[swapnilm]

Can some one plz clarify the difference between UVM 1.1a ; UVM 1.1b and UVM 1.1c ?

Thanks in advance.

mainly for bug fixed for 1.1, should be transparent to users.

Thanks for your reply sir. Can you tell me any code built by using any version of UVM library can work fine with any other/lower versions of UVM library? Or does it give compilation error? Can you also give me some guidance about the commands to run a ready to go example? I am trying to compile an example from systemverilog.in (UVM example) using questasim 10.0b. But it is giving me lots n lots of compilation error. Please guide me.

Thanks in advance sir.

Please guide us into what kind of errors you are having. Better yet, why not ask on the systemverilog.in forum?

Dear Sir,

I already emailed systemverilog.in people but didnt receive any response yet. Besides I am not able to register in their forum as well, some kind of link issue, I guess. I compiled the UVM package but I m still getting lots of errors when I compile individual .sv files. Please find below the errors I am getting. Thanks a lot in advance.

Errors are below:-
