* 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...
Formerly, the H-Track could be shifted *relative* to the position of
the center of the RoutingPad. Which may become fragile in case of a
change in the standard cell library. So we create a new feature allowing
to specify the H-track as an offset *from the bottom of the slice*.
Two offset can be specified:
* spares.htreeOffsetDriver : for the main H part, connected to the
driver.
* spares.htreeOffsetSink : for the small parts connecting to every
fours sinks of the tree.
This to avoid those two to overlap. The sink of the "N" stage with
the driver of the "N+1" stage (so input & ouput of the same buffer).
* 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.
