- New: In GraphicsParser, read the new darkening scheme (HSV ratio).
"display.xml" configuaration file modificated accordingly. May be some
tuning needed for white background styles.
- 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: In tools.configuration.xml, add default values for METAL minimum break
lengths.
- Change: In AcmSigda, makes the parser an autonomous one, like for ICCAD or
ISPD.
- Change: Remove AcmSigda, Bookshelf and LEF/DEF parsers from the Alliance
builtins. They are now to be used through import/export.
- Bug: In Utilities, the <misc.logMode> parameter boolean parameter was used
the wrong way (true/false).
- New: In AllianceFramework constructor, now look for an XML configuration
file in the current directory (<cwd>/.environment.alliance.xml).
- New: DefParser, DefDriver & LefDriver are replaced by DefImport, DefExport
and LefExport (resp.). LEF/DEF parser/driver are no longer integrated
in among Alliance ones due to too much difference in data organisation.
Instead they are build as Import/Export utilities.
- New: Iccad04Lefdef import the ICCAD'04 benchmarks into the SxLib format
suitable for Knik/Kite. They are derived from the ISPD'98 (ibm01--ibm18)
benchmarks. Many corrections are applieds to ensure a more realistic
representation.
Generate a new library from the LEF file "on the fly".
- New: Ispd04Bookshelf import the ISPD'04 benchmarks in SxLib from bookshelf.
Thoses benchmarks can be placeds whith fastplace. Unfortunatly fastplace
do not manage blocks and reduce them to standard cell which is not
usable for detailed placement. Too bad, the parser exists still.
Make uses of the new vlsisapd/bookshelf parser. A whole library is
generated "on the fly" on the basis of "one node, one Cell" (so we have
a bijection between Cell and Instance). The result of this parsing is
different from the one of the stand-alone ispd04 binary in the sense it
fits the circuit to the SxLib gauge thus changing the routing capacity:
from 16 to 20.
- Change: In ApDriver, the lookup modify the lookup table for matching
Alliance layers against Hurricane ones, "OBSTACLEx" became "BLOCKAGEx".
- Change: In default <enviromnent.alliance.xml> adds the name of the
blockage net: "^obstacleNet$". Some work over the coherency of the
blockage managment remains to be done.
- Change: In AllianceFramework, partial rewrite of the get/creation of
AllianceLibrary to fit the requirements of the "on the fly" generation
from the benchmarks loaders. And correct some bugs by the way.
- Change: In Environment, suppress any reference to LEF technology as LEF/
DEF is now used as import/exports.
- Bug: In VstDriver, perform only one lookup for global signals among all
nets and not for each instance master cell. That was making the driver
quadratic! Now it's linear and reasonably fast.
- New: In Utilities, automatic setting of STRATUS_MAPPING_NAME. It's put
back into the environment from the configuration. This suppress the
need for the last environment variable under cgt.
- New: In <tools.configuration.xml>, added parameters for verbosity, info
and trace level.
- New: Uniform mecanism to get the "/etc" path. Now System reads the
environment variables (thanks to boost::program_option).
- Change: In Utility, correct "when first called" initialisation of the
System singleton. Access to members only through static members that
ensure the initialisation of the singleton first.
- Change: In System, makes uses of the callback feature of Parameter to
initialize the new configuration parameters (verbosity, coredump, ...).
- Change: In linefill, build upon mstream instead of ostream. Now dual
aspect, inherit ostream and have a mstream member.
