Oh, I forgot to mention how to run it for different vendor tools…

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

osvvmVariables = OsvvmVariables(
vhdlVersion = VHDLVersion.VHDL2008,
toolVendor = "Aldec"
toolName = "RivieraPRO"
toolVersion = "2024.10"
)

Hi Isaac,

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.

Can you please provide the output of

ghdl –version

Do you need this as strict “on” and “off” for tready or do you need e.g. random back-pressure on the bus?

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.

Usually, you can trust the synthesis tools. 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]

I don’t advertise simulations with Vivado xSim
* 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]

Your GTKwave is propably too old. You have 3.3.104, whereas GTKwave is now at 3.3.121.

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

Unfortunately, the made there own GHW reader as far as I know. So it could be failing as well.

GHW is a waveform format from GHDL specially made for…[Read more]
