【问题】关于UVM的复用

chainingruijie1

Sequence Item Overrides:
In principle, the same factory override mechanism could be used for sequence_items. However, it would require a driver
to be written with prior knowledge of the derived type, so that it could cast a received sequence_item to the right type.
Therefore, from a practical point of view, sequence_items are unlikely to be overriden.
根据这么说可能item的override不是太灵，不知道我理解的对不对

BFM调用item提供的function或者task来完成数据的pack或者unpack，这样，只要接口不变，数据结构怎么变，都可以只override item提供的pack/unpack。

No you need not change any bit of code,use instance_override_by_* methods from the factory ovrride the instance of sequence_item in your sequence

First you should review the UVM guide and OVM guide, Be sure you master the basic verification mthodology!
