Virtual Sequencer

UVM

Virtual Sequence and Sequencers:

ByThe Art of Verification March 24, 2021April 23, 2021

Today I am going to talk about virtual sequences and the virtual sequencer. Common questions I hear from users include: why do we need a virtual sequence? How can we use it effectively? Most UVM testbenches are composed of reusable verification components unless we are working on block-level verification of a simple protocol like MIPI-CSI….
