8 bit ALU design

design an 8-bit ALU that takes two signed 8-bit numbers and based upon the opcode specified by s2 s1 s0 performs one of the following functions

ALU control input Function:

s2 s1 s0:

0 0 0 AND

0 0 1 OR

0 1 0 Add

1 1 0 Subtract

1 1 1 Set on less than

The function Set on Less than performs the following function:

If A < B then result =1 otherwise result = 0

ALU also should have an output that is one whenever the result is equal to zero

( make sure you have to do your design on magic software program on linux [url removed, login to view] )

You should turn in the magic layouts for each of your subcells and the circuit diagrams for them. For determining the critical path please turn in the IRSIM results for the circuit failing to operate at a delay just smaller than the critical path, and a simulation showing the circuit functioning correctly at the critical delay.
