opt_design error (Implementation Failed)

After writing my program and verifying my outputs in behavioral simulation, I'm getting the following error:

"[opt 31-2] SRL16E m3/inst/ila_core_inst/shifted_data_in_reg[7][177]_srl8 is missing a connection on D pin"

I've verified my VIO and ILA mapping even which are correct. 

Any suggestions would be appreciated.

Re: opt_design error (Implementation Failed)

Hi, h20181230210@hyderabad.bits-pilani.ac.in ,

Which version of Vivado are you using? Could you try the latest version?

Could you try to run opt_design with single option to check which one causes the issue?

Ex: 

opt_design -sweep

opt_design -retarget

opt_design -propconst
