Can't generate DeviceResources file for Versal #968

Open Quadrollopo opened 3 months ago

Quadrollopo commented 3 months ago

I tried to generate the DeviceResources file for Versal with rapidwright DeviceResourcesExample xcvc1902 but the output will always end with a NullPointerException: 

==                     Device Resources Dump: xcvc1902                      ==

I also tried different Versal devices but it will always end up like the previous output.
For other non-Versal devices the command would work fine.

Thank you for reporting this issue. I have created a workaround so that a Device Resources file can successfully be generated, you'll need this PR: https://github.com/Xilinx/RapidWright/pull/969.

A larger, more permanent fix will come a bit later.
