Overview
The Safe Watchdog Manager (S-WdgM) is upper software layer of the Safe Watchdog Manager Stack.
The S-WdgM Stack is part of the service layer of the AUTOSAR architecture. The S-WdgM monitors the
program flow and timing constrains of so-called Supervised Entities. When it detects a violation of the pre-
configured program flow and timing values, it takes a number of configurable actions to recover from this
state.

The Safe Watchdog Manager Stack consists of the following embedded software modules:
  Safe Watchdog Manager software module (hardware independent)
  Safe Watchdog Interface software module (hardware independent)
  Safe Watchdog Driver software module (hardware dependent),

and the Safe Watchdog Manager Stack configuration generators:
  Safe Watchdog Manager configuration generator (hardware independent)
  Safe Watchdog Interface configuration generator (hardware independent)
  Safe Watchdog Driver configuration generator (hardware dependent)

and the Safe Watchdog Manager Stack configuration verifier
  Safe Watchdog Manager configuration verifier (hardware independent)

This document represents the release notes for the Safe Watchdog Manager module only.

The Safe Watchdog Manager is compatible to the WdgM 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-
WdgM User Manual.

`WdgM_PBcfg.h` shall #include `WdgM_Cfg.h`
S
The issue description (issue69689):
The file `WdgM_PBcfg.h` uses a type `WdgM_ConfigType` but does not #include the header file where that
type is defined. This situation causes normally no problems because the corresponding C source file
`WdgM_PBcfg.h` has the following #include directive:
  #include "WdgM.h"
  #include "WdgM_PBcfg.h"
Where "WdgM.h" includes the necessary `WdgM_Cfg.h`.

The current release improved this point and the `WdgM_PBcfg.h` includes the `WdgM_Cfg.h` directly.

S-WdgM module was not changed in this release, the Safety Case document was added only.

The change description (issue68941):
The cross-cutting checks are removed from S-WdgM Generator. The Watchdog Manager
Config Generator should not attempt to verify the Watchdog Driver's data because this is on this level not
necessary. The removed cross-check parameters are the following:
  WdgGeneral/WdgInitialTimeout
  WdgSettingsConfig/WdgWindowStart
  WdgSettingsConfig/WdgSlowModeMax
  WdgSettingsConfig/WdgFastModeMax

  For the global Disable/Enable interrupts the AUTOSAR Schedule Manager interface is now used
instead of the operating system interface. (Now the SchM_WdgM.h needs to be included)
  When the RTE is used, then the S-WdgM uses the defines and typedefs generated by RTE instead
of the S-WdgM internal typedefs and defines (switchable with WDGM_USE_RTE)
  Primary Reset path instead of Secondary reset path is used when the
WDGM_IMMEDIATE_RESET==STD_ON is selected. This change was done to guarantee safe
reset. (The previously used external Mcu_PerformReset() function is a QM function)
  The Timebase Tick counter check (stuck-in and negative count) was corrected in the
WdgM_MainFunction()
  Similar to the S-WdgM the S-Wdg has now a Wdg_MemMap.h file. So it is possible to place the
Wdg variables to a memory section predefined by DaVinci Configurator.
Generators:
  better error handling
  XSLT Stylesheet now includes `WdgM_MainFunction` and `WdgM_UpdateTickCount` as runnables.
  Drivers/platforms now can be identified correctly regardless of the SHORT-NAMEs chosen by users

ECU description file change:
Release 1.2.0 uses SUB-PACKAGEs for organizing platform-related data inside ECU description file.
ECU description files created for previous versions have to be adapted slightly - otherwise the code
generators may not be able to find the platform data.  Please follow these steps:

1.  Open the ECU Description file with a text editor
2.  Find <DEFINITION-REF> elements in the ECU description file containing `/TTTECH/Wdg` or
`/TTTECH/WdgImpl`
3.  Replace the `TTTECH/Wdg` substring with `TTTech/TMS570LS3x/Wdg` and /TTTECH/WdgImpl`
with /TTTECH/TMS570LS3x/WdgImpl`
4.  Save your changes

3.28  Changes with Release 1.1.0: WdgM Subpackage 1.1.0
Embedded code:
  The AUTOSAR 3.1 functionality Deactivate / Activate entity was implemented.
  The Callback Notification was implemented.
  The entities initialization in the WdgM_Init() was corrected.
  The Timebase Tick overrun correction was removed on places where it wasn’t necessary
  The MPC5604B Safe Watchdog driver was implemented
o  Note: the MPC5604B internal watchdog’s registers (module SWT) can only be accessed in
one of the supervisor modes. This means that the WdgM_MainFunction(), which periodically
triggers the watchdog, must run in a supervisor mode!
o  This first version of the MPC5604B Safe Watchdog driver was developed and tested using
the Freescale CodeWarrior Compiler 5.9.0.
o  Following configuration sets were verified: fSIRCkhz=128, interruptThenReset=false,
hardLock=false, stopModeControl=true, debugModeControl=true, WdgDevErrorDetect=true,
WdgDemReport=true, WdgDisableAllowed=true, WdgVersionInfoApi=true.

Generators:

callback notifications.
Wdg_If_Cfg_Gen.exe generates code for the MPC5604B driver and corresponding interface.
3.29  Changes with Release 1.0.0: WdgM Subpackage 1.0.0
  The Safe Watchdog Interface embedded code was split in to two modules:
1.  Safe Watchdog  Interface, is now hardware independent
2.  Safe Watchdog Driver, is hardware dependent
  The Mode switch through the WdgM_Init was removed.
  There is now possibility to disable interrupts while the Global shared data are manipulated
  Some enum definitions in the S-WdgM API (like LOCAL_STATUS_OK) was changed to AUTOSAR
specified #defines
  Changes in the generators:
  The generators generates now additionally WdgM_Cfg_Features.h,WdgIf_Cfg_Features.h,
Wdg_TMS570LS3x_Cfg_Features.h files.
  The generators generates now additionally WdgM_MemMap.f file.
  Changes in the bswmd and swc files:
  Feature definitions are added (defined in the …Cfg_Features.h files)
  Software version and vendor info was added
  Obsolete 3.1 items was deleted
  DEFINITION-REF elements now contains paths beginning with TTTECH instead of AUTOSAR
  The bswmd files are now schema compliant.
  At typedefs WdgM_CheckpointIdType,  WdgM_SupervisedEntityIdType was the maximum value
changed to 65535.

Known issues, limitations, updates
Known issues:
For known issues please see the chapter “Change history” above.

Functional limitations of current version:
Not known.

Updates:
Current release represents a S-WdgM module for AUTOSAR 4.0.x and AUTOSAR 3.1.y.

Note, that the S-WdgM Configuration generator reads the AUTOSAR version from ECU description file and
generates a define “#define WDGM_AUTOSAR_4_x STD_ON” in case of Autosar 4.x. Dependent on this
define the embedded code uses the appropriate Autosar 4.0.x functionality.
