# 用語(terms)
|Term|Description|Example|
|:--|:--|:--|
|Class|A class represents a kind of electrical connection to the ECU. It could be for example an analogue, a discrete,… |Analogue Class, Discrete Class…
|Electrical Signal|It is the electrical signal on the pin of the ECU |Physical input voltage at an ECUPin
|ECU pin| It is an hardware electrical connection of the ECU with the rest of the electronic system
|ECU Signals|It is the software representation of an electrical signal. A signal has attributes and a symbolic name |Input voltage,Discrete Output, PWM Input …
|ECU Signal group|It is the software representation of a group of electrical signals from the same Class|Only for discrete Inputs and discrete Outputs
|Attributes|Characteristics that can be Software (SW) and Hardware (HW) for each kind of Signals existing in a ECU |Range, Lifetime / delay, …
|Symbolic name| The symbolic name of a signal is used by the IO Hardware Abstraction module to make a link (function, pin)
|Data Type|Analogue: Datatype of the signal Discrete: either bool or AUTOSAR defined type (BoolType) |(VoltageType, CurrentType, ResistanceType, BoolType) Each DataType has a given size: 16 bits or 32 bits
|Range |This is a functional range and not an electrical range.) For analogue signals [lowerLimit...upperLimit] (Voltage, current), [0...upperLimit] (resistance) For discrete signals [0,1] For timing signals [0…upperLimit] (period), [- 100…100%] (Duty Cycle)|[-12Volts...+12Volts] (voltage)
|Resolution|This attribute for many Classes is dependent on the range and the Data Type. Example: (upperLimit - lowerLimit) / (2datatypelength -1) For the others is known and defined. |Voltagemin = -12 Volts Voltagemax = 12 Volts Data Type : 16 bits Resolution => 24 / 65535
|Hardware Resolution|This is the maximum possible resolution of the hardware (ADC) |ADC converter could have a 8/10/12/16 bits resolution
|Hardware Accuracy|This is the accuracy of Hardware. It depends on hardware peripheral used for acquisition and/or generation |ADC converter could have an accuracy of +-3LSB
|Accuracy| It depends of hardware peripheral used for acquisition and/or generation. |ADC converter could be a a 8/10/12/16 bits converter
|Diagnosis|Diagnosis capability of the functionality |Diagnosis Not Supported (could be a static check) No valid information available Short to Power Supply Short to Ground Open Load Over Temperature Diagnosis OK
|Synchronization| A signal could be synchronize with another signal or with an event like a trigger|If a discrete signal is “TRUE”, acquire an analogue signal
|Access |Defines if the Signal is attached to a Get(Read) / Set(Write) feature.
|Inversion|Inversion between the physical value and the logical value. This attribute is not visible and not configurable by users of IO Hardware Abstraction. |Physical HighState -> (Signal=False) Physical LowState -> (Signal=True)
|Lifetime| Only for Inputs: It is the maximum allowed age of the data (time is in microseconds). If Lifetime is 0, then the signal is directly get from the register. |Lifetime = 0 is a direct access Lifetime = 1000µs the value read is at maximum 1ms older
|Delay|Only for Outputs: It is the maximum allowed time until an output is actually set (time is in microseconds) If Delay is 0, then the signal is set immediately|Delay = 0 is a direct access Delay = 100µs the command is set until 100µs elapse
|Filtering /Debouncing|It defines if the Signal is provided as a raw value or if a filtering/debouncing method is included in the IO Hardware Abstraction module for this Signal.|Raw, Debounce 3 Samples, Wait 10ms,
|Sampling Rate| Time period required to get a Signal value. |Sampling rate for a sampling windows (burst)
|Report Changes|This attribute is only applicable to Discrete Inputs. It defines the capability (or not) of reporting level changes.|Enable or Disable
|Pulse Test| This attribute means that the output shall be|tested thanks a dedicated pulse. If this attribute is not set, diagnosis will be done while using the output.|Available or non available
