Hello,

I'm receiving the "Couldn't Merge" message on the AUTOREGINPUT - why? How to solve? Why happens? What exactly "couldn't Merge"?

Thank you!

It means you have two (or more) instances creating an output e.g. "output [1] example" and "output [6] example", and when verilog-mode makes a AUTOWIRE for "example" it can't make a declaration e.g. "wire [1,6] example" is not legal or not easy to figure out. Manually declare the wire.
