- 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.
* ./mauka:
- Change: In CMakeLists.txt, makes Mauka compliant with OSX (case sensitivity).
- Bug: target_link_libraries() must be put back for OSX Snow Leopard
(doesn't seems to affect Leopard). As I do not have an OSX under
my hand it's untested and is likely to fail at that point.
* ./mauka:
- Bug: Place intermediate levels of instances, so that they show up in
the top level.
- Change: New InsertFeeds method + module, sadly we cannot insert the feeds
cells in one merged step with the BBPlacer as the SubRows do not cover
the entire surface due to fixed Cells.
- Library linking: there must not be "target_link_library()" for libraries,
only when building binaries. Avoid clashes between static module
or class variables, and strange reinitialisation of those variables.
- Change: Boost is now always linked staticly.
- Change: In doQuadriPart, manage correctly non-square designs. So that
after an initial non-quadripartition step, the partitions are rougly
squares. Seems to have trouble with small designs.
./metis,
./mauka,
./katabatic,
./kite :
- Change: switch toward the XML configuration system. Suppress the need
of a default static configuration (now built on demand from the XML
database).
In Mauka and Kite, suppress the ConfigurationWidget, wich are
obsoleted by the generic XML configuration widget.
- New: In ConfigurationWidget, add support for hMETIS partitionner.
- New: Static method doQuadriPart() to perform recursive quadri-partionning
of the circuit. Down to the instanceStopCriterion and with metis/nimbus.
Ported from pycoriolis.
- New: MaukaEngine::regroupOverloadedGCells() also imported from pycoriolis.
- New: hMETIS support.
- Change: In Configuration, now CellGauge characteristics are supplied only
through Configuration.
- Change: In SubRow, change the way bin widths are computed.
- Bug: In Surface & MaukaEngine, lengthes that are "proportional" to areas
are now coded with double instead of DbU::Unit, because of capacity
overflow.
