DDR I/O not in the Ultrazed design

sonictai
sonictai over 9 years ago

Hello,

I have followed the UltraZed EG Starter Kit Tutorial (for the 2016.4 Vivado version) to recreate the demo project, everything's OK, I am able to synthese and implement the design but when I open the implemented design there are no DDR and MIO I/O mapped to any pads!!

When I generate the block design there is no DDR port (in a Zynq 7000 project this DDR port appears), so the wrapper has no DDR interface, and then the design doesn't contains DDR interface!

Where are those DDR and MIO signals defined in the project? Not in any xdc file...is it normal that the DDR port isn't in the BD?

Thank you, Christophe

    Staring with MPSoC family, the PS dedicated pins such as DDR and MIO are no longer shown in the block design or in "implemented design" as these pins are not user defined in the top-level XDC file. You also won't see these ports in the top-level wrapper file. But rest asure, these pins are connected to the MPSoC external devices.

    Thank you for your fast response. However I was expecting to find them in the "package pins" part of the implemented design!

    You can view these pins in the Vivado IO Report.
