FPGA packages have maximum size constraints much larger than the number of IO pins. The resulting IO bottleneck during circuit partitioning means more required packages and more ordinary signal wires crossing between the packages. This cuts more critical timing paths between packages and drastically decreases the circuit operational frequency. In this paper, a bottom-up circuit partitioning method with cone structures is presented. The solution can minimize the delay of critical paths that slow down the circuit without changing the number of partitioned packages
