Virtual sequences and virtual sequencers are highlighted by building a small collection of examples that can be used in layered stimulus verification environments. The main contribution of this paper is a new layering component that performs the standard layering task while minimizing user programming without requiring exotic connectivity, extended components or the use of the factory.<\/p>\n<p>Using layered sequences can make your verification life easier, since sequences and sequencers are natively parallel and have arbitration and other communication process hooks already built-in.\u00a0 To learn more, download the kit.\u00a0 You will also find a presentation in the kit and how to use\u00a0 it with the <a href=\"http:\/\/www.ovmworld.org\/contributions-details.php?id=33&amp;keywords=A_Register_Package_for_OVM_-_ovm_register-2.0_Release\" target=\"_blank\" rel=\"noopener\">OVM 2.0 Register Package<\/a> mentioned in my <a href=\"https:\/\/blogs.mentor.com\/verificationhorizons\/blog\/2010\/05\/10\/ovm-20-register-package-released\/\" target=\"_blank\" rel=\"noopener\">last blog<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Download Now A new OVM Layering Package that provides a means to add layers of tests (sequences) without modifying the&#8230;<\/p>\n","protected":false},"author":71541,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"spanish_translation":"","french_translation":"","german_translation":"","italian_translation":"","polish_translation":"","japanese_translation":"","chinese_translation":"","footnotes":""},"categories":[1],"tags":[442,573,623,682],"industry":[],"product":[],"coauthors":[],"class_list":["post-1146","post","type-post","status-publish","format-standard","hentry","category-news","tag-dvcon","tag-layered-sequences","tag-ovm","tag-register-package"],"_links":{"self":[{"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/posts\/1146","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/users\/71541"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/comments?post=1146"}],"version-history":[{"count":1,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/posts\/1146\/revisions"}],"predecessor-version":[{"id":14659,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/posts\/1146\/revisions\/14659"}],"wp:attachment":[{"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/media?parent=1146"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/categories?post=1146"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/tags?post=1146"},{"taxonomy":"industry","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/industry?post=1146"},{"taxonomy":"product","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/product?post=1146"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/blogs.sw.siemens.com\/verificationhorizons\/wp-json\/wp\/v2\/coauthors?post=1146"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
