AVL Scoreboards

Scoreboards provide an essential part of verification environments, but error prone and often lack basic functionality.

AVL provides 2 simple scoreboard implementations that are simple to extend and catch the most common errors.

1. Ensuring a minimum number of items are compared. This avoids the common use-case where a scoreboard has been forgotten to be connected to the DUT.

2. Ensuring that all items have been compared. This avoids the common use-case where items are left in the scoreboard un-compared at the end of the simulation.

The AVL scoreboards are connected using a pair of lists (avl.List).

When both ports contain items, the scoreboard will pop from the list using the List.blocking_pop method and call a bi-directional Object.compare.
