Hi Snehasish, I forgot about that error. I actually made an issue about it on their repo: https://github.com/SynchronousLabs/rfnoc-SynchronousLabs/issues/2. Unless they provide an EDIF or their source code, you can only use their code for simulation. Certainly a disappointing oversight on their part.
