In a constrained random approach, different items can be selected more frequently by using randomization weights. Items with a higher randomization weight are selected more frequently. In Intelligent Coverage, the same effect can be achieved by using coverage goals. A coverage goal specifies how many times a value must land in a bin before the bin is considered covered. Each bin within the coverag... »
When writing functional coverage it is important to be able to capture all the details of a model. With item (aka point) coverage, both VHDL and SystemVerilog do a good job. However with cross coverage, if the model requires more than a simple Cartesian product, SystemVerilog falls short. OSVVM, on the other hand, offers a rich cross coverage capability.

Recently Matthias Alles of Creonic shared his OSVVM usage story. I would like to invite you to share how you are using OSVVM. Send a copy of your proposed article to myself (jim at SynthWorks) or Jerry (Jerry at Aldec). From there we can get you setup to post it to the blog. »
OSVVM release 2013.04 is now available at OSVVM Downloads. »
Currently the IEEE P1076 Working group is reviewing a draft of the proposed IP Encryption (P1735) and accessing how it maps into the pragmas created in VHDL-2008. If you are developing and/or selling VHDL IP that you want to encrypt, you should be participating in this. More details at: https://www.eda.org/twiki/bin/view.cgi/P1076/ To participate, contact Jim at SynthWorks.com »
