description
In this lab, I'll be designing and simulating some basic logic circuits.
Prelab:
In the prelab, I worked on tutorial 4. I first created the schematic of the NAND gate and created its symbol as shown:
Next, I created the simulator schematic and ran it for the following results:
I did the layout next and extracted so I could get the LVS:
Finally, I changed the LVS rules to get the following error message:
Lab Main Content:
Since the NAND gate was done in the prelab portion, this section will focus strictly on the XOR and the full adder.
XOR Schematic and Symbol:
XOR simulator circuit with results:
As you can see, the output is high when the inputs are opposites, proving the XOR works.
Layout, DRC, and LVS:
