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”
compile_vhdl -library osvvm $OSVVM_HOME/Common/src/AddressBusResponderTransactionPkg.vhd
