Emulation State-Transition Diagrams

Some initial state-transition diagrams for some IP blocks. Very much rough sketches/brainstorms and not finalized ideas.

100Gb Ethernet MAC

@startuml EmulatorStateTransitionDiagramMAC NO_LINK : MAC is not receiving any packets. LINK : MAC is receiving and processing packets. DEGRADED : MAC is receiving packets with errored bits. FAULT : A critical fault condition has occurred. [*] --> NO_LINK : Power on NO_LINK --> LINK : Packets received LINK --> DEGRADED : Errored packets received DEGRADED --> LINK : Received packets no longer errored LINK --> NO_LINK : Packet flow stopped DEGRADED --> NO_LINK : Packet flow stopped DEGRADED --> FAULT : Critical fault note top of FAULT Does MAC need a distinct FAULT state, or is DEGRADED sufficient? end note FAULT --> [*] @enduml

Wideband Input Buffer

@startuml EmulatorStateTransitionDiagramWIB RESET : WIB has been powered on and not yet configured. state " " as active { CONFIGURING : WIB is being configured. READY : WIB has been configured and is ready to be enabled. ENABLING : WIB is being enabled. ENABLED : WIB is enabled and processing and outputting data. FAULT : A critical fault condition has occurred. } [*] --> RESET : Power on active -up-> RESET : Power cycle RESET --> CONFIGURING : Configure CONFIGURING --> READY : Done configuring READY --> ENABLING : Enable READY -right-> FAULT : Critical fault ENABLING --> ENABLED : Done enabling ENABLING -right-> FAULT : Critical fault ENABLED --> READY : Disable ENABLED -right-> FAULT : Critical fault FAULT --> [*] @enduml

Very Coarse Channelizer

@startuml EmulatorStateTransitionDiagramVcc20 RESET : VCC has been powered on and not yet configured. state " " as active { CONFIGURING : VCC is being configured. READY : VCC has been configured and is ready to be enabled. ENABLING : VCC is being enabled. ENABLED : VCC is enabled and processing and outputting data. FAULT : A critical fault condition has occurred. } [*] --> RESET : Power on active -up-> RESET : Power cycle RESET --> CONFIGURING : Configure CONFIGURING --> READY : Done configuring READY --> ENABLING : Enable READY -right-> FAULT : Critical fault ENABLING --> ENABLED : Done enabling ENABLING -right-> FAULT : Critical fault ENABLED --> READY : Disable ENABLED -right-> FAULT : Critical fault FAULT --> [*] @enduml
