Abstract :
The logic blocks of most FPGAs contain clusters of lookup tables and flip-flops yet little is known about good choices for key parameters. How many lookup tables should a cluster contain, how should FPGA routing flexibility change as cluster size changes, and how many inputs should programmable routing provide each cluster?
