UCR in synthesis

[Syed-mudabbir-ahsan]

Hi team,

We are facing some unclocked registers as shown below; looks like clock enable of write buffers wrbuf_dataff and wrbuf_adrff is LOW since AXI control signals are low as AXI is unused, does this impact any other loads of Caliptra RTL? In synthesis we have ignored unloaded issue since axi path is unused but just confirm this UCR issue doesnt impact any useful loads.,
