In reply to tfitz:
Please see the UVM Cookbook.
Note that we don not recommend the use of virtual sequence**r**s, as they are not strictly necessary and can limit reuse by enforcing additional hierarchy in your environment. The link above shows how you can use virtual sequences without using a virtual sequencer. However, if you insist on using a virtual sequencer, there is a link at the bottom of the page that discusses them.
Thanks tfitz,
I think this is depending on the project style. if I need to handle of 300 sequencers or more , once I will make a virtual sequences library then I can use handy keyword (p_sequence) and connect to sequences. it is more handy and cost effective. What do you think ?
If you dont mind, Would you please introduce about what you recommend like it?
