* Bug: In LefImport::_macroCbk(), the GDS file must be loaded *before*
we start putting nets & components from the LEF file. The GDS parser
must find an blank slate and not try to modifies nets already
created by LEF.
This way, we really can modify the GDS layout to suit the LEF
statements.
Note that we may end up with two set of terminal exactly overlapping,
a Pad from the GDS and a Segment from LEF.
* Change: In GdsParser::xyToPath(), we were creating articulated layout
segments over contacts using the "all_nets_merged_in_gds" common net.
But some segment may later be promoted to interface, that means
deleting the previous one and re-creating it with the right
external net.
The deletion was automatically creating a rubber between it's two
Contact anchors. And we there is no way to get rid of it (other than
also removing the Contacts).
* New: In helpers.overlay.CfgDefault, new class that can be used to give
a default value to a cached configuration parameter. The default
value will be used as a last ditch fallback and used *only if* no
default value can be fetched from the C++ database (disk).
* New: In LefImport, add setGdsForeignDirectory() to point out from where
to load the extra GDS file in case a FOREIGN directory is present
in MACRO.
Also add support for merging the supply nets. It may happens that
the supply nets have different names in the GDS ("vdd!") and LEF files
("pvdd"), in that case, the LEF name supersede the GDS one.
The GDS file will be loaded *first* then completed by the LEF contents.
Blockage in the GDS file are *not* loaded.
* Change: In GdsParser, perform an early recognition of supply nets. For now
it's hardwired to names starting by "vdd" and "gnd", but should be
parametrized in the future.
Needed for the LefImport to merge, if needed, the power supplies.
In GdsStream::xyToComponent(), skip the blockage if required.
* Change: In LefImport::_pinCbk(), if a pin has "USE POWER" or "USE GROUND"
make it a global signal (previously flagged only "!" appended to name).
* Change: In LefImport::_pinStdPostProcess() do not try to find "on grid"
components for supply nets, just make all their components externals.
* New: In boostrap/FindBootstrap.cmake, add a macro setup_qt() to
share Python detection across the various tools.
This macro takes into account the USE_MANYLINUX variable to
slightly change the Python detection. On a "normal" system we
look for "Development" (search for dynamic libraries) while under
manylinux we look for "Development.Module"(static linking).
* Change: In bootstrap/ccb.py, add a new option --manylinux.
* Change: Cleanup in the various CMakeLists.txt to use setup_qt().
* 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.
* 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.
* New: In CRL::RoutingLayerGauge, two new types of gauge are supported:
- Unusable : just do nothing with it, but the layer is stacked.
- BottomPowersupply : can be used for supply routing only, and
is *below* the normal routing layers (instead of on top as
usual).
Both new types must be *below* the real routing layers.
* New: In CRL::RoutingGauge, add a new attribute "firstRoutingLayer"
to give the index (depth) of the first layer usable for routing.
(not Unusable and not BottomPowerSupply)
* New: In Anabatic::Session & Anabatic::NetBuilder, in order to build
the initial wiring, provides (Session) and use (NetBuilder) the
new functions:
- getBuildRoutingLayer(depth)
- getBuildContactLayer(depth)
Thoses functions takes into account (offset) the unusable layers
so depth 0 is the first usable routing layer, and so on.
* New: In Technology, in order to support symbolic technology on top
of a real technology using non-generic layer names, it comes in
handy to be able to define layer alias names. Generic *real*
layer names could be defined as alias over the technology
specific ones. Then, we can build the symbolic layers upon
the generic names (so *that* part of the init code can be
shared between techs).
Adds Technology::addLayerAlias()
The semantic of Technology::getLayer() changes a little, it
return the techno layer associtated to the name *or* the
aliased name.
* Bug: In Technology::_addPhysicalRule(), in case of a rule redefinition,
we were using it's name *after* the deletion of the rule object.
Nasty crash.
Improve the error message by giving the name of the conflicting
rule.
* In CRL/helpers.analogtechno, add an addDevice() function to load
analogic devices descriptors (copied from the old init system).
* In CRL/ApParser, if an exception is catched, tells in which file and
line it did occur.
* In Oroshi/dtr.Rules, add a translation step to get the rule names
from the technology. From generic names to actual technology
layer names.
Add some documentation.
* In Oroshi/stack.Stack, get the layers names through dtr.Rules to get
the layers names translated.
