In CRL Core, the layout of the files under "/coriolis2/etc" changes.
Instead of having them directly under "etc", they are now replicated,
in subdirectories. Each subdirectory having the name of the associated
symbolic or real technology (they are kept separated). We have, for
now:
* etc/cmos/ : symbolic, the Alliance original one.
* etc/vsc200/ : symbolic, for G. Petley vsclib.
* etc/hcmos9/ : real, generic fake (130nm).
To tell which pair (symbolic,real) technologies must be used we create
a *second* (sigh) configuration file "coriolis2_techno.conf", and it's
hidden counterpart in the user's account, to set it up. It needs to be
separate because it is read as early as possible and select which set
of configuration files would be read.
Also add support up to METAL8 and POLY2 in CRL core and it's Alliance
parser/drivers.
- New: In Environment, adds a method getLIBRARYPath() to directly access the
path of an element in the SearchPath. Also added to the Python interface.
This is a quick alternative to fully export SearchPath and it's element
into the Python interface.
- A complete sweep of cleanup to suppress allmost all compiler warnings.
* ./crlcore:
- New: Extented Python support for all objects needed to configure Coriolis.
- New: Configuration files and load helpers completly written in Python.
An XML emulation mode is still avalaible.
- New: UsersGuide, as a replacement for README, written in ReST.
- New: Start of Doxygen documentation (mostly for documenting the initialisation
objects & methods).
- 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: 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.
- 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 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: 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.
- Change: adopt a tree layout compliant with the UNIX FHS.
* includes under TOP/include/coriolis2.
* shared datas under TOP/shared/coriolis2.
* docs under TOP/share/doc/coriolis2.
* configuration under TOP/etc/coriolis2
* ./crlcore:
- Change: In Environment, comply to the new tree layout, search configuration
files under TOP/etc/coriolis2/.
* ./knik:
- Change: In flute, comply to the new tree layout, get the "POW*.dat" files
from TOP/share/coriolis2/flute-2.4.
- Cleanup: No longer import the std namespace in headers.
- Bug: In Measures.h, incoherent prototyping of getMeasure() template.
- Change: In Environment, SearchPath & the XML format, slight change to
allow overwriting of Alliance library pathes. Instead of having an
attribute on the <system> node that applies to all libraries, we
have a "mode" attribute in each <library> node.
"mode" can takes three values:
1. - "append" : the library path is added in tail of the list.
2. - "prepend" : the library path is added in head of the list.
3. - "replace" : if the library already exists in the pathes,
this ones replaces it, whitout modifiying the order.
If it doesn't exists, it simply appended.
The "replace" mode is the one to be used if a users wants to shadow
system libraries by his own versions (sets in ~/.environment.alliance.xml).

- SVN MOVE: Source tree simplification & uniformisation. Now all tools
are at the same level, directly under the root of the repository.
No more "coriolis/src".
