That is indeed very annoying, Mentor is not the only one doing it.

Well, since all I have at home is the Altera free edition and in fact
it seems it's the only free Modelsim out for Linux right now (well,
Actel has a 45 day trial), I tried these out. Only example complains
about missing support:

Model Technology ModelSim ALTERA vlog 6.5b Compiler 2009.10 Oct  1 2009
-- Compiling module random_test
** Warning: ex2.sv(5): (vlog-2186) SystemVerilog testbench feature
(randomization, coverage or assertion) detected in the design.
These features are only supported in Questasim.

And trying to run it gives:

# vsim random_test      
# Loading sv_std.std
# Loading work.random_test
VSIM 3> run -all
# ** Fatal: ex2.sv(5): Unable to check out verification license for randomize() feature.
#    Time: 0 ps  Iteration: 0  Process: /random_test/#INITIAL#3 File: ex2.sv
# Fatal error in Module random_test at ex2.sv line 5
# 
# HDL call sequence:
# Stopped at ex2.sv 5 Module random_test

But all the others work. Not bad for a freebie...

Thanks everyone for your input. My question is relating to the cost of
a simulator that supports SystemVerilog Verfication, just how much
should I expect to spend for one license? If its too expensive I'll
have to stick with sytem testbenches.

If you have to ask you can't afford it...

Anyway you should check with Mentor, maybe they can give you a deal.
I've never used Questa myself, only Synopsys VCS.

To put a ball park on it, about the price of a relatively well-equiped
medium range car ;). If you get a great deal from Aldec / Cadence /
Mentor / Synopsys, maybe the price of a well equiped small car.

Why is it so expensive?

Not sure!  But I was completely blown away at how much discounts are
offered if you just ask for them... the car analogy really applies
here.  Even better would be a "used car"... i.e. you bargain as if you
are out to buy a used car.  Nevertheless, if you want a cheap tool to
learn Aldec Riviera Pro may be a good deal as well... ofcourse, here
you pay to debug Riviera for Aldec.
