Hi Andy,
Sorry for the delay in replying. I did look at personalities a little
while ago and didn't really get my head around it at the time. I have to
admit I didn't put much time into it.
Looking at the code this looks suspect:
out(i) = (bargraph) ? (in > i) : (in == i);
Shouldn't it be:
out[i] = (bargraph) ? (in > i) : (in == i);
I have no idea why the compiler would have let that through.
Do you want to commit your version? It is better than mine. You might as
well put your name on it as there isn't much left of what I wrote ;-)

This is the inverse of the mux components. It takes an integer value and

I don't know how much comp has changed since the date on that comp,
but it could be simpler and have variable size.
Something like this. (but, I will point out that this core-dumped with
a sig11 on my VM, but it does compile and make the pins)
