Hi,

Could somebody please explain the question to me. What are we supposed to do here?

Thanks
Sowmia

Hi Sowmia,

there are different ways to build a circuit using different cell libraries.
You should build a circuit for the given function using the cell libraries {nand_2}.
Your circuit should be as cheap and flat as possible. You also should
specify the costs and depth. In addition, you should compare your
results to the results from the lecture, where we used {exor_2} as
the cell library.

Best,

David

Thanks so much David.
What is the difference between BIB1 and BIB2?

Thanks in advance
Sowmia

Hi Sowmia,


BIB_1 and BIB_2 are just two different library identifiers to distinguish the two sets.

Greetings, Paolo

Hi Paolo,

So, does that mean that BIB_1{exor_2} is the same as BIB_2{exor_2}?

Thanks
Sowmia

Hi,

no, one library is made of nand gates and the other one of exor gates ;)

Paolo

Hi,

would it be enough if I just write down the function? Because I'm not really sure how I'm supposed to define a recursiv circuit.

Cheers,
David

I am confused. Which one?

(Beside the fact that there is no BIB_2{exor_2} in the exercise.)

Hi David,

bib1 = {nand_2) und bib2 = {exor_2}, sie sind unterschiedlich. Jetzt musst bib_1 verwenden, in der Vorlesung wurde (die hier genannte) bib_2 benutzt ;)

Paolo

Die Antwort bezog sich allso auf die Bibliotheken, die in der Aufgabe gegeben waren, nicht auf die Frage?

ja genau
