David,
Normally when a clk turns into a sine wave it is becasue the capacitive load is much greater than what can be provided by the driving gate.  You would need to either change
the drive gate to one with higher current output or use several gates to drive the 32 loads.  This sounds like a bad hardware design rather than a poor layout.

Thanks, David Plentovich
