Remy replied to the topic Vivado : Error with AXI Data width in the forum OSVVM 1 week, 3 days ago
Hi Jim,
I updated the AXI FULL OSVVM testbench available here.
architecture TestHarness of TbAxi4 is
constant AXI_ADDR_WIDTH : integer := 16 ;
constant AXI_DATA_WIDTH : integer := 256 ;
constant AXI_STRB_WIDTH : integer := AXI_DATA_WIDTH/8 ;
I modified the width of AXI DATA and AXI ADDR, and adapted the test cases to include the new…[Read more]

Hi Remy,
Can you share exactly what you updated? Is it a particular OSVVM testbench or one of your own.The test cases that do bursts as words will not work as they likely have dependencies on a specific size interface. The test cases that do bursts as bytes are expected to work though.
Best Regards,

Hello,
I am using OSVVM 2025 with Vivado 2025.1.1.
I started from the AXI example.
When I change the values of AXI_ADDR_WIDTH to 16 and AXI_DATA_WIDTH to 256, the signals sWData, sWValid, and sWReady become undefined.
Is this bug dependent on Vivado or AXI drivers? -

Hi Jim,
Thanks for that. I had noticed from other questions that this may have been the issue.
Strangely, I am actually using Questa 2024.3 with OSVVM 2025.06a and I get the issue. As suggested I placed “SetVHDLVersion 2008” in my sim script and everything worked just fine.Cheers,
Nigel

Hi Hassan,
What version of OSVVM are you using? The current version is 2025.06a.
What simulator and version are you using?> 1. When only the testbench code was compiled. Why did it say “failed”?
Perhaps you can share the log files with me so I can look at it. Ultimately I need a reproducer test case of this.
Also tryputs $::…[Read more] -

Here are the steps:
First compile everything.
build ../OsvvmLibraries/OsvvmLibraries.pro
…Later just compile the DUT, lets say that it is the AXI4.
build ../OsvvmLibraries/Axi4/Axi4/build.proNow compile the testbench for this DUT:
build ../OsvvmLibraries/Axi4/Axi4/testbench/build.proNow run single test:

Hi Nigel,
In the OSVVM 2024.09 and 2025.02 releases, the 2019 compile switch was turned on if the Questa release is greater than 2024.2. With the OSVVM 2025.04a release and beyond the 2019 switch it is turned back off again. So I recommend getting the newest release of OSVVM (2025.06a) and this problem is resolved.In Questa, your issue is…[Read more]
