文書変更(Document Change)

Changed SWS_IoHwAb_00145 to SWS_IoHwAb_NA_00145

用語(terms)

Expression	Description	Example
AUTOSAR	AUTomotive Open System ARchitecture
API	Application Programming Interface
BSW	Basic SoftWare
BSWMD	Basic SoftWare Module Description
C/S	Client/Server
DET	Default Error Tracer
ECU	Electronic Control Unit
HW	HardWare
IoHwAb	Input/Output Hardware Abstraction
ISR	Interrupt Service Routine
MCAL	MicroController Abstraction Layer
OS	Operating System
RTE	RunTime Environment
S/R	Sender/Receiver
SW	SoftWare
SWC	SoftWare Component (see [8] for further information)
XML	eXtensible Markup Language
Callback	Within this document, the term ‘callback’ is used for API services, which are intended for notifications to other BSW modules.
Callout	Callouts are function stubs, which can be filled at configuration time, with the purpose to add functionality to the module that provides the callout.
Class	A class represents a set of signals that has similar electrical characteristics.	Analogue class, Discrete class, …
Client / Server communication	This definition is an extract from [9]: Client-server communication involves two entities, the client which is the requirer (or user) of a service and the server that provides the service. The client initiates the communication, requesting that the server performs a service, transferring a parameter set if necessary. The server, in the form of the RTE, waits for incoming communication requests from a client, performs the requested service and dispatches a response to the client's request. So, the direction of initiation is used to categorize whether an AUTOSAR Software Component is a client or a server.
Electrical Signal	An electrical signal is the physical signal on the pin of the ECU.	Physical input voltage at an ECU-Pin
ECU pin	An ECU pin is an electrical hardware connection of the ECU with the rest of the electronic system.
ECU Signal	An ECU Signal is the software representation of an electrical signal. An ECU signal has attributes and a symbolic name	Input voltage ,Discrete Output, PWM Input
ECU Signal Group	An ECU Signal Group is the software representation Specification of I/O Hardware Abstraction of a group of electrical signals.
Attributes	Characteristics that can be Software (SW) and Hardware (HW) for each kind of ECU signals existing in an ECU. Some of the Attributes are fixed by the port definitions, others can be configured in the I/O Hardware Abstraction.	Range, Lifetime / delay
Sender-receiver communication	This definition is an extract from [9]: Sender-receiver communication involves the transmission and reception of signals consisting of atomic data elements that are sent by one component and received by one or more components. A senderreceiver interface can contain multiple data elements. Sender-receiver communication is one-way - any reply sent by the receiver is sent as a separate senderreceiver communication. A port of a component that requires an AUTOSAR sender-receiver interface can read the data elements described in the interface and a port that provides the interface can write the data elements.
Symbolic name	The symbolic name of a ECU signal is used by the I/O Hardware Abstraction to make a link (function, pin)
Range	This is a functional range and not an electrical range. All the range is used either for functional needs or for diagnosis detections For analogue ECU signals [lowerLimit...upperLimit] (Voltage, current). For the particular case of a resistance signal and a timing signal (period), the lowerLimit value can not be negative.	[-12Volts...+12Volts] (voltage) [0,1] (discrete signals) [0…upperLimit] (period timing signal) [-100…100%] (Duty Cycle based timing signal)
Resolution	This attribute is for many Classes dependent on the range and the Data Type.Example: (upperLimit - lowerLimit) / (2datatypelength -1) For the others classes, it is known and defined.	[-12 Volts…+12Volts] Data Type : 16 bits Resolution => 24 / 65535
Accuracy	It depends of hardware peripheral used for acquisition and/or generation.	ADC converter could be a 8/10/12/16 bits converter
Inversion	Inversion between the physical value and the logical value. This attribute is not visible butdone by I/O Hardware Abstraction to deliver expected values to users.	Physical HighState -> (signal=False) Physical LowState -> (signal=True)
Sampling rate	Time period required to get a signal value.	Sampling rate for a sampling windows (burst)
