You get a data model where you can access fields and aggregated files as well as status properties.

The instantiation of the OsvvmProFileProcessor takes an optional argument of type OsvvmVariables

osvvmVariables = OsvvmVariables(
vhdlVersion = VHDLVersion.VHDL2008,
toolVendor = "Aldec"
toolName = "RivieraPRO"

a few weeks ago, I release pyEDAA.OSVVM as part of the bigger EDA² Python package family. It provides a OSVVM *.pro file processor as well as data models and parsers for OSVVM’s YAML (and XML) file formats.

I think for the latter we need @JimL answer. For the former, you can setup a coverage model, which acts as a distribution function. This CovModel can be handed over to the receiver to randomly accept data or delay reception.

If you really mistrust them, you should skip post-synthesis and post-placement simulation and go to post-routing simulation. Post-synthesis is just after synthesis without optimization, placement and routing. So you would miss critical parts in the transformation from VHDL to bitstream.

Please keep in…[Read more]

* very low speed (>10x) compare to commercial simulators or open-source simulators
* creates masses of output data (multiple GB where others write just a few MB)
* explicit VHDL features like range checks need to be activated by the user (if not, xSim doesn’t produce correct simulation results…[Read more]

You have 3.3.104, whereas GTKwave is now at 3.3.121.

What platform do you use?
Linux, macOS, Windows, MSYS2, …?

has anyone experience in using OSVVM in safety-critical environments like avionics according or close to DO-254 and DAL-A or DAL-B?

We would like to use OSVVM in a customer project to avoid reinventing the wheel, being more productive and getting ready to use reports. We have now a question how mature is OSVVM and can it…[Read more]
