    Fix Cadence XOR gate schematic 6 dias left
    VERIFICADO

    I have a very simple Cadence schematic and layout I have designed of an XOR gate. For some reason the nest lists do not match in the LVS check. I cannot figure out this simple task because I am new to the process. The layout cannot change but corrections can be applied and the entire schematic can change to make the proper corrections to match the layout.
