Platform Compilation

Prerequisites

We'll assume your configuration file is valid.

In order to compile a platform with soclib-cc, you need:

• Your top-cell SystemC netlist,
• A platform description file, listing all used components and their parameters.

Your top-cell file should

• Include all soclib component definitions
  • Paths are relative to systemc/include
• Define a sc_main,
• Create the components, signals, ...
• Connect them
• Run simulation.

Your platform description should be a python-parseable file, defining variable todo, instance of type Platform. Arguments passed to Platform are the used components, and you custom files (You may want to link in more than one custom .cc file).

Example

I will only use a mapping table, instanciate it, and compile a platform:

File top.cc:

#include <iostream>
#include <systemc.h>
#include "mapping_table.h"

int sc_main(int argc, char **argv)
{
    using soclib::common::IntTab;
    using soclib::common::MappingTable;
    using soclib::common::Segment;

    MappingTable mt(32, IntTab(2), IntTab(2), 0x300000);
    mt.add( Segment("reset", 0xbfc00000, 0x800,  IntTab(0), true) );
    mt.add( Segment("excep", 0x80000080, 0x100,  IntTab(0), true) );
    mt.add( Segment("data",  0x40000000, 0x4000, IntTab(1), true) );
    mt.add( Segment("code",  0x04000000, 0x4000, IntTab(2), true) );

    std::cout
        << "Mapping table is:" << std::endl
        << mt << std::endl;
    return 0;
}

File platform_desc:

todo = Platform('caba', 'top.cc',
				uses = [
        Uses('common:mapping_table'),
    ])

Now the compilation:

$ soclib-cc -p platform_desc

CxxLink link system.x
$ 

And running:

$ ./system.x
