Getting Started with the XDPL8220 Reference Board Using .dp Vision Software
•
After opening the parameter csv file, a list of XDPL8220 configurable parameters will shown (see the box on
the left in
Figure 9
). These values can be then modified by users and will turn blue.
Attention:
.dpVision will check the plausibility of the parameters values which are input by the user.
If any value violates the limits, the value will turn red and an error message will appear in the
message bar as shown in
Figure 9
. The limits may also be dependent on other user inputs.
Users are not allowed to save, test or burn the configuration if there is error detected.

Changing Parameter Values in .dp Vision
There are 2 options available to configure the IC based on the parameter values in .dp Vision.
•
Burn Configuration
As the XDPL8220 chip on the 50W reference design PCB was already permanently burned with a first full set of
parameters in its one time programmable (OTP) memory space, any parameter value change using this option
is considered as parameter patching. The OTP memory space which is dedicated for patching or burning the
parameter value change has a memory size of 274 words.
Each time when the burn configuration function is executed, it will detect if there is parameter value difference
between the saved configuration file and the target XDPL8220. If there is difference detected, each burn
configuration will consume minimum 3 words depends on how many parameters need to be patched.
However, the process will be aborted if it consumes more memory space than what is remaining in the target
IC. As a result, the user will have to replace the target IC with a new XDPL8220 chip, in order to burn the
configuration.
Table 3
below shows the recommended procedures of using burn configuration function in .dp Vision to patch
the parameter into the OTP memory.
