  • 1) is your design a block or chip ??
    i) does your design shows any process antenna violations ??

    2) does your ECO net-list has any such changes ??
    Do you know the net name & buffer , inverters, nand type ??

    Once final Q. are you undergoing any training classes or the above talk was your challenge ??
    Please let me know !!
