+The [source:soft/giet_vm/giet_drivers/sim_driver.c sim_driver.c] and [source:soft/giet_vm/giet_drivers/sim_driver.h sim_driver.h] files define the SIM driver. 
+
+This driver supports the vci_sim_helper component, that is a pseudo hardware component available in the SoCLib library, and providing a monitoring service in a virtual prototyping environment.
+
+There is at most one such component in the architecture.
+
+The SEG_SIM_BASE address must be defined in the hard_config.h file.
+
+The addressable registers map, defining the possible operations is defined [source:soft/giet_vm/giet_drivers/sim_driver.h here].
+
+ === void '''_sim_helper_access'''( unsigned int  register_index,  unsigned int  value,  unsigned int* retval ); 
+This function accesses the Simulation Helper registers:
+ * If access is on  SIMHELPER_SC_STOP, the simulation will stop.
+ * If access is on  SIMHELPER_CYCLES, value is written in retval buffer.
