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... »
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 ... »
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... »
OSVVM 2015.03 is a minor release that updates only AlertLogPkg. All other packages remain unchanged. In AlertLogPkg, added AlertIfEqual, AlertIfNotEqual, and AlertIfDiff (file). Added ReadLogEnables to initialize LogEnables from a file. Added ReportNonZeroAlerts. Added PathTail to extract an instance name from MyEntity’PathName. Added ReportLogEnables and GetAlertLogName. See AlertLogPkg_Use... »
OSVVM 2015.01 is a major release that introduces AlertLogPkg. AlertLogPkg adds Alert and verbosity control procedures that are a powerful replacement for assert statements. All OSVVM packages have replaced asserts with alerts. VHDL assert statements have a limited form of an alert and verbosity control. Through a simulator, you can set an assertion level that will stop a simulation. Through a simu... »
I have just posted release 2014.07a. There are no new features in this release. It fixes memory leaks. The first (and biggest) issue is in the deallocate procedure in CoveragePkg for CovPType. The Name of each coverage bin is never deallocated when deallocate is called. If you called deallocate during your testing process, the space allocated for the bin names was never given back. Hence, if you a... »
