- New: ChipTools, regroup all datas and utilities to manage a full-chip
design.
- Change: In LoadGrByNet/GCellConfiguration::_GCell_xG_1Pad(), uses straight
perpandicular wires on top & right pads. The GCells under those connectors
are fully saturated, wires must go out as straight as possible.
- Change: In AutoHorizontal/AutoVertical, update the "terminal" flag after
slackening. This is to avoid global that are no longer connected to
terminals behave as such.
- Change: In AutoSegment::canMoveUp() & canPivotUp(), prevent all local segments
to go up. This is to avoid cluttering upper levels with small segments.
- Change: In GCellConfiguration, for xG_xL3, detect straight vertical topologies
and for them to be fixed (new flag FIXED_GLOBAL set by the topological
builder instead of the constructor). This prevent the router to do
stupid things...
To sets the "Fixed" flag *after* the axis of global segments have been
positionned correctly adds a "_toFixGlobals" static table lookup.
- Change: In GCell::stepDesaturate(), if less than one free track remains in
the upper layer, do not move up the segment. This allows from a minimum
free room for expansion.
- Change: In GCell::_getString(), display indexes and layer names in various
saturation tables.
- Change: In AutoSegment, allow move up of local Segment. ::moveUp() and
::canMoveUp() arguments go from booleans to flags, which are more
explicits.
- Change: Rename "obstacle" to "blockage" in all the places it still appears
to be completly homogeneous.
- New: In Catalog, adds a "Pad" attribute to mark cells that are pads.
- Change: In ApParser, discard "padreal" instances as a cause for a Cell to
be non-terminal. This is for LeafPlugOccurrences to consider the terminals
of those cells.
- Change: In ApParser, makes use of the new Pad flag in Catalog.
- New: Torus object. To allow a simpler management of a chip's corona,
the toric area between the pads and the core.
- Change: In HyperNet/LeafPlugOccurrences, change the instance stop criterions
from "isLeaf()", which means "contains no instances" to "isTerminal()"
which can be programmatically changed. This has to be done for the Pads
which are non-leaf due to "padreal" but still must be considered for their
connectors.
This modification is coupled with one in the Ap parser.
- Change: In Backtrace, enable support for Apple backtrace. This is a blind
test as I can't check by myself.
* ./hurricane/src/viewer:
- Change: In CellWidget/SelectionModel/SelectionWidget, rewrite the Gos selec-
tion mechanism. Now ExtensionGo could be selecteds as they ought to be.
Also adopt a more standard way of how objetcs are selecteds.
Prefer "dataChanged()" signal over "reset()" or "layoutChanged()" as
it keeps the selection instead of resetting it.
Unselecteds entry in the window (toggled with 't') are now shown in
red for better readability.
* New <subCircuitsPathes> section in <circuit> that lists the pathes that contain subCircuits xml files
* New Device object that inherits from simplified Instance object.
- Instance has a name, a model, some connectors and optionnal parameters
- Device has the same attributes plus mosType, sourceBulkConnected and transistors
* Updated readFromFile and wrtieToFile methods to support these modifications
* Updated parse and drive examples to support these modifications
- Note: only C++ examples has been updated since my boost.python environment is actually totaly broken
* New buffer.xml example that uses subCircuits.

* New buffer.xml example that uses subCircuits.
- New: Inspector support enabled for AllianceFramework and most of it's
sub-objects. Attached as a property on the DataBase to be browsable
through the Inspector.
- Change: Now also read a <.coriolis2.configuration.xml> in the user's
root account (before the directory specific one and after the system-
wide).
- Change: In verbose mode, also display what environment files are being
read.
- Change: No more reference to CRL_CATA_LIB in error messages.
- Change: Suppress stratus2sxlib obsolete library.
Recently adds have been adjusted in PyDtr.py
Examples have been updated (c++ is tested, python fails on my Mac due to a strange python2.6.6 behavior I have to check this)
getRule method of Techno does not throw exception anymore if rule is not found : a NULL Rule* is returned instead.
but getValue methods throw exception if rule is not found
- New: In CgtMain, support for Stratus script execution from command line:
"--stratus-script=<script_file>" (whitout ".py" extension).
- Change: In CgtMain, makes use of priority for configuration settings.
- 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.
- Bug: Uses correct Contact with for rings.
- Bug: Reorder import so that CRL is always imported first so that the
problem of duplicated type_info RTTI doesn't show.
- New: In BuilPowerRails & BuildBlockage, specific support for chip-level
design. The Alliance "top chip" design hierarchical structure is
hard-coded. Top level POWER/GROUND/CLOCK nets must always have the
<vsse>, <vdde>, <ck>, <vssi>, <vddi>, <ckc>, <cki> names.
Specific method to get trans-hierarchical root nets, espcially in
case of global ones (POWER/GROUND). Clock is *not* global.
Some correction in the manner obscured tracks are computeds.
- New: ProtectRoutingPad module that perform a more clean work for protecting
unused RoutingPad.
- Bug: In BuildPowerRails, uses stable_sort<> instead of sort<>, which
causes unexplained core dumps (seems to try to perform a comparison
using the "end" pseudo element). Already occured in Knik, no explanation
other than a STL bug.
- Change: Slight changes in the weights to move up. Now needs a full empty
track instead of a half one.
- Change: In loadGlobalRouting(), more exlicit message as to why a net is
filtered out the routing set (POWER, GROUND, CLOCK or BLOCKAGE).
- New: ChipTool, module with utilities specific to chip routing. Containing
a function to pre-break wires around a block.
- New: In loadGlobalRouting/GCellConfiguration, adds supports for RoutingPad
connected on chip's pad.
- New: In GCellGrid/GCell, can compute the density in three modes: average,
max of H/V and max of layer. Currently implemented in getMaxHVDensity(),
should be unificated with getDensity(). Used for display purposes.
- Bug: In AutoContact, when splitting a contact, add a specific check for
"one layer span".
- Bug: In AutoSegment::canMoveUp(), do not move up fixed segments.
- Bug: In Edge::getCost(), when the edge capacity is null, return maximum
cost (HUGE).
- Bug: In Knik::saveSolution(), saves only Segments that belongs to global
routing, that is in GMetalH/GMetalV.
- New: In Utilities, uses the new Backtrace to print the stack before
core-dumping.
- New: In Environment, pattern recognition of Pad model names.
- New: In AllianceFramework, pattern recognition of Pad model names.
- Bug: In Measures, add inspector support and uses pointer to prevent using
copy construction. Makes the inspector to core-dump.
- New: In RoutingLayerGauge, inspector support for Constant::Direction.
- Change: In ApDriver, correct managment of BIGVIA sizes. BIGVIA in one
metal keep their sizes, but BIGVIA whith cut must be expandeds to
contains their enclosure in metals. In Hurricane VIA size are relatives
to the cut but in Alliance, to the biggest metal.
Generate correct direction (always UP or RIGHT) for segments.
- Change: In ApParser, shrink BIGVIA to the size of their cut from the
Alliance format. Avoid VIA "bloating".
More thorough verification of Segment data coherency, mainly with
direction.
Suppress warning of non-existent logical instance in the special
case of "padreal".
- Change: In VstParserGrammar, perform an explicit plug connection on globals
Nets if the names of globals Nets differs.
- New: In display.xml, add style for printers (B&W).
- Bug: In technology.symbolic.xml, BLOCKAGE6 was associated to metal6 instead
of blockage6.
Correct extensions value for VIA metal layers above cut1.
- Bug: In Utilities, in System singleton constructor check of duplicated
type_info/RTTI initialization. Occurs when python modules are useds.
CRL must always be included first.
- New: Backtrace to print the stack when an exception is thrown.
- New: In Error, support for Backtrack.
- Change: In TextTranslator, provides a default HTML translator instead of
building it every time it was needed.
- Bug: In Common, when demangling a C++ symbol fails, returns the empty
string instead of NULL.
* ./hurricane/src/viewer:
- New: In Exception, support for the Backtrack new feature.
* ./hurricane/src/isobar:
- Change: In PyHurricane, when catching a C++ exception, adds a newline to
have a more clean display.
- New: In Parameter, adds a priority for all the mutators method calls.
Allows to sets values according to where they came from instead of
only taking the last change. This is needed because we cannot ensure
that the last sets value is the truly wanted one. Four priorities
are avalaibles (in increasing order):
1. - ApplicationBuiltin (the default).
2. - ConfigurationFile (currently: the XML parser).
3. - CommandLine (supplied by the command line, see Unicorn).
4. - Interactive (changed through ConfigurationWidget).
- New: In ConfigurationWidget, hideTabs()/showTabs() to explicitly select
which tabs are displayeds or hidden. Two modes are avalaibles:
Incremental and Exact. In Exact mode only hidden tabs are hiddens and
only shown tabs are shown.
- Change: In ConfigurationWidget/ConfTabWidget/ParameterWidget, no longer
relies on the Widget parent/child tree to find the ConfigurationWidget
from a ParameterWidget (consequence of the hide/show capability which
is implemented by cutting off hidden tabs). Adds an explicit attribute.
- New: In Query, adds an accessor to get the current path.
- Bug: In NetExternalComponents, every component of an external net was
considered as an external one. Now only truly external components
are considered.
* ./hurricane/src/isobar:
- New: StratusScript, dedicated Stratus script laucher.
- Bug: In CellWidget, when drawing selecteds Gos, the loop variable was
not reset between loops resulting in incomplete display.
* ./hurricane/src/isobar:
- New: In PyHorizontal & PyVertical, adds mutator methods.
- Change: In ConfigurationWidget, two separate signals for "confOk" and
"needRestart", rewrite of the "apply clicked" method.
- Bug: In LogEntry::restore(), uses correct flags on Paramater::setString().
- Change: Internal rewrite of the check function, now named _doChange()
and shared by all mutators.
- Change: Logs now contains entries with the last correct value and are
able to restore that value.
- Change: LogWidget simplificated, only one message label. But now two
buttons (Continue/Cancel).
- Change: In ConfigurationWidget, two steps validation "mustExist" then
"needRestart".
- New: Attributes "needRestart", "mustExist", "isFile" and "isPath".
- New: Display a warning message when a parameter with mustExist or
needRestart is modificated.
- New: In ConfigurationWidget, method selectTab() to select the current
displayed tab.
- Change: In Configuration::writeToFile() and writeToStream(), adds a
third parameter telling which parameter to save. It's a semicolon
separated list of parameter head id. Example: "kite;mauka".
- Bug: In FilePathEdit, do not sets the file/path if the Dialog has been
cancelled.
- Bug: In FilePathEdit, do not uses the native dialog (called by static
methods) when under Linux/GtkStyle as the native widget seems to be
badly linked (bug in GtkStyle?).
