According to one embodiment of the invention, a method for designing an
integrated circuit is provided. The method includes providing a first transistor
in a first logic path. The first transistor has a first contact, a first gate length
and a first contact to gate centerline spacing. The method also includes providing
a second transistor in a second logic path. The second transistor has a second
contact, a second gate length and a second contact to gate centerline spacing.
The first contact to gate centerline spacing is substantially equal to the second
contact to gate centerline spacing. The method also includes selecting a different
gate length for the first gate length using a predetermined design criterion.
