever the block position, they will
be under a grid point, create a simple dogleg to put them on
grid.
To ensure that they are "on grid", the block pins must be
in METAL2 (horizontal E/W) or METAL3 (vertical N/S) and the block
is assumed to be placed so the bottom left corner of it's
abutment box is exactly on one grid point for M2/M3.
This should be done by Block.placeMacro().
* Bug: In PowerRailsPlanes::Rail::doLayout(), in case of non-blockage but
fixed segments (that is, power lines), expand the segment box of one
picth to put blockage on too close neigboring tracks.
* Change: In Manipulator::avoidBlockage(), more accurate computation of
the blocked area for pushing aside the terminal & turn of the non-pref
segment.
NOTE: To myself, one more bug uncovered in the Track segments management.
This is really too complex, must find time to re-think and simplify
the whole thing.
* New: In Katana::NegociateWidow::createTrackSegment(), detect offgrid
fixed segments and insert them into tracks directly (as *wide* segment
of two tracks).
* New: In Katana::TrackSegment::create() factory method, check for offgrid
fixed segment and use a TrackSegmentWide (of 2 tracks) for them.
* New: In Katana::TrackSegmentWide CTOR, check if they are used in the
context of an offgrid segment and in that case set the track span
to two. We *do not* manage yet the case for both *wide* and *offgrid*
segments.
* Change: In Katana::PowerRails::Rails::doLayout(), do not expand blockage
rectangles over their real size. Add the guard only for real layers
segments.
* Bug: In Katana::PreProcess::propagateCagedConstraints(), when looking
for the first track index, check for out of bound value (npos).
* Bug: In Katana::Track::addOverlapCost(), before using the overlap
segment indexes, check if we are not in a free hole (get the free
interval from center).
* Bug: In Katana::Track::expandFreeInterval(), the interval was badly
computed if it was included inside segments of another (same) net.
under the fixed segment, we were using the axis *of the segment*,
but if it is very wide, this is completly off.
Now use the axis of the *track* to get the right GCells impacteds.
* Bug: In KatanaEngine::annotateGlobalGraph(), overlapping blockages or
fixed segments where taken into account as separate ones. This was
making the edge capacity reservation too high. Creating false
zero-capacity edges at some points.
Didn't show up until now because we did not have overlaps.
* 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).
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.
* Bug: In Anabatic::AutoSegment::reduce(), no longer reduce *again*
an already reduced segment.
This bug was seen through a side effect, it was causing the
"reduced perpandicular" counter to be incremented too much and
so it cannot get back to zero, blocking the layer reduction
(AutoSegment::reduceDoglegLayer()) and some bad VIAs where left
over.
More debug information in reduce & raise functions.
* Change: In Katana::Session::_revalidate(), process to be raised
segments *before* segments that can be reduceds.
Note: To implement this in a more flexible way we should introduce a
concept of Instance/Cell "placeholder" to reserve space
transhierarchically.
* Change: In EtesianEngine::toColoquinte(), when placing only one block
in a cell, the cell itself can contains other fixed instances
that are over the placement area. Create dummy fixed instances
to reserve the taken space.
In EtesianEngine::AddFeeds(), do not put feed cells over the
cell area occuped by the sibling instances cells.
* Cleanup: In KatanaEngine::setupPowerRails(): small cleanup.
* 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).
* New: In flute, added a Python binding. Contains two methods: "readLUT()",
to load the POWV9.dat and POST9.dat and "flute()" to build a RSMT.
"flute()" takes a tuple of positions (themselves 2-uple) like:
( (x0,y0), (x1,y1,), ... (xN,yM) )
and returns a tuple of 3-uple of branches:
( (n0,x0,y0), (n1,x1,y1), ... )
In "flute.h", set the distance type (DTYPE) to int64_t to always
accomodate DbU::Unit.
As it now uses the Hurricane Python interface and the path utilities
from CRL Core, move it's compilation *after* them (see build.conf in
bootstrap).
* New: In Katana::Manipulator::moveUp(), if the length of the wire is
greater than 60 pitchs, increase the reserve from 0.5 track to
1.0 track. This is to left more free tracks when lots of very
long segments are moved up. Make the run 17 of the ARM test bench
pass.
* New: In Katana::Configuration, two new parameters hTrackReservedMin
and same for V. Forced decrease of all edges capacities, to use
when the global router is too optimistic...
* Bug: In Hurricane/Commons.h, modify the getRecord<>() templates so
that for both vector<Element> and vector<Element*>, the individual
record created for each element are donne with pointers. That is,
for the vector<Element> case, we take a pointer.
As a general policy, except for the POD types, always use pointers
or references to data in the records/inspector. Never uses values
that can call the copy constructor.
Suppress INSPECTOR_PV_SUPPORT() macro, keep only
INSPECTOR_PR_SUPPORT().
Provide value support only for getString<>() template.
This value & copy constructor problem was causing a crash when
trying to inspect Hurricane::AnalogCellExtension.
* New: In Hurricane::Technology, change the API of the PhysicalRule,
now we can only create/get PhysicalRule, but setting the value of
the rule itself must be done on the rule.
Enhance PhysicalRule to provide for stepped rules, non isotropic
and ratio rules.
Merge TwoLayersPhysicalrule in PhysicalRule, much simpler to
suppress the management of derived classes. That means that we
loose a little memory as some fields are mutually exclusive.
Not a problem considering that there will not be so many of thoses
objects.
* New: In CRL/helpers.analogtechno.py, enhanced DTR support for rules
like:
('minSpacing' , 'metal1', ((0.4,20.0), (0.8,1000.0)), Length, 'REF.1')
('minEnclosure', 'metal1', 'cut1', (0.2,0.3) , Length, 'REF.2')
('minDensity' , 'metal1', 0.30 , Unit , 'REF.3')
The DTR parser has been updated, but not the oroshi.dtr Rule
cache for analog components. Given a rule name, the value used
will be the horizontal one of the first step.
* Change: In hurricane/doc/hurricane, re-generate the documentation
with updated support for Technology & PhysicalRule.
* Bug: In EtesianEngine::place(), reset the placement *only* if we are
*not* placing a sub-block *and* the top cell abutment box is empty.
* Bug: In EtesianEngine::place(), set the instance placement status of
all intermediate instances to PLACED, so the AP driver will save
them (we were having partially saved layout when using hierarchical
designs).
* Bug: In EtesianEngine::resetPlacement(), reset the PLACED flag and
the abutment box on the top cell or sub-block to be placed.
* 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).
* Bug: In Katana::NegociateWindow::createTrackSegment(), *fixed* AutoSegment
in conflict with blockage where removeds. This was creating "holes"
in the Anabatic articulated segment structure. Now just *don't*
create the TrackSegment. Pass the regression tests, but not sure
it is not generating problems elsewhere.
* New: AnabaticEngine::checkPlacement() to issue more clear errors about
a defective placement.
* New: In Anabatic::NetBuilderHV(), added configurations to manage
one Pin M3 + one M1 terminal plus 2 & 3 globals:
* _do_2G_1M1_1PinM3()
* _do_3G_1M1_1PinM3()
They were occuring for the first time in soclayout/experiment7
in the "flat" approach.
* New: In Katana::runNegociate(), mark the newly routed netlist as
"NetlistTerminal" so it is not placed and routed *again* when
reused as an instance (mostly interract with Etesian).
* Bug: In CRL::VstParserGrammar & VstParserScanner, when loading the
instances models, we where loading both logical & physical views.
This was causing cases of reentrency of the parser, with reset
of the lexer static dictionary, leading to memory corruption.
Now the identifiers are stored in the YaccState of each
parsed cell and we only recursively call for the logical view.
* Change: In CRL::ApParser::_parseInstance(), recursively load the
physical views as they are no longer loaded by the Vst parser.
* Change: In CRL::AllianceFramework::getCell(), sets the
TerminalNetlist flag from the state (mode 'C' in CATAL) onto
the cell.
* Change: In EtesianEngine::loadLeafcelllayouts(), new functions to
load the layouts of the leaf cells if only the netlist has been
loaded.
