Warnings

Safety Warnings for Periphery USART.
Safety warnings are related to the Requirements Layer, especially the SIL

USART has a SIL required of SIL_1 but a SIL achieved of QM

Requirements Model

Logical Function Model

Software Model

Hardware Model

Required
The highest SIL derived from SafetyRequirements and Technical Functions. SIL derived	SIL_1
This attribute allows to overwrite the derived SIL level. The result is the SIL effective attribute. SIL manual	derived
The reason why the derived SIL is ignored and an explicit SIL is set. reason
The SIL required for this implementation unit is defined by the derived SIL but can be overwritten by "SIL manual". SIL required	SIL_1
Achieved
The achieved SIL for this implementation unit. Has to be provided by the user. SIL achieved	QM
A justification why a certain SIL was achieved. justification

Base
The name of this object. Certain classes of objects require this field to be unique. Please consider that this field might be used in code and thus must not contain special characters. Name	USART
The type of this object within the uRTE model Type	Periphery
A descriptive text for this object. Please consider that this field might be used in code and thus must not contain special characters. Description	UART module connected to pin TX/RX PA2/PA3 at 115200 8N1
A user defined ID which can be freely chosen. Please consider that this field might be used in code and thus must not contain special characters. User-ID	Periphery_8
Each object within the uRTE model has a unique ID, this is the ID for this object UID	_OQXaQOTTEeyrV5NXTwe27Q
Addressing
The start-address of an addressable hardware-component. Start	USART2_BASE
The end-address of an addressable hardware-component. End	USART3_BASE - 1
