Is it possible to IS_SOFT nested pblock under a DFX pblock?

Jump to solution

Hi,

When I attempt to apply IS_SOFT property to a pblock wholly inside a DFX pblock, I am getting the following warning:

WARNING: [Constraints 18-5661] Only False is supported for IS_SOFT property on Pblock XXX due to its Hierarchical Design flow requirement.

 

But the pblock in question is not part of a Hierarchical Design flow (only its parent is). Is it currently not possible in vivado to have soft pblock nested within a parent DFX pblock?

Thanks,

Terry

Hi @terry_chen_3red,

Child pblock under a reconfigurable pblock inherits IS_SOFT=false. This cannot be changed.
