User Options: Limited EMU RAM Tab
To go to this tab, click the User Options
button and select the Limited EMU RAM
tab.
For detailed information on limited emulation RAM functionality, see the PDF document Serial (X)ETK Calibration Concepts Limited Emulation RAM, which you can find in the Manuals folder of your INCA installation.
You can make the following settings:
Defines the calibration method to be used for devices with limited emulation memory (EMU RAM).
Dynamic emulation
The emulation ranges are set dynamically when a variable is calibrated.
If you use dynamic emulation, you must enable the checksum calculation for the working and reference page (option Verify Checksum on the Hardware tab)
Experiment preparation
The emulation ranges must be defined explicitly.
Changes in this setting only become valid after restarting INCA.
Note
The default operation mode is with experiment preparation. If you change the operation mode towards dynamic emulation and use an ETK type which does not support this type of operation, INCA automatically uses the default mode with experiment preparation and displays a corresponding message.
If you want to work with dynamic emulation, you must explicitly set this user option to Dynamic emulation.
Defines when calibration is allowed in the dynamic emulation operation mode.
Force equal RPs
Calibration with different reference pages on ECU and computer is not possible.
Allow calibrations with different RPs
Calibration with different reference pages is possible if all calibrations of the used ECU project can be emulated (full ECU project emulation).
Changes in this setting only become valid after restarting INCA.
Some ECU projects require that parts of emulation areas not described in the A2L file as MEMORY_SEGMENT be initialized with fill bytes.
With this option you can specify whether these fill bytes are to be written to the control unit memory, or not, when you download the working page for serial ETKs that use the calibration method Limited Emulation RAM or Dynamic Emulation RAM.
Yes
When downloading the working page to the ECU, for parts of emulation areas that are not described as a MEMORY_SEGMENT with the memory type FLASH in the A2L file, fill bytes are written to the ECU's memory (default setting).
No
When downloading the working page to the ECU, only the parts of the emulation areas that are described in the A2L file as a MEMORY_SEGMENT with the memory type FLASH are downloaded. Emulation areas with other memory types are not downloaded.
Note
If a MEMORY_SEGMENT with the memory type FLASH is defined in the A2L file, but the associated Hex file does not contain corresponding data, fill bytes are written to the Hex file when importing into INCA. These fill bytes are always downloaded as well. The option can only be used to suppress downloading of fill bytes for emulation areas which are not defined in the A2L file.
In experiment full emulation mode, INCA automatically configures the emulation RAM to emulate all calibrations in the experiment at once.
Note
Experiment full emulation is only supported with the operation mode Dynamic Emulation and if the CALIBRATION_METHOD ReconfigurableSizeMoveableEmuRAM is defined in the A2L file.
Yes
INCA tries to emulate all calibrations in the experiment at once. If this is not possible, only the differences between Working Page and Reference Page are emulated.
This setting is useful if you are working with an INCA experiment where all needed calibrations are already configured: in this case you will get the best emulation RAM configuration after opening the experiment.
No
INCA tries to emulate only those calibration variables with differences between Working Page and Reference Page.
This option setting is useful whenever you would like to add further calibrations after opening the experiment; otherwise, the system might run out of free emulation RAM segments, because all calibrations in the experiment are already emulated, including those that are not necessarily needed for your task.
