SPICE simulators don't like to have the same model defined twice.
As we have a "one file per model policy", then we must include the
model file only once. This is particularly critical for standard
cells. So now, the driver include all the models in the top level,
both terminals ans intermediate. And the sub-models include nothing.
We stop at the "TerminalNetlist" level.
Add an option flag througout all the Spice driver hierarchy to
convey that information.
The structure of the driver is copied from the Vhdl one. It is not
integrated as a an AllianceFramework one but as a standalone like
GDS. For now use numerical indexes for electrical nodes but also
support strings. The nets are ordereds in reverse alphabetical
order, but a custom order can be defined, if we read the model
from an external SPICE subckt (to be done).
SPICE saving has also been added to the cumulus/rsave plugin
and the block/chip P&R one.
* 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 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.
* 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 CRL::DefImport, added callback to read the DEF UNITS statement
and perform a correct length conversion. Previously set to read pseudo
lambdas in hundredth of microns.
Added DefParser::getLefCell() to lookup master cells in the LEF
libraries before looking in the Alliance ones (rooted under "LEF"
library).
* Change: In CRL::LefParser::_pinPostProcess(), when no segment suitable
for terminal connexion is found, add all of them. This is a quick hack
and an a correct policy that match all techno must be implemeneted.
* New: In CRL::pyCRL, add a Python wrapper for DefImport.
* New: In CRL/etc/45/ispd18/ added configuration files for the "real"
technology used by the ISPD18 45nm design benchmarks.
* New: In CRL, implement a GDSII parser. The complete syntax is supported,
but only a few subset is really taken into account. It is intended to
load the layout of standard cells only. The interface of the cell is
provided through a LEF file and it complete layout through the GDSII.
The loader work in a Library way. It takes a Hurricane library as
argument and search in the GDSII library structures with a name
matching the Cell of the library and complete them.
* Change: In Hurricane::Component, put the Contour methods at Component
level so we can use them in a generic way in the CellWidget drawing
primitives.
* New: Hurricane::Rectilinear polygon, for small rectlinear polygons.
Should be less than 100 vertexes. For bigger ones, use Polygon
which allows slanted egdes.
* Bug: In CRL, freepdk_45/technology.conf, there seems to be an incoherency
bettween the GDSII layer numbers as defined in the Cadence FreeePDK45.tf
file and the one used in the supplied layout of the GDSII cells.
For now, we align on the GDSII cells to get nice layouts, but it
has to checked.
* New: In CRL Core, added LEF importer for real technologies. This is
still a work in progress. Exported in Python interface.
* Bug: In CRL Core, CellGauge::getRecord() correctly display DbU
attributes.
* Change: In Unicorn, mofificate ImportCell and ImportCellDialog to
support the LEF importer. Add a template layer so we can work with
loaders returning Cell* or Library*.
* Change: In Unicorn::UnicornGui::getCellFromDb(), in addition to the
Alliance loader, uses the DataBase::getCell() too (for Cells that
are *not* in Alliance).
* Change: In Hurricane Commons.h, even when cdebug print nothing, it slow
down the program (three times for Kite!). Create a macro cdebug_log
which calls cdebug *only* if the debug level is active.
* Change: In Hurricane, in Flags add operator overload for "int" type
and not only "unsigned int". Otherwise the compiler complaints about
ambiguous overload when using enum values which are considered as
"int".
Simpler code for the BaseFlags::contains() method.
Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
two trace systems (trace & ltrace) by a stream-based one.
As it is a true object it is much less fragile than the one based
on defines (but maybe a little slower).
Define a reservation table for the trace levels for all the
Coriolis & Chams components.
* Change: All tools, use the new trace system.
* Bug: In Hurricane, in HApplication, ExceptionWidget ans PyHurricane.h,
forgot to catch the Hurricane::Bug exception which was leading to
terminate() without explanations.
* Change: In Katabatic, In GCellTopology, now support one GCell with
five metal1 terminal of the same net. This unlikely configuration
did appear in the SNX for the first time...
* 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).
* Bug: In CRL Core, in Vst driver, remove VhdlEntity (from Cell) and
BitProperty/Bit (from Net) with the property remove and not the
destroy() method. The BitProperty removal was completly forgotten
leading to the use of removed Signals when doing multiple saves
(hence core-dump).
* Change: In CRL Core, in Vst driver, never save as Signals the DeepNets
as they are created by a virtual flatten and do not connect any
instances at top level. Note that they will exists in the physical
file if routing layout has been created.
* Bug: In Hurricane, in NetAlias, bad Record construction of the _next
field.
* New: In CRL Core, in VstDriver complete replacement of the old Vst
driver. Needed cleaner architecture to manage correctly files
importeds through the Blif parser, which are Verilog like.
It is build as an extension trough property and is not kept
in sync with the Cell. So it's use should be transient only.
* Change: In CRL Core, in NamingScheme forgot to change '.' (dot)
forbidden character into '_'.
* Change: In Cumulus, in the RSave plugins, remove the VHDL extensions
after saving.
* New: In Hurricane, In Net & Cell, support for Net aliases names.
Use a structure based on a simple ring of NetAliasHook. The Net
holds a global map, sorted by names of all the aliases of all Nets.
Elements NetAliasesHook of the map are slaves of ring whose master
is an attribute of the Net (it is *not* in the map, as the primary
name of the Net).
In case of merge, the aliases of both Nets are merged and the
name of the merged one become an alias.
The Cell::getNet() looks in both the Net map and the aliases to
find a Net by name.
* Bug: In CRL Core, in coriolisInit.py, reoder the loading of the
configuration files so the real technology is read as early as
possible to set up the <gridsPerLambda> factor before any lambda
is actually computed...
* Bug: In CRL Core, in AcmSigda, do not try to fed the file when it
has failed to be opened. Throw a clean exception instead.
* New: In CRL Core, in Toolbox, add a NamingScheme object to convert
a design into VHDL compliant names (mainly from Blif/Verilog).
This is extensible in any case.
* New: In CRL Core, in BlifParser, slightly more informative warning
messages. Align the loading progress information on the other
parsers.
Add a capability to select which component of the design will
be returned, if there are more than one. Use the "." as separator.
For exemple you can request "Processor.Alu", which will load
the "Alu" component from the design in "Processor.blif".
To be able to save a Blif loaded design, systematically convert
all the name for VHDL compliance, as it is the format used by
the Coriolis native files (vst).
Export the Blif parser to the Python interface.
* New: In Kite, In NegociateWindow, add a counter of the number of
remaining events. Gives an idea of the ETA...
* New: In Unicorn, in cgt.by, add an option to load a Blif design from
the command line.
* New: In Cumulus, new RSave plugin to save both netlist & layout.
Partly redundant with the previous one. Have to better organize
that later.
Cleanup:
* Cleanup: In <vlsisapd/src/bookshelf>, remove unused file Bookshelf.cpp
(may have been a parser once upon a time).
* Cleanup: In <hurricane>, in Cell::flattenNets() use flags instead of
booleans to be more readable. Allow occurrence placement checking.
* New: In <crlcore> add Python wrapper for the Ispd05 loader.
* New: In <unicorn> add option for direct loading of ISPD05 designs.
* Bug: In <hurricane/src/viewer>, RecordModel must emit
layoutAboutToBeChanged() before changing the record contents (and
layoutChanged() afterwards).
- A complete sweep of cleanup to suppress allmost all compiler warnings.
* ./crlcore:
- New: Extented Python support for all objects needed to configure Coriolis.
- New: Configuration files and load helpers completly written in Python.
An XML emulation mode is still avalaible.
- New: UsersGuide, as a replacement for README, written in ReST.
- New: Start of Doxygen documentation (mostly for documenting the initialisation
objects & methods).
- Change: New problem identified with the Python modules: each module seems
to be built as a complete binary, so all the static C++ initializers are
allocated in each module. In particular the C++ tree inheritance is built
for *each* module so we cannot longer uses the typeid() comparisons
across modules... It was used by boost::program_options to perform is
casts with boost::any and was starting throwing exceptions because of
bad casts. program_option was first initialized in "configuration"
first included by PyViewer then in PyCRL (see Utilities.cpp).
A first solution is to re-order the import of Python modules in
stratus1/st_model so that CRL is imported first.
The second is to not not link "configuration" with boost::program_option
as only the binary vlsisapd-conf-editor needs it.
That is a serious problem of which we must be aware and can cause further
strange behaviors.
Debug code used to diagnostic has been kept commented in the sources a
it may be needed again :-(
This behavior do not affect our singletons because they are part of
dynamic libraries that seems to be correctly shared between the various
Python modules.
* ./crlcore:
- In PyCRL, module method "getAllianceFramework()" moved as static object
method "get()" of AllianceFramework. Object AllianceFramework added
to module CRL.
- Bug: target_link_libraries() must be put back for OSX Snow Leopard
(doesn't seems to affect Leopard). As I do not have an OSX under
my hand it's untested and is likely to fail at that point.
* ./crlcore:
- New: PyCatalog & PyCatalogState python wrappers, mainly to have constants
values for stratus1 parsers/drivers.
