NativeLink_simulation.rpt Error Report. How Can I correct the Error?

Hello all,

I launched a testbench simulation using NativeLink and I got these errors reported in the ...nativelink_simulation.rpt file.

Error: (vsim-SDF-3250) MBHPCP_State_Controller_with_MAX3000A_for_test_vhd.sdo(0): Failed to find INSTANCE '/system'.

Error: (vsim-SDF-3894) : Errors occured in reading and resolving instances from compiled SDF file(s).

Please what does it mean and how can I resolve it?

Thanks in advance.
