Hi Dreku,

By using -L switch in vsim, the error of vmm_str_match is removed but the design is not loading during simulation
.

What is the error message?
Have you tried one of the examples from Mentor's Verification Academy?
http://www.verificationacademy.com/ I suspect they have a forum there that might have users with a little more experience with Questa and the VMM (+ UVM + OVM) libraries
If you can setup a small example SystemVerilog example, I can try simulating it with Modelsim-SE, I think I have all the Questa stuff supported, if not, I can download it from Mentor.
Cheers,
Dave
