LogiCORE IP Video Scaler v2.0 - Why does my pCore not have the parameters that I selected in the CORE Generator software?

Description

Why does my pCore not have the parameters that I selected in the CORE Generator software?

Why does the pCore always use the default core parameters, even though I changed it in the CORE Generator GUI before creating the pCore?

Solution

This is due to an issue where CORE Generator fails to update the MPD file and always generates with default values.

You can work around this problemby making changes to the core in XPS. Once you have added the scaler to your project, you can double-click on it andchange the parameters.

Three parameters that you might have questions about are:

1. C_TIMEOUT_ENFORCED This was a testing parameter thathas no affect on the core.
2. C_CHROMA_FORMAT 1 = 4:2:0, 2 = 4:2:2
3. C_DATA_SOURCE 0 = live (unchecked),1 = memory (checked)
