[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 than the top level. With Verilator, tracing is 10% faster. **** Support bison 1.75 * SystemC 1.130 2002/11/3 ** 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. * SystemC 1.122 2002/8/29 *** 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] * SystemC 1.120 2002/8/19 *** Support modules declared as inherited from sc_module. [Navit Fedida] * SystemC 1.110 2002/8/8 **** Allow traced modules to determine if they might have any activity. Used for Verilator3 to improve trace speed by about 60%. * SystemC 1.100 2002/3/11 ** 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. * SystemC 1.000 2001/11/16 ** Moved Netlist guts into Verilog package, made SystemC a derived 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. * SystemC 0.430 2001/9/26 ** 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 than 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). * SystemC 0.420 2001/6/27 ** 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] * SystemC 0.410 2001/5/21 ** 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. * SystemC 0.400 2001/5/4 ** 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. * SystemC 0.300 2001/4/3 ** 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. * SystemC 0.1 2001/3/31 **** Package Created ---------------------------------------------------------------------- $Id: Changes 49154 2008-01-02 14:22:02Z wsnyder $ DESCRIPTION: Documentation on change history for this package ---------------------------------------------------------------------- This uses outline mode in Emacs.
