Hi Swapnil,
Can you let me know what your UVM_HOME is set it?
It must be set to <directory_in_which_uvm_lib_is_stored>/uvm1.0p1
As per the instructions in the Testbench.in, it is asking you to set to …/uvm1.0p1/src and that might be causing the unwanted errors in your case.
Correct the UVM_HOME setting and try again.
Thanks,
Rajkumar.
