SystemCASS is a library you have to link with your hardware description in SystemC language. When you run the simulation, SystemCASS extracts options starting with -- :

General

• --usage : print simulation performance (cycle per second) at the simulation end
• --help : print available options
• --nobanner : do not print SystemCASS splash screen
• --nodynamiclink : do not link dynamically scheduling code
• --nosim : run until elaboration stage. Don't simulate
• --v : print internal SystemCASS kernel options (stderr)

Tracing

• --tracestart n : start tracing functions at #n cycle
• --notrace : disable all tracing functions (sc_trace). Usefull to gain a significant simulation speed up

Debug

• --i : print all the sc_module instances, and all the sc_signal signals
• --c : print schedule at simulation time (stderr)
• --d : check port dependencies (stderr)
• --f : print function list (stderr)
• --modules filename : dump module hierarchy graph into specified dot file (tons of bugs inside)

Scheduling

• --t : dump signal dependency or module dependency graph into a dot file
• --edit : edit schedule before simulation (run $EDITOR or vim by default)
• --a : use almost static scheduling (use sensitivity list instead of port dependency information) [default]
• --m : use Mouchard's static scheduling (use port dependency information instead of sensitivity list)
• --p : use entirely static scheduling (use port dependency information instead of sensitivity list) [best scheduling method]
• --c : print scheduling at run/simulation time (stderr)

Other

• save_on_exit <name> : save simulation state saved into <name> file when SystemCASS exits (SOCVIEW format)

Examples :

system.x --t --tracestart 1000000
