Overview
The Safe Watchdog Interface (S-WdgIf) is the middle layer of the Safe Watchdog Manager Stack. The
Safe Watchdog Manager Stack is part of the service layer of the AUTOSAR architecture. The Safe
Watchdog Interface abstracts one or more Safe Watchdog Driver modules for the Safe Watchdog Manager
module.

The Safe Watchdog Interface consists of
  embedded software module and
  configuration generator.

The Safe Watchdog Interface is compatible to the WdgIf module as specified in the AUTOSAR 4.0 and
AUTOSAR 3.1 specifications but not fully compliant. For deviations and justifications please see the S-WdgIf
User Manual.
