Height of standard cells

Post by vikramrajput » Mon Apr 06, 2015 9:43 pm

Hi there,

As we all know that the height of the standard cells in .lib file is same for all the cells. Can anyone tell me the exact reason and the importance / benefits of having same height ??

Standard cells in a library are rectangular with the same height but different widths. The key aspect with these libraries is that they are of a fixed height, which enables them to be placed in rows, easing the process of automated digital layout. The cells are typically optimized full-custom layouts, which minimize delays and area.
