the GHDL version was 5.0.1, but good news, the OSVVM packages compiled with NVC. And also the basic VHDL code ran and the random function is really powerful when implemented. Really appreciate the work in OSVVM!

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, ^
osvvm/AlertLogPkg.vhd:5356:43:error: no overloaded function found matching “to_string”
“= Expected : ” &…[Read more]

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]

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]

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]

I’m a beginner. I am trying to add the library in the Vivado Project, but in TCL scritps, I am getting this error for the following commands.

create_lib -simlib osvvm $OSVVM_HOME/compiled_simlib/osvvm
invalid command name “create_lib”
