* New: In Hurricane::NetRoutingProperty, add and change the meaning
of the following flags:
- ManualGlobalRoute : now means that a global routing *trunk*
is present, made of "gmetalh", "gmetalv" & "gcontact".
- Manualdetailroute : added, get the former meaning of
ManualGlobalRoute, that is, the detailed routing is
already present for this net, but can be changed by the
detailed router. Implies that it respect the Terminal,
HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
segments from the ripup. Change the segment sorting function
so that thoses segments are put in head of list (considered
as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
global routed and manual detail routed signals, and tag them
accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
managed by the gauge (comparison by mask).
* New: In flute, added a Python binding. Contains two methods: "readLUT()",
to load the POWV9.dat and POST9.dat and "flute()" to build a RSMT.
"flute()" takes a tuple of positions (themselves 2-uple) like:
( (x0,y0), (x1,y1,), ... (xN,yM) )
and returns a tuple of 3-uple of branches:
( (n0,x0,y0), (n1,x1,y1), ... )
In "flute.h", set the distance type (DTYPE) to int64_t to always
accomodate DbU::Unit.
As it now uses the Hurricane Python interface and the path utilities
from CRL Core, move it's compilation *after* them (see build.conf in
bootstrap).
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
This commit contains two set of features that should have been commited
separately.
1. Compliance with clang 5.0.1, tested with the RedHat collection
llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
with Xcode & macports. The bootstrap install system has been modificated
accordingly.
2. The basic support for routing density driven placement. Related
features are:
* Bloat property. Each Occurrence of an Instance can be individually
bloated. This property not attached to any tool to allow the placer and
router to share it as wanted. Nevertheless, it is defined in Etesian.
* BloatProfile in Katana, add individual Bloat properties to Instances
occurrences based on the East & North overflowed edges of each GCell.
* Support in ToolEngine for a "pass number" of a tool. This pass number
is mainly used to make "per pass" measurements. The MeasureSet system
is improved accordingly to support multiple values of a same measure.
* Embryo of "P&R Conductor" to perform the place & route loop until the
design is successfully placed. May be the first brick of a Silicon
Compiler.
* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
instance occurrence BloatProperty dependency.
Added option support for the "llvm-toolset-7" collection to build
against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
for first & second arguments must be called with <const T> and <const U>
as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
template has a static member "_name". Clang did show that the template
for this static number has to be put inside the namespace where the
template *is defined* (i.e. Hurricane) instead of the namespace where
it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
(clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
(clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
current working directory in the sys.path as in certain configuration
it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
encountering a RoutingPad on a top-level Pin Occurrence. The segment
was generated in the wrong direction, creating DRC violations on the
"mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
Now, each kind of measure can accept multiple values put in a vector.
The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
was wrong, it was always returning true, which broke the "strick weak
ordering" of the comparison.
This was producing a core-dump in GCell::updateDensity() when sorting
a vector<>. The end() iterator was being dereferenced, leading to the
problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
whose axis is perpandicular to the symmetry axis was wrong
("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
and selectBloatedInstances() to automatically select segments from
overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
between global and detailed.
Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
driven placement.
