muxes and pass gates are independent. All permutations of programmable muxes and pass
gates are legal. Vn is connected to the vertical local bus in plane n. Hn is connected to the hori-
zontal local bus in plane n. A local/local turn in plane n is achieved by turning on the two pass
gates connected to Vn and Hn. Up to five simultaneous local/local turns are possible.
The logic cell can be configured in several “modes”. The logic cell flexibility makes the FPGA
architecture well suited to all digital design application areas, see
automatically optimizes designs to utilize the cell flexibility.
