target=\"_blank\" rel=\"noopener\"><strong>UVM Layering 1.0 Package<\/strong><\/a>, like the OVM one, provides the means to add layers of tests (sequences) without modifying the underlying testbench and without extending components or using the factory to override implementations.\u00a0 The package also provides the DVCon paper and presentation that describes it in more detail in case you did not attend DVCon.<\/p>\n<p>Users have found layered sequences can make verification life easier as sequences and sequencers are natively parallel and have arbitration and other communication process hooks already built-in.\u00a0 The package is a companion to the <a href=\"http:\/\/www.ovmworld.org\/contributions-details.php?id=81&amp;keywords=A_Register_Package_for_UVM_-_uvm_register-2.0_Release\"
