NAME SystemC::Manual - SystemPerl primary documentation SUMMARY The publicly licensed SystemPerl package provides several extensions to SystemC. It provides sp_preproc, extending the language for AUTOmatic connection of hierarchy 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.org/systemperl 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 hierarchy 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 SystemC::SystemPerl after installation. sp_include shows a technique for speeding up SystemC compiles using GCC. sp_makecheck allows for cleaning up dependency files when dependencies 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. You may point to this directory underneath the kit, or set SYSTEMPERL_INCLDUE to point to these sources. 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*/ This expands into: 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 SUPPORTED SYSTEMS This version of SystemPerl 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, 2.0.1, 2.1 and 2.2 are the versions supported for tracing, other versions should work without tracing or with minor editing. INSTALLATION * Download the latest package from http://www.veripool.org/systemperl or CPAN and decompress. gunzip SystemPerl_version.tar.gz ; tar xvf SystemPerl_version.tar} * cd to the directory containing this README notice. Some files will permanently live in this directory, so make sure it's in a site wide area. cd SystemPerl* * Make sure the "SYSTEMC" environment variable points to your SystemC installed directory. If using bash, this would consist of the line export SYSTEMC=/path/to/systemc in your "~/.bashrc" file. If different than the above, make sure the "SYSTEMC_KIT" environment variable points to your original SystemC source code kit. Type "perl Makefile.PL" to configure SystemPerl for your system. You may get a warning message about needing Verilog::Netlist, if so you need to install or upgrade the "verilog-perl" package from CPAN. * To trace sc_bv's, you must patch the SystemC library. Type as root "make sc_patch" and this will be done for you. What this does is add an accessor function for getting at the raw data in the sc_bv class. (Using the preexisting public functions would require too much computational overhead.) This will also patch SystemC to work with Redhat 9 distributions (GCC 3.2.2). If you were not able to compile SystemC due to compile errors, it may now work. * Type "make" to compile SystemPerl. If you get a error message ``y.tab.c: error: parse error before goto,'' there is a problem between Bison and GCC. The simplest fix is to edit y.tab.c to comment out ``__attribute__ ((unused))''. * Type "make test" to check the compilation. * 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. * Type "make install" to install the programs and any data files and documentation. * Add a "SYSTEMPERL" environment variable that points to the directory of this kit (the directory you typed ``make install'' inside, not your site-perl directory.) If using bash, this would consist of the line export SYSTEMPERL=/path/to/systemperl in your "~/.bashrc" file. * Optionally add a "SYSTEMPERL_INCLUDE" environment variable if for some reason you wish to relocate the include files. For example distributions often want to relocate the SystemPerl includes into the standard system include directory. DISTRIBUTION SystemPerl is part of the free SystemC software tool suite.
