* Change: In Isobar, the Python interface was not exactly mirroring the
C++ one, now it is the case. The Python code should look likes almost
exactly like the C++ one, the only differences remaining being due
to the languages respective syntaxes. Note that in the case of
constructor functions, it leads to a slightly longer notation in
Python that it could have been (mimic the ".create()" static
member). Main modifications:
1. Mirror the static constructor syntax with create():
Cell( ... ) ==> Cell.create( ... )
2. Correct hierarchy for constants in Instance, Net, Pin
& Transformation. For example:
Hurricane.PlacementStatusFIXED
==> Hurricane.Instance.PlacementStatus.FIXED
Hurricane.OrientationID
==> Hurricane.Transformation.Orientation.ID
Hurricane.TypeLOGICAL ==> Hurricane.Net.Type.LOGICAL
Hurricane.DirectionIN ==> Hurricane.Net.Direction.IN
* Change: In CRL Core, correction to match the improved Python API
in the configutation helpers.
* Change: In Cumulus, correction to match the improved Python API.
* Change: In Stratus, correction to match the improved Python API.
* Change: In Documenation, update for the new Python interface
(both user's guide & examples).
* Note: We must port those changes into Chams for it to continue
to run.
* Change: In Documenation, update the Python script support part.
- New: Added FreeBSD/Ubuntu patches from Otacilio De Araujo
(<otaciliodearaujo@gmail.com>).
* ./stratus/src/stratus.py
- Change: Configuration is now read through the new python C/API
system. No more st_config.
- Bug: During the packaging stage, DESTDIR must be appended to the
pathes prepended to CMAKE_MODULE_PATH.
* ./stratus:
- Bug: In dpgen_RF1.py, small typo for the python executable if the module
is to be run stand-alone. Never show in normal uses.
- Bug: In ROM_encours & dpen_ROM, correct bad indentation.
- Change: In st_model, separate View() in two methods, one that load the
model into the editor (still named View()) and a Breakpoint() method
for putting true stop points. The Breakpoint() method calls the
View() method. Will simplificate my explanations to the students...
- Change: Add support for chip-level nets. POWER/GROUND/CLOCK as signals.
- Bug: Reorder import so that CRL is always imported first so that the
problem of duplicated type_info RTTI doesn't show.
- 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.
* ./stratus1,
./cumulus:
- Change: Replace calls to CRL.getAllianceFramework() by CRL.AllianceFramework.get().
