The contributors that suggested a given feature is shown in [].
This uses outline mode in Emacs. See C-h m [M-x describe-mode].
* Changes in SystemC 1.140 4/6/2003
*** Allow "sp use DEFINE" where DEFINE is a symbol like ALIAS_CELL
that should be replaced with the definition value of ALIAS_CELL.
*** Support tracing AUTOENUM types. [Greg Waters]
**** Report warning if SP_TRACED variables aren't traced. [Greg Waters]
**** Allow enum values to initialize to symbolic constants. [Greg Waters]
**** Use low level I/O routines to improve tracing by 30%.
**** Have AUTOTRACE use values from the module that generates the signal
rather then the top level. With Verilator, tracing is 10% faster.
**** Support bison 1.75
* Changes in SystemC 1.130 11/3/2002
** Support SystemC version 2.0.1. A patch is required for tracing
input signals and sc_bv types, see the the README file.
*** Add example of SP_COVER statement.
* Changes in SystemC 1.122 8/29/2002
*** Put AUTOINOUT signals under that label, so they can be public
while AUTOSIGNALs can be private. [Greg Waters]
*** Support signals in inherited sc_modules. [Navit Fedida]
* Changes in SystemC 1.120 8/19/2002
*** Support modules declared as inherited from sc_module. [Navit Fedida]
* Changes in SystemC 1.110 8/8/2002
**** Allow traced modules to determine if they might have any activity.
Used for Verilator3 to improve trace speed by about 60%.
* Changes in SystemC 1.100 3/11/2002
** Added Emacs mode in systemc-mode.el
** Added #sp use "filename", for determining link objects automatically.
*** Allow modules not specified on the command line to be found
automatically by using the search path (ala Verilog.)
**** SystemC::Parser now emits a separate text() callback for the text
of a AUTO. This allows programs to more easily replace the text inline.
**** Improve tracing to allow smaller files, rollover, inlining child traces.
* Changes in SystemC 1.000 11/16/2001
** Moved Netlist guts into Verilog package,
made SystemC a derrived class. This allows mixed-mode netlists.
** $SYSTEMPERL should now point to the root of this package,
not the root/src directory.
*** Include header guards in .cpp file so that multiple CONCAT
inclusions with sp_includer work OK.
*** Allow tracing of sc_bv<>'s
**** Addition of experimental sclite library
for testing package without SystemC installed.
* Changes in SystemC 0.430 9/26/2001
** Added #sp include directive. [Experimental, some crashes]
** AUTOMETHODS is the new name for AUTODECLS
AUTOMETHODS will create a SC_CTOR(__MODULE__); if there is not
already one in the class interface.
** AUTOTRACE uses a internal library to trace ports.
AUTOTRACE should work on all clocks, ports, arrays, etc, and
any simple types marked with SP_TRACED.
AUTOTRACE requires AUTOMETHODS to be used in the class interface.
** The #include systemperl.h at the top of all .h files has been removed.
It must be included manually. This allows systemperl to be used in
non-systemc applications.
*** AUTOENUM ascii() method implementations are now put in the .cpp
rather then the .h file. This is indicated by a AUTOIMPLEMENTATION
section, which is inserted automatically at the bottom of the .cpp
file if not elsewhere in the file.
*** Detect and report unterminated strings, automodes, comment blocks.
*** Handle character constants ('a', '\0'). Handle octal and hex
escape sequences in strings and char-constants.
*** Handle nested typenames (e.g. sc_out<ClassFoo::EnumBar>).
* Changes in SystemC 0.420 6/27/2001
** Added AUTOSUBCELL_INCLUDE and AUTOSUBCELL_CLASS
** Extracted SystemC::Template for other programs needing #line'd files.
** Comments are now properly extracted for signals & ports.
Note such comments must begin on the same line as the declaration.
*** Fixed extra #line statements in output files.
*** Added directional comment to /*AUTOINST*/ created pins.
*** Fixed bug with recognizing sc_inouts. [Amir Sahar]
* Changes in SystemC 0.410 5/21/2001
** Added AUTOTRACE for creating trace statements for all signals.
** Added sp_includer and sp_makecheck for faster SystemC compiles.
*** Added sp_preproc --libcell for cells that are not to be expanded.
This is useful for hierarchical sp_preproc'essing.
* Changes in SystemC 0.400 5/4/2001
** Added AUTOENUM_* for ascii displays of enum values.
** Added SP_CTOR_IMP for constructors outside of the class decl.
** Added SP_CELL_DECL, and allowed arrayed cell declarations.
** Added SP_CELL_FORM for printf formatting of cell name.
** Fixed class x {enum y}, class z {enum y} problem.
*** Fixed test on Solaris Linux.
**** The debugging dump methods are now ->dump, not ->print.
* Changes in SystemC 0.300 4/3/2001
** sc_clocks are now recognized as signal declarations.
** sc_main is considered similar to a SC_MODULE(sc_main)
**** Support Perl 5.005_003 and non-GCC
**** Many, Many bug fixes.
* Changes in SystemC 0.1 3/31/2001
**** Package Created
