clock_synch¶
The clock synchronization module is used to slave the simulation to realtime. The module is controlled by specifying an acceleration factor which can be adjusted dynamically if the timeInitialized factor is also reset dynamically.
-
class
ClockSynch: public SysModel¶ Public Functions
-
ClockSynch()¶ This is the constructor for the clock synch model. It sets default variable values and initializes the various parts of the model
-
~ClockSynch()¶ Destructor. Nothing here.
-
void
SelfInit()¶ This is the self-init routine for the clock synch model. It initializes the output message for the model which is used for diagnostic information on the model’s behavior.
- Return
void
-
void
CrossInit()¶ This method is blank but included in case we need to add functionality to the model.
- Return
void
-
void
Reset(uint64_t currentSimNanos)¶ Reset the module variables.
- Return
void
-
void
UpdateState(uint64_t currentSimNanos)¶ This method performs all of the runtime behavior for the clock synch model. It initializes the timers present in the model on the first pass and then ensures that the model stays stuck on the synchronization pulse. Note that we do the init on the first pass instead of the init routines so that we don’t have a big lag between initialization and runtime which messes up our clocking.
- Return
void
- Parameters
CurrentSimNanos: The clock time associated with the model call
