This is the SystemC Perl Package, aka SystemPerl. Copyright ========= This package is Copyright 2001 by Wilson Snyder .

It provides sp_preproc, extending the language for AUTOmatic connection of hiearchy like my Verilog-Mode, trace files and netlist linting. Its netlist and parsing utilities are general enough for writing your own tools. Two additional tools provide for speeding up GCC compiles and dependency correction. You can download SystemC from the link off of http://www.veripool.com/systemperl.html Description =========== This package provides several major sub-packages. The SystemC::Parser understands how to read SystemC files, and extract tokens and such, similar to Verilog::Parser. SystemC::Netlist builds netlists out of SystemC files. This allows easy scripts to determine things such as the hiearchy of SC_MODULEs. The netlist database may also be extended to support other languages. sp_preproc provides extensions to the SystemC language, called the SystemPerl language. This allows most of the Tedium to be removed from SystemC coding, just as the author's /*AUTO*/ comments did for the Verilog language. See `man SystemPerl' after installation. sp_include shows a technique for speeding up SystemC compiles using GCC. sp_makecheck allows for cleaning up dependency files when dependancies have been removed or changed. Finally, the src directory contains useful C++ utilities for simulation, such as changing cout to send to both the screen and a file. Parsing example: package Trialparser; @ISA = qw(SystemC::Parser); sub module { my $self = shift; my $module = shift; print $self->filename.":".$self->lineno().": "; print "Contains the module declaration for $module\n"; } package main; my $sp = Trialparser->new(); $sp->read ("test.sp"); Netlist example: use SystemC::Netlist; my $nl = new SystemC::Netlist (); foreach my $file ('testnetlist.sp') { $nl->read_file (filename=>$file, strip_autos=>1); } $nl->link(); $nl->autos(); $nl->lint(); $nl->exit_if_error(); foreach my $mod ($nl->modules_sorted) { show_hier ($mod, " "); } sub show_hier { my $mod = shift; my $indent = shift; print $indent,"Module ",$mod->name,"\n"; foreach my $cell ($mod->cells_sorted) { show_hier ($cell->submod, $indent." ".$cell->name." "); } } SystemPerl Example ================== SC_MODULE(mod) { /*AUTOSIGNAL*/ SC_CTOR(mod) { SP_CELL (sub, submod); /*AUTOINST*/ Becomes: SC_MODULE(mod) { /*AUTOSIGNAL*/ // Beginning of SystemPerl automatic signals sc_signal a; // For submod // End of SystemPerl automatic signals SC_CTOR(mod) { SP_CELL (sub, submod); /*AUTOINST*/ // Beginning of SystemPerl automatic pins SP_PIN (sub, a, a); // End of SystemPerl automatic pins Obtaining Distribution ====================== The latest version is available at `http://www.perl.org/CPAN/' Download the latest package from that site, and decompress. `gunzip SystemPerl_version.tar.gz ; tar xvf SystemPerl_version.tar' Supported Systems ================= This version of SystemC has been built and tested on: * i386-linux It should run on any system with Perl, a C compiler, bison, and flex. SystemC must be installed to get the complete function. Currently 1.2.1beta is the version supported for tracing, other versions should work without tracing. Installation ============ 1. `cd' to the directory containing this README notice. 2. Type `perl Makefile.PL' to configure SystemC for your system. (Note this package will probably run slower if you are still using perl 5.005.) 3. Type `make' to compile SystemC. 4. Type `make test' to check the compilation. 5. You can see examples under the test_dir directory. The *.sp files are "inline" converted, while the *.h and *.cpp files are expanded from the .sp files. 6. Type `make install' to install the programs and any data files and documentation. 7. Install `src/systemperl.h' somewhere in your project's build path. The best place is probably the $SYSTEMC/include directory. 8. If you wish to trace ports, you must edit the SystemC library. Search the header files for "get_cur_value", and add a public: declaration before it. After doing so, create a $SYSTEMC/systemperl_patched file. (SystemPerl will see this file and allow port tracing.)
