Abstract

An FPCA includes a scheme for peripheral routing that provides symmetrical routing across its entire area including the periphery by incorporating peripheral routing lines of equal length that are symmetrically deflected orthogonally. The symmetrical peripheral routing lines are connected to switch boxes and connection boxes at the periphery for maintaining constant routing channel width.
