Hi,
There is quite a bit available in the web, do a google search. I've co-authored 2 books on SystemVerilog applications, see www.systemverilog.us Given systemVerilog is massive in its size, you can do a better job of using it if you follow a good methodology and that's what our recent book on VMM adoption talks about.
Our SVA Handbook is also available for preview in books.google.com
