I did send the email. I had system copy me in so I know it was sent. I wanted to share the HDL I’ve completed thus far. I suppose this isn’t the place to do that. Any suggestions?

What did the e-mail start with? I don't know if I got it or not. I got a couple of e-mails that appear to be posts that were later deleted, but maybe they were actually e-mails you sent via the system.

But to get the ball rolling: I was wanting to use a Mux4Way16 and wire it up using sel[0]=zx and sel[1]=nx but the interface doesn't seem to allow that, or maybe I'm just not understanding the HDL syntax? Or maybe it would be better to wire together more Mux16s?

What is the error message you are getting when you try to use the Mux4Way16?

Using that part is perfectly reasonable -- as is using separate Mux16s and piping the output from one to the other.
