Systems and methods are disclosed herein to provide high fan-out signal routing. For example, in accordance with an embodiment of the present invention, a programmable logic device includes a plurality of logic blocks; an interconnect structure adapted to route signals among the logic blocks; and a secondary routing network adapted to route signals among the logic blocks. The secondary routing network may include a plurality of horizontal splines adapted to route signals within the programmable logic device; a plurality of vertical spline taps adapted to route signals within the programmable logic device; a plurality of common interface blocks adapted to route signals between the horizontal splines and the vertical spline taps; and a plurality of horizontal secondary branches adapted to route signals from the vertical spline taps to the logic blocks.
