PureDarwin is a pure hardware implementation of CoreWare : https://bitbucket.org/benallard/puredarwin
At the moment, it is not convertible, as lots of tests, as well as some tracebenchs in order to simulate it and observe the output in a vcd file (gtkwave). It is considered as being simulation capable.
