uvm中sequence和sequencer注册咨询！！

s19812500

在uvm中，一般来说，对于sequenc和sequencer有两种注册方法：

1，sequence：·uvm_object_utils(sequence)
     sequencer：·uvm_component_utils(sequencer)

2，sequence：·uvm_sequence_utils（sequence）
     sequencer：·uvm_sequencer_utils（sequencer，sequence）

这两种方法有什么区别，各有什么优点，请高手指点呢？

前者应该还缺少一个sequence和sequencer的对应处理，记得是一个带后缀lib的宏。曾经在国外论坛看到说不建议用第二种方式注册序列。

    一般来看都是第一种注册，只是在别人的一个平台中看到了这种方式，又没有找到相关的资料，就问问高手了。谢谢！

First Create a sequencer and register with sequencer utils `uvm_sequencer_utils(sequencer_name)

and now create a sequence and register that sequence with the factory and as well as the sequencer Lib
`uvm_sequence_utils(sequence_name,sequencer_name)

every sequencer by default wil have its own sequence library
when in the function new(); inside your sequencer use the macro......`uvm_update_sequence_lib_and_item
all the sequences registered with this sequencer will be updated automatically and the sequencer will know it and update internally in his sequence library
