I don't have simulation models for the primitives, and I can't write them due to the lack of documentation. One of the downsides of working purely with the free / open-source toolchain, I guess. edit for clarification: The lack of simulation models is due to the free toolchain. The documentation is fully available, it's just so bad that you don't even know what some of the primitives are meant to do.
