Techniques and mechanisms for providing embedded Input/Output (IO) blocks in a floor plan of a semiconductor device are provided, where the embedded IO blocks constitute partial columns (i.e., they do not extend from the bottom through to the top of the semiconductor device). In some embodiments, the partial column IO banks are skewed away from one another. In some embodiments, the partial column IO banks are located away from the center of the semiconductor device. Techniques and mechanisms for implementing symmetrical package routing using skewed partial column IO banks are also provided.
