关于VMM中vmm_channel的问题？

anychao

哪位高人能够解释一下vmm_channel中的active slot到底是个什么东东？有点不明白啊！先拜谢了！！！

自己先顶一下！

用在producer/customer模型中，否则，只需要使用get或peek就可以了。
具体看源代码吧。

悉你

An important feature of channels is the active slot. The active slot keeps track of
the currently active transaction, allowing transactors to fill a channel without
retaining references to each transaction. The functions activate(), start(),
complete(), and remove() modify the active slot status so a consumer can
update the transaction status as it is processed. Typically, a channel consumer
should use the active slot and a producer should use put() followed by a
wait_for(ENDED) indication.

看看golden reference中和vmm_channel有关的内容就清楚了。

何必讲的那么抽象呢？其实是SV里面的mailbox的替代物，相较mailbox提供了更多的方法
