- 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 LefExport, export the spacer cells (rowend & tie) to enable
filling in Cadence Encounter.
- New: In DefImport, added support for regular wiring in NETS. Allows us
to import routing from Encounter and characterize it.
- New: In Catalog, added a CatalogExtension static property manager to
allow more easy access to the Catalog::State of each Cell. Do not
uses the default template because of a specific destructor and a
"by pointer" value.
- 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.
+ change cmake OpenAccess macro we need 2 env variables :
OA_LIB_DIR where are the oa libs
OA_INCLUDE_DIR where are the oa headers
this way different headers version can be tested versus different OA compiled libs
- New: Added support for ACM/SIGDA ISCAS98 (.bench extension).
- Bug: In Parsers/Drivers changes the signature of the prototype, passes
file name string by value instead of by reference. In the cases of
reentrant P&D calls it may causes havoc.
- 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.
- 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.
* ./crlcore:
- In PyCRL, module method "getAllianceFramework()" moved as static object
method "get()" of AllianceFramework. Object AllianceFramework added
to module CRL.
cleaner separated functions converting Hurricane objects to oa
create 4 "Design CellView" of the cell : netlist, symbol, schematic and layout
remove bug with oaLib or oaTech at openning
adding oaLayerConstraint in oaLayer from the oaTech for the rule of the technology
