Update to the OVM Register Package

Comments(3)Filed under: Functional Verification, OVM, OVMWorld, IES, Register Package, IP-XACT, verification, Incisive, uvm

OVM users have something new to give thanks for this holiday season -- an update to the OVM Register Package (new link!!). This package is used by novice and advanced users and embodies years of experience gathered through hundreds of SystemVerilog projects.

The Cadence genIES team has been remiss since the demise of the OVM World, which left the OVM community to use OVM_RGM 2.5.  We did try to post to UVM World, but that is really dedicated to the UVM.  Therefore, we will be picking up the contribution thread and maintaining the Cadence contributions to the OVM here.  By far the most popular is the register package so we are posting the latest version 2.7.1 here.  We've included the release notes from 2.6, 2.7, and 2.7.1 to bring you all up to date.  Of course, the complete release note history is in the tarball.

Hi, would you please check your download link and file again, because I am getting errors while trying to extract the ovm_reg_2.7.1.tar.gz. It seems the archive is damaged. Thanks.

Thanks for noticing the problem with the file.  We had a problem uploading that left the zip corrupt.  We tried it from both Chrome and IE and it works.
