Hello All, 

 

I have been riding the struggle bus on trying to implement a carry skip adder (carry bypass adder) utilizing a ripple carry chain with multiplexers. I have attached my circuit design below, hopefully it is good enough to read. My issue is that I have no idea what parameters each MUX is to be set to. The (ab) inputs are simple binary 0 or 1 depending on the sum of each ripple. I have also attached the compilation report. If anyone can help I would be grateful and I Thank You in advance.

The pictures are far to small to see anything. 

Is there any reason you are using schematics rather than HDL? Do you have a testbench for this code (you can covert your design to HDL, then simulate).
