* Bug: In CRL::GdsParser, the PLL was using copies of the standard cell
with the same name. And unfortunately, they where found *before*
the FlexLib one when using DataBase::getCell(). As their I/O where
wrong it was leading to a massive netlist connexion corruption in
blif2vst.
To avoid that, any Cell created by the GDS parser is now prefixed
by "gds_".
* Change: In CRL::GdsStream CTOR, report when the file cannot be opened
instead of saying that the GDS file is corrupted (misleading).
* Bug: In Vhdl::VhdlPortmap::toVhdlPortMap(), when the mapped names
are part of a vector, but *not* in the "downto" direction,
unvectorize anyway. In the component declarations, vectors are
always in "downto" order, so they must also be mapped in that
order.
* Bug: In CRL::BlifParser::newOne() & newZero(), we have to create
signal names different from instance names for VHDL compliance.
This is complementary to what is done in blif2vst.
No completely satisfied with that. Should find a more generic
way to do it in the future.
* Change: In Hurricane::NetAlias, store additional data in NetAliasName,
the external status of the former Net. When a Net::merge() is
performed, we must keep track of whether the merged (destroyed)
one was external and keep that information.
Add NetAliasHook::isExternal() & NetAliasHook::setExternal()
virtual methods.
* Change: In Net::getNet() add a new optional argument to allow the
search of the net name in *internal* aliases. Otherwise only the
aliases tagged as *external* will be searched.
It was a bug that, when looking for a Plug master net by name
we got an homonymous internal net. In that case we must only
look for net that are (or where) part of the interface.
* New: In Vhdl::VectorSignal, when a vector contains only one bit,
unvectorize it, like when it is non-contiguous (we use the
isCountiguous() method to carry that information).
* New: In Vhdl::VhdlEntity, Catalog::State and NamingScheme, added
a flag UniquifyUpperCase to uniquify the names in uppercases.
In case of a clash with the same name in lowercase.
Prepend 'u' before all previously uppercased letter. For
example 'VexRiscV' becomes 'uvexuriscuv' (urgh!).
The Catalog flags is exported to Python for use by the blif2vst
script.
* Change: In BlifParser, Model::newOne() and Model::newZero(), return
a new gate each time it is called instead of making just one for
each Model. This way, if two outside nets are connected to one
or zero they do not get merged (should work, but will be less
clear).
* Bug: In BlifParser, Model::connectSubckts(), when looking for the
master net in the instances models (by name), limit the search
to the *external* aliases names.
* Change: In NamingScheme::vlogTovhdl(), reactivate the removal of
two consecutive '_'.
* Change: In cumulus/bin/blif2vst.py, prefix the master cells
(i.e. components) with 'cmpt_' to avoid clash names with signals
in VHDL.
* Change: In CRL::GdsStream::operator<<(Cell*), external components needs
to be exported twice. First as "METALx.pin" to signal an external
component (and give it's name). And second as a "normal" component
in "METALx". If the METALx part is forgotten, the "Vendor" StreamIn
will not see the METALx.pin as something physical so f***g gaps appears
in the wiring. And furthermore, if the TEXT label is above it, the
name of the net goes away...
* New: CRL::SubNetNames (in ToolBox), takes a VHDL signal name, vectorized
or not and allow to generated sub-net names from it, with respect to
the original vector name.
Examples:
* machin -> machin_hfns_0, machin_hfns_1, ...
* bidule(3) -> bidule_bit3_hfns_0, bidule_bit3_hfns_1, ...
Makes use of the POSIX regex library to avoid Boost dependencies.
* New: CRL::restoreNetsdirection() (in ToolBox) that checks the coherency
of all Nets direction through a complete hierarchy of cells.
Stops at Cells flagged "TerminalNetlist".
Directions are rebuilt for all the Cells part of the hierarchy
in a bottom up fashion. It is also checked that Nets have only one
driver (we assume there is no three-state busses).
To sort cells in hierarchical order (bottom up according to their
depth), copy the DepthOrder class from the GDSII driver. Will unify
them later.
exported to the Python interface.
* New: In cumulus/tools/blif2vst.py, add a call to restoreNetsdirection()
before saving.
* 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.
* Change: In Model::connectSubckts(), when trying to lookup the
Hurricane Net from it's Blif name, try first as a VHDL one then
after a Verilog to VHDL translation. Especially useful for bits
of vectorized names ("signal[X]" --> "signal(X)").
The policy about how to create slots was not completly clear.
Now, only add *pointers* or *references* to class attributes,
never do a "copy by value". Reflect that change in SlotTemplate<>
various partial specializations.
Hammer in your head that in C++ functions templates do not allow
for partial specialization. So write only *one* template for
::getSlot<>() (refdefinition simply got ignoreds, at least with gcc).
* Bug: In Slot, only one template for getSlot<> (see above).
Adjust SlotTemplates<> to provides partial specialization only for:
* "const Data&".
* "Data*".
* "const Data*".
* "Data* const"
* "Record*".
* Bug: In Instance::_getRecord(), suppress slot based on transient
values "XCenter" & "YCenter".
* Bug: In CRL::ToolEngine::_getRecord(), suppress slot "Name" based
on a transient value.
* Change: In ::getRecord(std::list<Elementt>*) (and variant), pass
all elements to ::getSlot() as (const Element*).
* In CRL::GdsStream::operator<<(Cell*), when encountering an *external*
component, try to find a ".pin" layer associated (if not already
in it). Then drive the BOUNDARY & TEXT in it. This way, Cadence/
Calibre seems to be able to recognize them as Pin.
* New: In CRL::GdsDriver, create TEXT record under each external
Net component. Seems to be the aknoweledged way to signal
external pins.
* New: In CRL::GdsParser, read TEXT record and create Net and
external components that are in the same layer and at the
same position.
* New: In CRL/hepers, new function onFGrid() to ensure a DbU is on the
foundry grid. Rounding is always done to the inferior integer.
* New: In CRL/GdsDriver, added a set of isOnGrid() functions to check
that all coordinates of various objects are on the foundry grid.
Use isOnGrid() in most objects processed in
GdsStream::operator<<(Cell*).
* Bug: In cumulus/plugins.chip.pads.Corner, correctly round the
coordinates of the 45 degree segments so they are still on the
foundry grid.
* New: In cumulus/plugins.core2chip.libresocio.CoreToChip, use new
configuration variable "chip.useAbstractpads" to select between the
abstract version (GPIO, VDD, ...) and the full version (IOPadInOut,
IOPadVdd, ...) layout.
* Change: In CRL::Model::staticInit(), when trying to guess the ouput
of the tie low & tie high cells check if the net name is not a
power or ground. A bad input was choosen with FlexLib as the
vdd/vss nets where not typed as POWER/GROUND.
* Change: In Hurricane::QuadTree_GosUnder::Locator::progress(), directly
prune the elements which sizes are under the threshold. This allows
the too small Instances to be directly skipped. This was the key
point slowing the walktrough. We were systematically going through
all the instances (that is consistent with the perf traces).
* Change: In Hurricane::Cell_OccurrencesUnder, add a threshold parameter
to pass on the QuadTree (through getInstancesUnder()).
Needed for the CellWidget selection to have the same problem as
the display itself (select only what is displayed).
* New: In Hurricane::CellView, add two new parameters:
1. "viewer.minimumSize" set the original size of the window, in pixels.
(doubled for HiDPI).
2. "viewer.pixelThreshold", the size, in pixels, under which
components/instances will not be displayeds.
* New: In CRL/etc/cmos.misc.py, added parameters "viewer.minimumSize"
and "viewer.pixelsThreshold".
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 CRL::GdsDriver::hasLayout(), a Cell was saved in the GDSII
stream only if it has a layout, but the check was not accurate
enough. In the Arlet6502, the whole core was missing.
Now check for the abscence of Plugs (not unfinished Nets) and
PLACED/FIXED instances.
* Change: In documentation/build.py, more PEP8 & Python 3 future compliance.
Correct copy of the tools HTML docs on my laptop, to have a full
offline copy of the doc.
* New: In documentation/contents/pages/check-toolkit, duplicate the doc
from alliance-check-toolkit README. Seems it has been inadvertently
removed at some point (?). Have to be careful to maintain in synch
with the toolkit.
* Change: <tool>/doc/*/SoC.css, use Roboto fonts when availables.
* Update: Commit the whole pre-generated docs (Doxygen, Pelican).
* Bug: In CRL/GdsStream::toGdsDbu(), when converting a physical number,
in double to a number of GDSII dbu in int32_t, we must not use the
direct cast int32_t(v) because v can be 2.9999999999 which got
simply truncated into 2 while we want 3. So now use the rounding
function std::lrint() and configure it round to the *nearest*
integer.
Note that we don't check that the long returned can correctly
fit into int32_t.
* Change: In CRL::vstDriver(), remove all Vhdl properties after running.
The properties are not updated if the cell (Entity) change, so the
next time it is called, an incomplete or incoherent state was saved
(for example, incomplete "port map"). Removing all properties is
less efficient but works.
* Cleanup: In CRL/helpers/overlay, remove forgotten debug message.
* Change: In CRL/etc/common/etesian.py, use double parameters
instead of percentages to simplify. For space margin and form
factor. This need the rewrite of coriolis2/settings.py in
alliance-check-toolkit.
* Bug: In CRL/helpers/overlay.CachedParameter.cacheRead(), values where
not read *from* the Configuration DB, due to a forgotten "self.".
In CRL/helpers/overlay.CfgCache.__setattr__(), value was simply
never set! Only interval and set of values were manageds!
In CRL/helpers/overlay.CfgCache.__getattr__(), must distinguish
between two access cases, when were are truly accessing a
CachedParameter, return it's *value*. Otherwise, it is a
recursive CfgCache, then return the object.
* New: In CRL::AllianceFramework::wrapLibrary(), can now add in the set
of AllianceLibrary one which is wrapped around another one. All the
cells must be already present and do attempt to save them with
AllianceFramework (AP parser will drive nonsensical datas).
* New: In CRL/helpers.overlay.CfgCache, create a class to fully handle
all the Configuration parameters settings. That is, range and
enumerated values. This way we can fully create them from
the CfgCache instead of merely changing the value of an
existing one.
Examples:
cfg.anabatic.gcell.displayMode = 1
cfg.anabatic.gcell.displayMode = ( ("Boundary", 1), ("Density", 2) )
cfg.katana.hTracksReservedLocal = 4
cfg.katana.hTracksReservedLocal = [ 0, 20 ]
* New: In CRL/helpers/utils.py, create a Python "class decorator".
Works like a decorator but without the need of implementing
the Concrete/Abstract classes structure Design Pattern.
Create proxies in the derived class for the base class
attributes & methods.
* Change: In cumulus/plugins/alpha/block/configuration.py, enrich
the BlockState object to support core2chip parameters. Make it
even more autonomous from the Block class.
* New: In cumulus/plugins/alpha/core2chip, port of the core2chip plugin
and integration with the alphs/block plugin. At "constant features"
as a first. Only ported "cmos", phlib will be later.
Note: Keep the various hfnsX.py as toolboxes for future experiments.
* New: cumulus/plugins/block/hfns3.py, build the trunk of the
net as a RMST. First with the "Iterative One Steiner Point"
(terribly slow above 100 points) then with FLUTE.
For the global routing trunk, must be very cautious to
check that the cluster "graph point" is the one of the
it's buffer RoutingPad so both end up in the same GCell.
* New: cumulus/plugins/block/timing.py, stub for basic
timing computation and conversion between sink and
capacitance. Currently based on the fake 350nm given as
example in SxLib ("man sxlib"...).
* 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 CRL::PyAllianceFramework, export getCatalog(), in PyCatalog,
export the getState(name) method and add a PyCatalog_Link().
In PyCatalogState, add PyCatalogState_Link(), cannot use the
macro because of the C++ name resolution operator (Catalog::State).
* New: In Isobar, export the RoutingPads collection to the Python interface.
* New: In Hurricane::Net, export the getRoutingPads() method to the
Python interface (hence the need of the previous export).
* New: Added multiple clock support in H-Tree generation in alpha/block.
* New: In CRL/etc/<NODE>/<TECH>/plugins.py, added three new parameters
for block plugin config:
"block.spareSide" : The size of the minimum side of a buffered area.
(quad-tree leaf).
"spare.buffer" : The model of the cell buffer to be used.
"spare.maxSinks" : max number of sinks on a buffer before issuing
a warning (non-blocking).
* Bug: In Etesian::BloatCell::getAb(), never apply the bloat profile to
fixed cells. In case of buffers from the spare maxtrix it was leading
Coloquinte to detect an overlap of fixed cells, which it do not
support (rightly so).
* Change: In CRL/helpers.Trace, flush stderr before issuing the trace
message to avoid mixing up stdout & stderr (sometimes misleading).
* Change: In CRL/helpers.overlay.CfgCache, no longer display all the
applied setting after a call to apply(). Too verbose.
* Change: In CRL::Environment, regex_t are now pointers instead of values,
this way the "in initialization" flag can be removed (maybe still too
complicated).
* New: In CRL/helpers.overlay.CfgCache, add support for context manager,
so we can progressively remove the use of Configuration. One class
to use in all contexts (immedaite setting or storing a set of
Cfg parameters).
* New: In CRL/helpers/overlay.py, CfgCache class to hold a set of
configuration parameters and apply it on demand. It has a
different behavior than Configuration.
* 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.
* Change: In CRL/helpers/__init__.py, to ensure a complete restart of
the database the __init__.py must be called again, but it's not the
case with reload() (see Python doc). So helpers.resetCoriolis()
must explicitly removes the Coriolis related Python modules from
sys.modules (calling "del sys.modules[moduleName]").
That list of Coriolis Python modules is built by calling
helpers.tagConfModules(), it will tag all modules added to
sys.modules since startup. It will remove (much) more than
Coriolis modules, but that should be ok.
* Change: In CRL/etc/{node*,symbolic}/TECH/__init__.py, add a call to
helpers.tagConfModules() for the techno modules to be erased on
reset.
* Bug: In CRL/Vhdl::VectorPortMap::toVhdlPortMap(), two problems:
1. Bad condition for the use of VstUseConcat. Must be used *only*
when there is more than *one* mapped name.
2. Missing case, when there is exactly *one* mapped name, that
means that we have one full width vector to vector assignement.
There may be another weakness here, for the portmap we assumes
that both vector are mapped in the *same* direction (which is
"downto" by our convention).
3. In the "bit by bit mapping case" (every bits of the vector are
differents bits), use the "signal + bit index" name instead of
juste the signal name (i.e. full width).
Solves the Libre-SOC/soclayout/experiment6/fpmul64 problem, now
we can avoid the YOSYS_FLATTEN.
* Change: In Vhdl:::Signal::toVhdlPort(), in Alliance VST signal with
undefined directions are typed "linkage". This may not be compatible
with vasy, so allow to replace them by "in".
* New: In CRL::Catalog::State, add a new flag VstNoLinkage to tell if
the VST driver should not use the "linkage" type.
* Change: In Vhdl::Entity, add a VstNoLinkage flag to disable the use
of the "linkage" type.
* New: In vlsisapd/PyConfiguration, add asDouble() to the Parameter
Python wrapper.
* New: In CRLCore/helpers/overlay, add support for float parameters
in configuratuon.
* Bug: In CRL::VectorPortmap::toVhdlPortMap(), unconnected bits where
correctly checkeds for multi-bits vectors (both ordered and holed),
but not for mono-bits connections (ONE bit of a vector).
* New: In CRL::NamingScheme, add a flag VstNoLowerCase, and its
management it in the Verilog to VHDL converter.
* Change: In CRL::BlifParser::Model::toVhdlModels(), disable the
lowercasing of identifiers. We shouldn't apply Alliance VHDL
subset constraits when reading blif files. So we will see
uppercase identifiers in Coriolis.
* Change: In CRL::VstParser, no longer lowercase identifiers that
are *not* VHDL keywords. Uppercases are legals in VHDL...
* New: In CRL::Catalog::State, add a new flag VstNoLowerCase to
tell if the VST driver should keep the uppercases.
* Change: In CRL::VhdlEntity, add a VstNolowerCase flag to disable
the lowercasing.
* Change: In CRL::vstDriver, lower case the file name if needed.
remove the previously opened filename if it differs from the
lowercased one.
* Change: In UnicornGui CTOR, disable VHDL enforcement for the
Blif parser.
* Change: In CRL::BlifParser, formerly, a zero/one cell was added for
each vss/vdd direct connection, generating a huge flock of cells.
Now only generate one per netlist.
It can be discussed whether to old behavior is more desirable,
it is a compromise between wire and area.
* Change: In CRL::AllianceFramework::getCell(), if the Cell is marked
as TerminalNetlist, then it may be a standard cell. So it's layout
must be loaded. So now, systematically try to load the layout of
netlist terminal cells.
* 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 CRL::ApParser::_parseInstance(), the instance coordinates where
stored in *static* variables (boo). Making the parser *not* reentrant.
But in _parseInstance(), it can be recursively called through
getCell() when an sub-instance layout was missing.
Also make non-static all other variables in the various parser
function.
* 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.
* Bug: In CRL::ApDriver::DumpSegments(), reset the direction field to
NULL between iterations so it is recomputed for each component and
not keeping the first one ever guessed.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
Move towards more Python PEP8 compliance:
* All indentations sets to 4 spaces (in progress).
* In plugins, remove messages about software collections
and RHEL (too many case could wrongly lead to that).
Instead systematically uses "helpers.io.catch()".
* Put in lowercases all modules names. Note that C++ exported
modules *keep* their Capitalized names (to preserve the
identity with the C++ namespace).
* When making import, use full path.
* Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
the one ending in ".conf". Keep those who have not been ported
to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
C preprocessor macros by C++ templates. Applied first to configuration
from VLSISAPD.
This is unfinished business, just a limited demonstrator for now.
It is installed as a separate Python library "Cfg2" which do not
interact with the rest of Coriiolis.
The end goal is to fully remove boost and merge VLSISAPD useful
components directly inside Hurricane.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
"PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
and associated Resistor.py to make parameter conversion.
Currently we only uses vertical layout for resistors.
Added METAL2 horizontal terminals for resistors.
* Bug: In CRL::ApDriver::DumpSegments(), when saving RoutingPads build
on Pin *not* at the top level (that is, Pin from an instance),
use the pin's orientation to choose the segment type.
* NORTH/SOUTH becomes a Vertical.
* EAST/WEST becomes an Horizontal.
Formerly, the segment direction was guessed only for the bounding
box, leading to segments in incorrect directions leading to DRC
errors (in nmigen/ALU16, net "b(10)").
* Bug: In CRL/symbolic/cmos/technology.py, forgotten import for
WarningMessage.
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).
* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
them by "TerminalNetlist" one, especially Collections. Now we have
two clear sets of Collections to walkthough the layout or the
netlist.
Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
"TerminalNetlist" collections and apply the new semantic to the
locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
non terminal netlist instances to flag fully placed sub-blocks
as terminal for the netlist. Only then remove the feed cells
from unplaced instances. Previously, the feed cells where stripped
even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
Python None object when we do not want to pass one but need to
have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
renaming.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
unload Python modules prior to a full reset.
Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
the library list is empty. Should never occur except in case of a
botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
the catalog of a library and "saveCells()" to write back the cells.
Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
(improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
instead of a static one. This allow for it's correct resetting
across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
parser call. Needed to support database reset.
* New: In Hurricane::DBo, add an object counter to be sure that when
we perform a reset, no remaining DBo is allocated. This is different
of the object id which is ever increasing.
Note that, at reset, we check against "1" remaining element as at
this point only Database is still allocated.
Add a new "resetId()" method. MUST NEVER BE CALLED except by
DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
of all the libraries in reverse hierarchical depth order.
Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
loop of deletion over a collection for the shared pathes.
Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
various "qtFree()" of the sub-objects.
* Bug: In CRL/BlifParser::Model::mergeAlias(), when a signal is aliased
toward $true or $false in a Blif file (through a ".name" statement),
it was directly merged to "vdd" (resp. "vss"), and if it is an
external signal, this leads to its removal, potentially making "hole"
in its interface.
Now, create a gate zero or one for each tied up/low signal. This
way the interface is fully kept. At the cost of some supplemental
gates.
* Change: In documentation, now generate the overall documentation using
Pelican instead of Sphinx. This allows to have an unified approach
between the coriolis.lip6.fr website and the local documentation.
So we keep using "only" two doc generators: doxygen & Pelican.
* Change: In bootstrap/FindBoostrap.cmake, remove the -fsanitize=address
as it requires the "san" librarie which may be difficult to install.
* Change: In CRL/symbolic/cmos45/kite.py, decrease the METAL3 pitch from
10l to 8l. This is for testing with 4 routing metal only technology
like AMS c35b4 symbolic.
* Change: In Katana/BloatProfile, add static bloat option, that is, only
cell bloated in the first pass will be bloated again in subsequent
ones.
Add a "katana.bloatOverloadAdd" parameter to more easily control the
amount added to the computed overload.
* Change: In Oroshi, start integration of multi capacitors as generator.
Translate generator parameter into CapacitorStack ones. Add code for
routing unit capacitor.
* Change: In Hurricane::Viewer::ExceptionWidget & CRL/python/helpers/io.py,
downscale icons for non-HiDPI screen.
* Change: In CRL/etc/common/display.py, change the display threshold of
METAL1 layer so it do not appear at high scaling.
* New: In Etesian, activate the "setFixedAbHeight()" feature and export it
to Python. Allows to increase the space margin at constant height.
To be used by the P&R conductor.
* Change: In Unicorn/cgt.py, when running a script, insert the current
working directory at head of the sys.path, not at the end. So installed
modules do not shadow local one.
* New: In Anabatic::Edge, new accessor "getRawcapacity()" to know the full
capacity of the edge, that is, the real maximum number of tracks that
can go through the associated side.
* Change: In Katana/BloatProfile/Slice::tagsOverloaded(), bloating policy
change, now bloat all the instances under the GCell, not only the first
one.
* Change: In KatanaEngine::runGlobalRouter(), restore the search halo growth
policy to expanding of 3 GCells every 3 iterations.
New metrics displayed, the edge wire length length overload.
* Change: In cumulus/plugins/ConductorPlugin.py, now accepts the following
configuration parameters:
- "anabatic.globalIterationsEstimate", maximum number of global
iterations during the bloating computation passes.
- "conductor.useFixedAbHeight", tells wether the additionnal blank
space must be added so the aspect ratio is kept or the height is
kept (and the block become wider).
Disable the display of "rubber" to unclutter a little the view.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.
* Bug: In CRL/python/helpers/__init__.py, in textPythonTrace(), when an
ErrorMessage was catched, the trace parameter was not correctly
extracted leading to an "exception in exception".
* New: In Isobar/PyCell, exported Cell::getNonLeafInstanceOccurrences()
collection.
* New: In Isobar/PyTransformation, type is now built so the tp_compare
is linked to the C++ operator==().
* Change: In Hurricane::SelectionModel, Hurricane::SelectionWidget and
CellWidget, no longer use Occurrences but directly the Selector property.
We also use the Selector to know if an Occurrence is selected by
looking at that property on it's Quark. This avoid a very lengthy
search in vector when there is many elements (say > 10000).
NOTE: This is a bad implementation as there is a confusion between
beeing selected (that is, having a Selector property attached to
an Occurrence Quark) and being actually displayed as selected.
This lead to awkward implatation of the various "toggle" methods.
Have to rethink that more clearly later.
* Bug: In CRL::Histogram, the non-inline template full specialisation
of Measure<Histogram> must not be put in the header but in the module
to avoid multiple definition and link failure. They are actually
real, classic functions.
* New: In CRL/python/helpers.io, vprint() wrapper around print to display
messages according to the verbose level.
In etc/*, add messages in every configuration files so we may know
under which we are running.
* Change: In Hurricane::Isobar/PyHurricane.h, make the hash function use
the DBo id whenever possible instead of the object pointer, fall back
to it for standalone objects (Box like one). The DirectHashMethod()
macro generate a C style function (linkage) which call a template
function "getPyHash<>()" that uses a SFINAE mechanism to select
the right variant.
Create two comparison macros DirectCmpByPtrMethod() and
DirectCmpByValueMethod() to customize the comparison for objects that
have C++ operator==(). So now two boxes with the same contents will
be seen equal by Python. For DBo objects we keep the previous
comparison by C++ pointer.
* 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.
* New: In BasicLayer::Material, added "info" kind of material for layers
that are only informationals (i.e. not real GDS one). Created to
store geometric combination of layers, this is a temporary solution.
Have to define a clearer semantic for that.
* New: In CRL/helpers/AnalogTechno.py, new "Count" type for count numbers
that must not go through DbU::Unit converter. They are plain integers,
but stored in DbU::Unit (keeping track of that semantic is left to
the user).
* New: In Analog, added Analog::ResitorFamily & Analog::Resistor classes.
* New: In Analog, added inspector support for all Parameter classes.
* New: In Analog, new FloatParameter class (for resistor value).
* New: In CRL/etc/scn6m_deep_09/devices.py, added resistor device.
* New: In Oroshi, support for Resistors, stub for ResistorSnake generator.
* New: In Bora::DNodeSets, added support for Resistor devices.
* Change: In Bora::DSlicingNode, rename setNFing()/getNFing() into
setBoxSetIndex()/getBoxSetIndex() for semantic coherency.
* New: In Karakaze/python/AnalogDesign.py, added support for Resistor.
Change in addDevice(), the span which was only meaningful for
transistor devices is replaced by a parameter argument.
The parameter argument has to be consistent with the device type.
* 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.
* In CRL::Cyclop/CMakeLists.txt, add *again* the MOC files to the list
of .cpp . Don't know what is happening here with MOC under Qt 5.
* In CRL/python/helpers.io, cleanly fails if neither PyQt 4 nor PyQt 5 is
found. And tell it directly because this the module tasked to handle
the exceptions/errors...
* In Cumulus/plugins/AboutWindow.py, try PyQt 4 then PyQt 5.
* In documentation/UsersGuide, now tells explicitely that Qt 4 must be
used under RedHat 7 and Qt 5 under Debian.
* New: In bootstrap/coriolisEnv.py, add the "etc" directory to the
PYTHONPATH as initialization are now Python modules.
* New: In Hurricane/analogic, first groundwork for the integration of
PIP/MIM/MOM multi-capacitors. Add C++ and Python interface for the
allocation matrix and the list of capacities values.
* Change: In Hurricane::RegularLayer, add a layer parameter to the
constructor so the association between the RegularLayer and it's
BasicLayer can readily be done.
* Change: In Hurricane::Layer, add a new getCut() accessor to get the
cut layer in ViaLayer.
* Change: In Hurricane::DataBase::get(), the Python wrapper should no
longer consider an error if the data-base has not been created yet.
Just return None.
* Bug: In Isobar::PyLayer::getEnclosure() wrapper, if the overall
enclosure is requested, pass the right parameter to the C++ function.
* Change: In AllianceFramework, make public _bindLibraries() and export
it to the Python interface.
* Change: In AllianceFramework::create(), do not longer call bindLibraries().
This now must be done explicitely and afterwards.
* Change: In AllianceFramework::createLibrary() and
Environement::addSYSTEM_LIBRARY(), minor bug corrections that I don't
recall.
* Change: In SearchPath::prepend(), set the selected index to zero and
return it.
* Change: In CRL::System CTOR, add "etc" to the PYTHONPATH as the
configuration files are now organized as Python modules.
* New: In PyCRL, export the CRL::System singleton, it's creation is no
longer triggered by the one of AllianceFramework.
* New: In CRL/etc/, convert most of the configuration files into the
Python module format. For now, keep the old ".conf", but that are no
longer used.
For the real technologies, we cannot keep the directory name as
"180" or "45" as it not allowed by Python syntax, so we create "node180"
or "node45" instead.
Most of the helpers and coriolisInit.py are no longer used now.
To be removed in future commits after being sure that everything
works...
* Bug: In AutoSegment::makeDogleg(AutoContact*), the layer of the contacts
where badly computed when one end of the original segment was attached
to a non-preferred direction segment (mostly on terminal contacts).
Now use the new AutoContact::updateLayer() method.
* Bug: In Dijkstra::load(), limit symetric search area only if the net
is a symmetric one !
* Change: In Katana/python/katanaInit.py, comply with the new initialisation
scheme.
* Change: In Unicorn/cgt.py, comply to the new inititalization scheme.
* Change: In cumulus various Python scripts remove the call to
helpers.staticInitialization() as they are not needed now (we run in
only *one* interpreter, so we correctly share all init).
In plugins/__init__.py, read the new NDA directory variable.
* Bug: In cumulus/plugins/Chip.doCoronafloorplan(), self.railsNb was not
correctly managed when there was no clock.
* Change: In cumulus/plugins/Configuration.coronaContactArray(), compute
the viaPitch from the technology instead of the hard-coded 4.0 lambdas.
In Configuration.loadConfiguration(), read the "ioring.py" from
the new user's settings module.
* Bug: In stratus.dpgen_ADSB2F, gives coordinates translated into DbU to
the XY functions.
In st_model.Save(), use the VstUseConcat flag to get correct VST files.
In st_net.hur_net(), when a net is POWER/GROUND or CLOCK also make it
global.
* Change: In Oroshi/python/WIP_Transistor.py, encapsulate the generator
inside a try/except block to get prettier error (and stop at the first).
* Change: In Hurricane::Script, when running a script, no longer do it
inside a Python sun-interpreter, use the current one. This way we
no longer have our modules initialized twice or more, which was
starting to be unmanageable (with the NDA support).
The settings were re-read multiple time to the same value, so it
was working, but still...
I hope I didn't left some dangling Python objects now.
* Bug: In Hurricane::LayoutGenerator::drawLayout(), get the device abutment
box though a Pyhon object *before* finalizing which removes that objet.
* New: In cumulus/plugins/__init__.py, add a "loadPlugins()" and static
initialisation to preload plugins modules.
We use that pre-loading step to append to the module __path__ attribute
the alternate directory where a NDA covered may be found. This assume that
the directory tree under the NDA root is identical to the one under the
public root.
* New: In cumulus/plugins/chip/__init__.py, small utility function
importContants() to import the constants inside another module namespace,
to have more consise notations.
* Change: In cumulus/plugins/, in the various plugins sub-modules import
use the full path from plugins, that is, for example:
from plugins.core2chip.CoreToChip import IoPad
* Change: In Unicorn/python/unicornInit.py, no longer directly load the
plugins modules, this is now done by cumulus/plugins/__init__.py.
Instead, iterate through sys.modules for the ones starting by "plugins/"
and try to execute a Unicorn hook, if present.
* Change: In Karakaze/python/AnalogDesign.py, update for the new Instance.create()
prototype (added placement parameter).
* New: In CRL::ApDriver::DumpSegments(), drive as top-level segments the
RoutingPads using a Pin, and not only using a segment. They are not
exported as top level Pin but only as Segment as they do belong to
a deeper level.
* New: In Cumulus/plugins/PadsCorona.Side._placePads(), now manage both
"pxlib" and "phlib*". Pad library management is still hardcoded, this
should be made a configuration option someday.
* Bug: In CRL::cstDriver(), re-activate the management of the VstUseConcat
flag. Why was he removed in the first place?
* Change: In KatanaEngine::runGlobalRouter(), no longer give the details of
each overflowed edge and the complete list of impacted nets.
Only a count.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
katana.termSatReservedlocal
katana.termSatthreshold
for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
small I/O pads (supplied in phlib80). Tune various parameters of
Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
so RoutingPad will be build upon in global routing.
Do not complain when a I/O pad has a physical instance that did
not exists in the netlist. Just create it (appeared in phlib80).
When no netlist instance exists in a pad, the pad Cell is still
considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
target points instead of a segment. Needed to manage wide segment for
which the axis to consider is not that of the segment (one axis for
each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
all edges of a fixed amount (hTrackReservedLocal), guess the GCell
cluttering from the number of RoutingPads that it contains.
For non-saturated GCells, the four edges are decreased by the number
of RoutingPads. We use the maximum from the two neigboring GCells.
The hTrackReservedLocal parameter is now used only as a *maximum*
that the edge reservation can reach.
If a GCell is saturated (more than 8 RoutingPads, the saturation is
propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
flexible gauge name matching for terminal vertical extensions correction.
Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
position, even if it is a non-canonical segment. Maybe needed in the
initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
to manage coronas for Phenitec designs.
To avoid various side effects from segments being too close from
the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
wires was wrong. The axis to use to find the underlying GCells is the
one of the track, not of the segment. This was creating bad edge
capacity computation under the power ring of a block and subsequently
routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
METAL2 in non-preferred direction, restrict the terminal and turn
constraint box at the current position of the perpandicular, so it
doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
parameters:
katana.termSatReservedlocal
katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.
* 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 CRL::ApDriver & CRL::ApParser, when saving a fused net, do not
use it's name but put a star (*) character to set it anonymous.
Having all component named was creating problems in cougar and
subsquently in yagle (bad name for master latch).
Conversely, in the parser, if the name of the net is "fused_net",
make it a real fused_net and not an ordinary one.
