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.
* 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.
* In cumulus/block.configuration, the rsave method was buggy. It did stop
it did not save "terminal" master cells (i.e. a cell without instance)
instead of "netlistTerminal" (explicitely flagged for standard cells).
The result was that some "empty netlist" in the complete "ls180"
from LibreSOC went missing. Causing cougar to complain.
Note: The port is not complete. Integration of LKCL patches will
follow shortly.
* Change: In cumulus/plugins/alpha/block, more simple inheritance
scheme. Use classic inheritance instead of @classdecorator.
BlockConf (renamed from BlockState) now inherit from GaugeConf,
Double inheritance tree, for Block/Chip and BlockConf/ChipConf.
Allow an uniform syntax for configuration parameters.
* New: In cumulus/plugins/alpha/chip, port of the chip plugin and
integrate with the block plugin. It is now a derived class of
Block. ChipConf is also a derived from BlockConf.
Obsolete "./coriolis2/ioring.py", all informations are given
though the ChipConf state class.
* New: In cumulus/plugins/alpha/core2chip, only Alliance/pxlib is
ported yet.
* Bug: In cumulus/plugins/rsave.py, use "Cell.isTerminalNetlist()"
instead of "Cell.isTerminal()" to find the hierarchical stop
points.
If the root cell to be saved is itself a *terminal netlist*
one, save it anyway. The top level *must* be saved regardless to
it's status.
* 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/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.
