I have a customer ip core generated by synplify, input is edf file; in this ip, containing an encrypted xilinx ip core multadd. I have to set black box for this encrypted ip, and add a wrapper.
I use this customer ip in BD design, and add this multadd xci file in project.
but Opt tool will complain multadd black box. So for this kind of usage, how to let Implementation tool to use multadd xci file? Thanks!
The failure log:
