Just because your design is complex does not mean your testbench needs to be. In OSVVM we have found that with proper abstractions we can create simple, readable, and powerful testbenches. In OSVVM 2016.11 we released the transaction based modeling approach we have been using for the past 20 years in our verification practice and classes. Looking at its block diagram, you will notice that its arch... »
I am getting ready for the next session of Advanced Testbenches and Verification in UK and am looking forward to meeting another group of students. Ready to improve your VHDL verification methodology? Come join me, Jim Lewis, the OSVVM chief architect, for the class, Advanced VHDL Testbenches and Verification, and learn OSVVM step by step. If you want to learn what is in OSVVM, you can read the ma... »
2016.11a is a minor release. The only file that changed is VendorCovApiPkg_Aldec.vhd. There was a bug in one of the attributes that has been fixed and verified. VendorCovApiPKg simplifies the connection between OSVVM functional coverage a vendor’s internal functional coverage database. The operation of the API is simple. Within OSVVM, all calls to create a functional coverage model (AddBins ... »
Webinar From OSVVM to UCIS Database. Thursday December 15, 2016 When a simulator records functional coverage internally, it gains the ability to correlate the functional coverage with its verification planning tools and share that information with safety critical tools. The 2016.11 release of Open Source VHDL Verification Methodology (OSVVM) adds an API to record OSVVM Functional Coverage directly... »

OSVVM 2016.01 Tested On Some may think that OSVVM only works on a particular simulator. Not so. I test OSVVM on the latest release of Aldec ActiveHDL, Aldec RivieraPro, Mentor QuestaSim, and GHDL that I have installed. 2016.01 was tested and passes all regressions on: Aldec ActiveHDL 10.2 Aldec RivieraPro 2015.02 Mentor QuestaSim 10.4d GHDL 0.33 Beyond OSVVM 2016.01 Any minor bugs that are found w... »
OSVVM on GitHub OSVVM is now on GitHub. You can find releases there. I will be putting bug patches there first before formally releasing them on OSVVM.org. Long term I also plan on putting tool specific branches as needed (such as for Cadence). https://github.com/JimLewis/OSVVM OSVVM Training in Germany In conjunction with PLC2, we will be offering OSVVM training in Germany. See the matrix below f... »
2016.01 Fixed a bug in AlertLogPkg that kept more than 32 AlertLogIDs from being used. Updated CoveragePkg, MemoryPkg, and TextUtilPkg for GHDL (function purity and indexing objects of type line) 2015.06 (released previously, but not announced) Added MemoryPkg to easily implement sparse data structures used in memory models. In AlertLogPkg, added AffirmIf, added PASSED log level. In CoveragePkg, i... »
Webinar OSVVM for VHDL Testbenches. Thursday June 25, 2015 Open Source VHDL Verification Methodology (OSVVM) is a comprehensive, advanced VHDL verification methodology. Like UVM, OSVVM is a library of free, open-source code (packages). OSVVM uses this library to implement functional coverage, constrained random tests, and Intelligent Coverage random tests with a conciseness, simplicity and capabil... »
