Jim Lewis replied to the topic Using VCs without the built-in Scripts – but instead VUnit in the forum OSVVM 3 weeks, 6 days ago
Hi Isaac,
From time to time, the OSVVM compile scripts are updated. It is hard to maintain more than one approach. The reason we developed the OSVVM scripts is to provide a better reporting mechanism. In addition the the ordinary JUnit reports, OSVVM does a more comprehensive Build summary. We also do test case summaries, functional…[Read more] -

Hi everyone,
currently I’m setting up a verification environment with an AXI (Full) verification component (VC) at work. I’ve ran several demos in the past using the built-in Scripts, however, now I would like to compile everything from scratch to target our verification environment (Questa + VUnit). My question is: is there a recommended way to…[Read more]

Jim Lewis replied to the topic Issues with GHDL when compiling OSVVM packages in the forum OSVVM 1 month ago
Are you running a current version of GHDL? Our github actions run with GHDL every day. See: https://github.com/OSVVM/OsvvmLibraries/actions
Did you use the directions in OsvvmLibraries/Documentation/Scripts_user_guide.pdf?
Here they are:
GHDL in Windows

I first compiled the required dependencies and GHDL compiled them well. but when I compiled the AlertLogPkg.vhd, it didn’t and showed error like, ^

The problem is, with Ubuntu 24.04, I think we can install the latest GHDL with snap store, but I have pop!_os 22.04 which is like Ubuntu 22.04. Here I have to install GHDL from github. I installed 5.0.1 GHDL. But I have all sorts of problems (with dependencies as I am doing it manually) where I couldn’t initialise and create the first work object…[Read more]

You need XSIM if you are using Xilinx’s encrypted IP. However XSIM is very slow.
GHDL and nvc both support OSVVM well – however they need a third party waveform viewer such as SURFER.
OSVVM is updated several times each year. Even if a simulator includes an OSVVM release, it may be out of date.
OSVVM is fast to compile the project.…[Read more]

I heard that there is no built-in support for osvvm with GHDL, but there is contrastingly, a built-in support for OSVVM in XSim. Also I tried with the help of ChatGPT to try and simulate a simple adder.vhd using OSVVM. I couldn’t do it. the compilation is not proper as it might miss some dependencies, and it’s all manual and I find it very…[Read more]

Ariel replied to the topic Waveforms not generated correctly (GHDL) in the forum OSVVM 1 month, 1 week ago
Hi. I think you might have an old GHDL version.
`
$ rlwrap -c tclsh
$ source ../OsvvmLibraries/Scripts/StartUp.tcl
OSVVM Script Version: 2025.02
Simulator Version: GHDL-5.0.0-dev

Christon Fredrick replied to the topic Waveforms not generated correctly (GHDL) in the forum OSVVM 1 month, 1 week ago
Hi, I see that you have some successful simulations with GHDL. may I ask which version of GHDL is compatible with OSVVM 2025.2? I am having the build error when I used GHDL 3.0.0 version. the normal libraries are being built with “rlwrap tclsh”, but when i want to build my adder_tb, it is not being build, and has errors. what am I doing wrong? I…[Read more]

You need OSVVM 2025.02 (or newer) and XSIM 2024.2

I have migrated to 2025.4, and things are working well for me so far. Thanks Jim!
