Does OVM methodology supports Module based SV

Though the OVM is yet to be really seen outside, I will be surprised if it doesn't. For now you can refer to AVM, it has both. We at CVC recommend it based on the amount of investment one is ready to make. Module based thing gets you started faster, works with existing env etc. Infact we submitted a CDNLive India paper for this year based on a SPI block verification project. If you are in Bangalore we can help you better face-to-face if needed. Drop me an email ajeetha <> gmail.com if interested.

BTW - adopting a class based methodology your returns are lot higher and if done carefully it can co-exist peacefully with rest of your TB being module based. It may boil down to your tool support for constructs as well.

The joint development of OVM between Cadence and Mentor is focused on a common SystemVerilog Class Library and Class-based methodology. Cadence is committed to ensure that OVM will work with the rest of the Plan to Closure Methodology components, including SystemVerilog Module-Based URM as well as eRM. Since the Module-based approach does not require a class-library, there is not a dependency on the OVM classes, and Cadence is working to ensure that other dependencies like test-phases, debug messages, etc... will be consistent with OVM. Of course, the Module-based approach is also based on standard SystemVerilog, so any VIP developed using the Module-based approach will not only run on any IEEE1800 compliant simulator but also plug & play with both OVM and eRM VIP.

Our customers have told us that there are distinct implementation needs for engineers coming from a verilog, rtl programming background vs. an object-oriented, software programming background. This is why within the Plan-to-Closure methodology(IPCM) we provide different implementations yet they can still work together. These needs -- and our parallel approaches -- continue forward with OVM.

thanks mike...
                from this i understood that OVM does'nt supports Module based SV, am i rite?
                           if OVM contains libraries of module based SV then it supports?

Sorry....it was a typo.....instead of "does" it went as "doesn't"

"OVM does supports Module based SV!!!!"

Regrets,
