Tie-high and tie-low are used to connect the transistors of the gate by using either the power or the ground. The gates are connected using the power or ground then it can be turned off and on due to the power bounce from the ground. The cells are used to STOP the bouncing and easy from of the current from one CELL to ANOTHER. These cells are required VDD that connects to the tie-high cell as there is a power supply that is high and tie-low gets connected to Vss. This connection gets ESTABLISHED and the transistors function properly without the need of any ground bounce occurring in any cell.
