FwSmDesc_t GetCurCheckSm ( )

Retrieve the descriptor of the Current FD Check State Machine.

The Current FD Check State Machine is a singleton. The first time this function is called, it creates and configures the state machine descriptor. Subsequently, it always returns the same descriptor.

The Current FD Check State Machine is built as an extension of the generic FD Check State Machine (see FwDaFailDetCheck.h) with the following changes:

  • The Default Anomaly Detection Check (function DefAnomalyDetCheck) is overridden to report "anomaly detected" if the current absorbed by the hardware device is above HW_DEV_CUR_MAX_NOM.
  • The Default Recovery Action (function DefRecoveryAction) is overridden to send a switch-off command to the Hardware Device.
  • The counter limit cntLimit is set to HW_DEV_CUR_CNT_LIMIT.

Thus, this FD Check monitors the current absorbed by the Hardware Device and, if it finds that it is out-of-limits for more than HW_DEV_CUR_CNT_LIMIT consecutive cycles, it switches off the Hardware Device.

Returns
the descriptor of the FD Check State Machine or NULL if the state machine could not be created.
