Hi, 

1) How can extend an output with zeros in Quartus ii (Schematic / Block)?  

2) How can I make a flag named 'zero' to check if an output is zero? 

Thank you!

1. Use named association - tie unused bits to ground 

2. NOR all of the bits.

I got the second but, the first I did not find it, Can you specify the name and the place where I can find it more? And another Q please, how can I negate a 32-bit input? Thanks again.
