Is there any support for callback in UVM or this is a completely user defined construct that testbench writers need to use? If UVM does support, an example would help a lot. Thanks,

In reply to verif_learner : The Story with the callbacks is a little bit more special. The pre_do, mid_do and post_do helps us to make modifications in RO sequences. It is highly recomended to deal with these callbacks when extending VIP sequence definitions.

In reply to verif_learner : Callbacks should never be used in a UVM environment as they introduce unneeded complexity and dependencies which limit re-use. Instead, TLM communication should be used to co-ordinate actions between components.

In reply to chr_sue : Sure. As far as the callbacks available in the framework, yes. Uuser defined callbacks, probably no. This is how I have interpreted …

Sure. That’s what I thought while going through a book on SV based verification.
