designing of skewed inverters

[smiley_09]

How will I use either a high skew or low skew inverter in my design while writing a RTL code?

While writing RTL code, don't take the skew into consideration. It does not make sense. Skew will be considered in later phases of the front end flow.

The timing between any path is for rise_path vrs fall_path. The ideal situation would be the gates are sized in such a way that rise_delay = fall_delay. this rarely happens because of the stacking effect and other design considerations. The skewed inverters are used at the timing analysis level with parasitics to try to make the rise_fall and fall_paths as equal as possible.
