Dear all,

How to optimize this circuit?

Thanks for your help!!!!

how to optimize a circuit

you can draw a truth table and optimize

another methode is to use DC tool. The tool can automatically optimize combinational logic with command " set_structure -boolean true".

set_structure true is the default option when compiling with DC, you can set_flatten true before compling and you'll get a two-level logic in structure sum-of-product

Thanks David for posting the paper.

Does any body have some good books regarding logic optimization??

thanks

The logic for O2 in the above circuit will not be equal after adding the redundant wire.
I hope the inputs are to be changed....
does anybody solved this one!!! if so then plz share with us
thanks
