Abstract
At least one method, apparatus and system disclosed involves circuit layout for an integrated circuit device. A design for an integrated circuit device is received. The design comprises a functional cell. A first substitute functional cell for a first value of shift of a set of routing tracks respective to the boundary of the functional cell is provided. The first substitute functional cell comprises at least one pin moved by an amount of the first value. A determination is made as to whether an amount of shift of the set of routing tracks corresponds to the first value. The functional cell is replaced with the first substitute functional cell in response to a determination that the amount of shift of the set of routing tracks corresponds to the first value.
