CI failures seem to be completely unrelated. (One is probably a bug in Verilator caching?) |

Thanks for the PR. I think there might be a more general solution for 0-bit wires which is why I would rather not merge this yet. |

As discussed in #35,
chiseltestdoes not currently support zero-width data/ports.This PR provides a solution (well, maybe a workaround) specific to
DecoupledandValidinterfaces. Decoupled interfaces with zero-width data can also be used
as a control/synchronization handshake where no data exchange is required.
Here we take an explicit approach: the designer knows the
width of data at instantiation and can accordingly utilize appropriate
Option[Data]values.
