how to report tool(vcs/ncsim..)/assertion related errors in UVM

Hi,

we see different kind of failures when we run simulations, like assertion error, uvm_error. 

How do we report outside UVM errors in report phase to give the TEST STATUS?

I am getting some psl/ovl/sva assertion  errors, but, UVM part is not reporting any error. 

how do I report test STATUS??

Thanks,

Satya
