SystemC::Manual - SystemPerl primary documentation


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


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,

    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) {
        SC_CTOR(mod) {
            SP_CELL (sub, submod);

This expands into:

    SC_MODULE(mod) {
        // Beginning of SystemPerl automatic signals
        sc_signal<bool>             a;       // For submod
        // End of SystemPerl automatic signals

        SC_CTOR(mod) {
            SP_CELL (sub, submod);
            // Beginning of SystemPerl automatic pins
            SP_PIN (sub, a,       a);
            // End of SystemPerl automatic pins


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.



SystemPerl is part of the http://www.veripool.org/ free SystemC software tool suite. The latest version is available from CPAN and from http://www.veripool.org/systemperl.
