What are tiehi and tielo cells?

NAADHAN

Hi all,

Please can any one explain me what are 'tiehi' and 'tielo' cells ? and how are they used in designing ?

 

 

Thanks & Regards,

  • Let's say you need to do an ECO with only one metal mask in order to change a 0 to a 1 on the input of one of your combinatorial gates, but you only have one tie down cell available. If this tie down cell was designed such that you can easily change its function from 0 to 1 by using only one metal layer, then that would be a cost effective change for a localized ECO.
