Parameter configuration list, set-up and procedures
17.3 Parameter configuration procedures
After the hardware connections for XDPL8218 configuration (see Figure 22 ) are done, please start the program
by clicking the shortcut “.dp Vision” on the desktop.
Note: During the program start-up, if the system shows there is a newer version of .dp Vision, please follow
the procedure and update accordingly. As the screenshots were taken based on .dp Vision version
2.0.9.1, it might look different for newer versions of .dp Vision.
A .dp Vision user manual is available by clicking [Help] >> [Help contents], to provide the detailed instructions
on how to use this GUI for parameter configuration. Alternatively, the following simple guide is also available
for quick and easy reference.
Open the XDPL8218 parameter configuration file (*.csv) from the default installation folder of the project add-
on at C:\Users\<Username>\Infineon Technologies AG\.dp vision\Parameters, as shown in
Figure 23 .

After opening the parameter csv file, a list of configurable parameters with default values based on the
reference board design will be shown (see the box on the left in
Figure 24 ). These default values can be
changed for another board design, by referring to the design guide from Section 2 to Section 15 and the fine-
tuning guide in Section 18 .
If a parameter value is changed and no limit violation is found, the changed value itself will turn blue, like the
example in
Figure 24 in which the R
cs
parameter in the hardware configuration section has been changed from
0.2 Ω to 0.18 Ω. Otherwise, if an error is detected (e.g. exceeded min./max. value), the parameter value which
caused the error will turn red and the message bar of .dp Vision (see the top right in
Figure 24 ) will show an
error message. If any error is not resolved, the user is not allowed to configure the IC with the changed value.

Note: For safety and proper system functioning, it is important to ensure the hardware configuration
section parameter values are compatible with the actual system hardware dimensioning.
