In CoreToChip, the "iolib" I/O pad library an alternative to the "cmos"
one. "cmos" uses the pxlib library while iolib uses a symbolic abstract
version of the C4M (real) I/O pad.
The initialization is a bit split as the "cmos" library are part of
Alliance, while "iolib" is in alliance-check-toolkit. So "iolib" is
added at designflow.technos.setupCMOS().
Setup additional configuration parameter directly in:
core2chip.niolib.CoreToChip.__init__().
* Bug: In CRL/technos.node180.gf180mcu_c4m.iolib.py, remove the VDD and
VSS ring terminals in the pad as only *some* of the have it.
Assume that it is a bug from GF. The power rail will still be ok
as it connect by abutment (with the filler & other I/O pads).
* New: In cumulus.plugins.block.configuration.py, added support for
iterable I/O pad specifications in ioPads argument.
* New: In cumulus.plugins.core2chip.core2chip.py, add support for
any number of control signals on I/O pads. Not fully implemented
yet, as we only allow to hard-wire them either to one or zero.
Raise an error if _connect() fails to find a master net, so
we don't fail strangely later...
* New: In LefImport::LefParser, add support for LEF Polygons that are
translated into Hurricane Rectilinears.
* Change: In LefImport::setMergeLibrary(), the default behavior for the
LEF parser is to create a new separate library under LEF/<lib_name>
for each file. But if the various cells are put each one in it's own
cell, this is suitable. So we can now set a library beforehand into
which they will be all put.
* New: in CRL/technos.node180.gf180mcu, configuration files for the
GF180MCU open PDK.
* New: in cumulus/designflow.technos, added a setupGF180MCU_GF() to
initialize the GF PDK.
* In cumulus.designflow.technos.setupCMOS(): export back the guessed
ALLIANCE_TOP *before* importing technos.symbolic.cmos so it is
used for the CELLS_TOP. This avoid defaulting to /soc/alliance
which does exists only on LIP6 computers...
* Move all Python stuff under a common Python namespace "coriolis".
* Instead of having a series subtrees for each tool, integrate
everything in one common tree. So now, all components can be
located either with an absolute path from "coriolis" or, inside
cross-reference themselves through relatives imports.
* As a consequence, we only need to add ".../site-packages/coriolis/"
to the PYTHONPATH, and not a whole bunch of subdirectories.
And nothing, if installed in-system.
* The tree of free technologies configuration files is also moved
below "coriolis/technos" instead of "/etc".
* Supressed "cumulus" level for the plugins.
* All python modules are rewritten using relative imports except
for the configuration files that uses absolute import as they
can be cloned outside of the tree to serve as templates.
* Change: In boostrap/FindPythonSitePackages, include "/coriolis" in
Python_CORIOLISARCH and Python_CORIOLISLIB.
Provide a Python_SITELIB *without* "/coriolis" appended.
* Change: In cumulus/plugins/__init__.loadPlugins(), must prefix modules
read in the plugins directory by "coriolis.plugins.". No longer need
to add their path to sys.path.
* Change: In crlcore/python/technos/nodeX/*/devices.py, the scripts of
the layouts generators must be prefixed by "coriolis.oroshi.".
* Change: In CRL::System CTOR, no longer add the pathes of the various
plugins to sys.path. Only "site-packages/coriolis/".
* New: In Utilities::Path::toPyModePath(), new method to convert a
filesystem path into a python module path.
Examples:
"coriolis/plugins/block" --> "coriolis.plugins.block".
"coriolis/plugins/rsave.py" --> "coriolis.plugins.rsave".
* Change: In katanaEngine::_runKatanaEngine(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In BoraEngine::_runBoraEngine(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In UnicornGui::_runUnicornInit(), rename the hook script
initHook.py. No longer need to modify sys.path.
* Change: In cumulus.plugins.chip.constants, put the constants
outside __init__.py to avoid a loop at initialization.
