This doesn't have any purpose, but serves as the base class for all UVM classes. The open structure, extensive automation, and standard transaction-level interfaces of UVM make it suitable for building functional verification environments ranging from simple block-level tests to the most complex coverage-driven testbenches. This post will provide a simple tutorial on this new verification methodology. The scoreboard is written by extending the UVM_SCOREBOARD.
