VciSimHelper

1) Functional Description

This VCI target is a synthetic component that can be used to instrument the simulation process. It can make the simulation stop, exit or crash different ways.

It has four mapped register accepting only writes.

Possible actions are:

• Make the simulator call sc_stop()
• Make the simulator call exit( val ), with a given val
• Make the simulator throw an exception with a given value in message
• Make the simulator pause (i.e. wait for a keyboard event)

Registers are:

• SIMHELPER_SC_STOP (at offset 0x0): Call sc_stop()
• SIMHELPER_END_WITH_RETVAL (at offset 0x4): Call exit(val)
• SIMHELPER_EXCEPT_WITH_VAL (at offset 0x8): Create a soclib::exception::RunTimeError("Simulation yielded error level "+val)
• SIMHELPER_PAUSE_SIM (at offset 0xc): Pause simulation

CABA Constructor parameters

VciSimhelper(
     sc_module_name name,   // Instance name
     const soclib::common::IntTab &index,   //  Target index
     const soclib::common::MappingTable &mt)   // Mapping Table

Example instanciation:

VciSimhelper simhelper("simhelper", 
               IntTab(2,3), 
               mapping_table );
