Thank for the reply and explanation about 'glitches'. The safe dff you linked to behaves differently to the built in dff, so is there a safe hardware implementation that behaves like the built-in dff? If not, why would they create a non-realistic dff? It doesn't seem necessary. It would actually be simpler to implement the proper dff.

Would the hack computer still work if the dff was changed so that the input is copied to the output at clockDown()?
