That should make an adder. No problem.
However, unless I'm missing something about the syntax, I can't seem to use
a simple if...else..then construct without a "begin:<identifier>" being
required. The above instantiates entities with names like:
BIT[0].USELESS.x
BIT[1].USELESS.x
BIT[2].USELESS.x
BIT[3].USELESS.x
....etc.
What I would love to see is:
BIT[0].x
BIT[1].x
BIT[2].x
BIT[3].x
....etc.
Where have I gone astray?
Thanks,
