Physical Architecture: OBC Watchdog Monitoring and Timeout

[xszymonzur]

Existing diagrams to extend:

• [PFBD] Root Physical Function Breakdown
• [PCBD] Root Physical Component Breakdown
• [PAB] Root Physical Architecture

New diagrams to create:

• [ES] OBC Watchdog Monitoring Scenario, Healthy MCU Scenario:
  • kicking watchdog when needed
  • restarting timers
• [ES] OBC Watchdog Monitoring Scenario, Watchdog Timeout Scenario:
  • failure detection through hardware watchdog timeout
  • OBC hard reset by watchdog
  • kicking watchdog before subsequent timeout
• (Optional) [PDFB] Functional Dataflow View of OBC Watchdog Monitoring Scenario
• (Optional) [PAB] Physical Architecture View of OBC Watchdog Monitoring Scenario
