    Effect of adding an BUF/INV in physical Design on LEC

    Hi all,

    Can anyone tell that what will be the effect of adding BUFs in data path for timing optimization on LEC. Will it show any LEC violations ?

    Thanks

    Not if they're inserted correctly.

    A buffer will never change the functionality, it has no effect on LEC. An inverter does change the functionality, but the tools are smart enough to add/remove a 2nd inverter to keep the functionality the same.
    Really, I am not Sam.
