What is ASAP2 file?
The ASAM MCD-2 MC standard, also known as ASAP2, is a data definition standard proposed by the Association for Standardization of Automation and Measuring Systems (ASAM). ASAP2 is a non-object-oriented description of the data used for measurement, calibration, and diagnostic systems.
How do I view A2L files?
The A2L Viewer interface looks as shown below: LabVIEW examples for reading A2L Files can be found in LabVIEW under Help >> Find Examples >> Toolkits and Modules >> ECU Measurement and Calibration >> Advanced.
How do I make an elf A2L file?
Using the Exporter
- To use the A2L exporter, select File -> Export from within Arctic Studio, and then choose the option Other -> A2L file.
- After you click Next, you’ll be presented with the options for the A2L Exporter.
- ELF file should be the binary file of your RTE.
- Output A2L file should be your desired output file.
What is XCP in autosar?
AUTOSAR Basic Software module XCP. XCP is a protocol description (ASAM standard) between a master (tool) and a slave. (device), which provides the following basic features: – Synchronous data acquisition (measurement) – Synchronous data stimulation (for rapid prototyping)
What does A2L file contains?
An ASAP2 description file (also called A2L) contains all information about the relevant data objects in the ECU, such as parameters, maps, real and virtual measured variables, structures and variant dependencies.
What is A2L and HEX file?
Each ECU contains A2L file and Hex file which includes information about the parameters of the ECU. ECU contains two types of Hex file, some of the ECU contains Intel Hex and some ECU contains Motorola S19 format. Input for calibration tool is Hex file and A2L file for launching communication with ECU.
What is A2L file in autosar?
An A2L file contains information on the relevant measurement objects in the ECU. Along with the description of parameters for commu- nication between the XCP Master (e.g. analysis tool) and the XCP Slave (ECU), an A2L file also contains a hierarchi- cally structured representation of the measurement ob- jects.

Can vs XCP?
XCP is a successor to CAN Calibration Protocol (CCP) that was developed back in the mid-1990s. At that time, CAN was the dominant networking system in the automobile industry. Over time, other bus systems such as LIN, MOST and FlexRay emerged and made it necessary to extend the protocol to other transport media.
What is XCP used for?
The XCP protocol is commonly used in the automotive industry to measure and calibrate electronic control units (ECUs). Specifically, engineers use it to read measurement data and write parameters to ECUs during development, testing, and in-vehicle calibration.
What is CCP and XCP?
The XCP protocol builds upon the standard CCP command structure by adding additional optional commands to enhance previously time consuming operations for calibration (download commands) and flashing (programming commands).
What is the use of A2L file?
Contents of the ASAP2 database An ASAP2 description file (also called A2L) contains all information about the relevant data objects in the ECU, such as parameters, maps, real and virtual measured variables, structures and variant dependencies.
How to create a description file in ASAP2?
An ASAP2 description file (A2L) is a prerequisite for using CCP and XCP as a measurement and calibration protocol. The ASAP2 Tool-Set is used to create and check such ECU description files. It consists of the ASAP2 Studio and six command line programs that you configure via initialization files.
What do you need to know about ASAP2?
ASAP2 information such as data type, conversion rules, min-max conditions, structures, arrays, etc. are defined via these comments. The ASAP2 Updater reads an A2L source file, matches the information with entries from a linker MAP file, generates missing objects if needed, and creates a new A2L file.
How is the ASAP2 tool set used in ECU?
The ASAP2 Tool-Set is used to create and check such ECU description files. It consists of the ASAP2 Studio and six command line programs that you configure via initialization files.
How to compare two A2L files in ASAP2?
With ASAP2 Comparer you can quickly and easily compare two A2L files and generate documentation of the comparison result. Not every A2L file meets the criteria of the standard. To ensure a high level of process reliability throughout the entire tool chain, an A2L file is checked for compliance with the standard and deviations are highlighted.
