Hi Senthil,
This is now fixed on the dev branch of OsvvmLibraries on GitHub. You can get the dev branch by doing:

git clone --recursive --branch dev https://github.com/osvvm/OsvvmLibraries

Best Regards,
Jim

It is Simon doing the heavy lifting.

Thanks Jim and Simon! This clears things up.

Hi Eamon,
I have asked Simon to post a response to this. Unfortunately the website is having some issues with Simon being able to post a response to it. Hopefully it will be resolved shortly.

Many apologies. We usually get these type of things answered within a day or two of the post.

Best Regards,
Jim

Hi Senthil
OutputHomeDirectory is not the correct variable to be setting.
Please use OutputBaseDirectory.

I have tested it with settings as follows. In both of these the results are in the $CurrentSimulationDirectory.
variable OutputBaseDirectory “”
variable OutputBaseDirectory “osvvm”

I have not tested it with other than these…[Read more]

Hi Jim,

Following up on my earlier email regarding setting a new location to write OSVVM outputs other than the current Simulation directory. My setup now has OSVVM_SETTINGS_DIR env variable pointing to OsvvmSettingsLocal.tcl, I am
able to read in the user settings specified in OsvvmSettingsLocal.tcl.

These variables are active,
variable…[Read more]

Hi Jon,
I recommend getting all of OsvvmLibraries. Then from the Script_user_guide.pdf, to start XSIM, do the following:

1.3.9 Xilinx XSIM
Using OSVVM in Xilinx XSIM is under development. So far, Xilinx seems to be able to
compile OSVVM utility library, however, we have not had any of our internal test cases
pass.
To run OSVVM scripts in XSIM,…

Hello,

I’m working on some video processing HDL. For debugging operations like smoothing, spectrogram, colorspace conversion, etc I get limited utility out of peaking an output AXI stream and using that on a scoreboard. I’ve seen SDL2 + Verilator used online to write AXI stream contents to a framebuffer. Is something like this possible in the…[Read more]

Hi Senthil,
Settings have been changed through time. What I say here pertains to the current release, 2025.06a. Typically I try to keep changes backward compatible.

You will find how to for OSVVM’s tcl and vhdl settings documented in OsvvmSettings_user_guide.pdf in OsvvmLibraries/Documentation. With respect to finding the settings files, it…[Read more]
