In reply to MayurKubavat:
The value returned by uvm_re_match is an error code from regexec. So 0 is in fact successful.

I have asked the same question. I am thinking it would be great if UVM can add one line of explanation on uvm_re_match(), instead of users have to look into the code or C code to figure it out. IMHO.
