Advances in OSVVM’s Verification Data Structures (US)
June 23 @ 11:00 AM - 12:00 PM
OSVVM has grown tremendously over the last couple of years. This period saw simulator independent scripting, test reporting, model independent transactions, virtual transaction interfaces, and additional verification components, each added and incrementally improved. We have talked about these previously in this webinar series.
This webinar focuses on advances in OSVVM data structures. OSVVM’s Functional Coverage, Scoreboard, FIFO, and Memory data structures are now all based on singletons – in a similar fashion to what is done in AlertLogPkg.
Using singletons significantly simplifies each data structure’s USER API – the call interface. Specifically, users no longer need to use shared variables, protected types, and their complications. We will discuss the new APIs, their advantages, and some of the improvements OSVVM was able to make by using these.
Don’t worry though, we still support the older protected type data structures.
One of the advantages of the updated data structures was discussed in Part 3 of this webinar series – reports for Functional Coverage and Scoreboards are automatically generated simply by running the tests with OSVVM scripting and calling “EndOfTestReports” rather than “ReportAlerts” at the end of the test.
- Are simple to use and work like built-in language features.
- Maximize reuse and reduce project schedule.
- Improve readability and reviewability by the whole team including software and system engineers.
- Facilitate debug with HTML based test suite and test case reporting.
- Support continuous integration (CI/CD) with JUnit XML test suite reporting.
- Provide buzz word features including Constrained Random, Functional Coverage, Scoreboards, FIFOs, Memory Models, error logging and reporting, and message filtering.
- Rival the verification capabilities of SystemVerilog + UVM.
