fabric bitstream

[YazanBaddour]

hello for my fabric i am using K=4 , N = 2 ,CLB.I = 6 ,CLB.O=2 L=4 ,Fs=3 a fabric size 2x2 i went with the same fabric in K4_N4_tileable_40nm (just changed the N value ) and applied the changes there, but for a fabric of 2x2 i still get a long bitstream around 900 for a simple module and i am trying to reduce the length of bitstream is there a way i could simplify my fabric more (note i reached a 100% block utilization) i tried decreasing the route chan_width the bitstream length decreased until it couldn't route anymore. Am i missing something is there any example for even a simpler fabric than this?
thank you!
