A Self-Adapting Multi-Kernel Controllers Generating and Placing Method for Short System Cycle

For large layout SOC design, one centralized controller easily brings on so long control wires that system cycle doesn´t satisfy timing constraint. This paper proposes a self-adapting multi-kernel controllers generating and placing method. According to different timing constraint, it partitions the control points into different number groups, then generates a local controller for each group and places them on the optimal positions. Thereby control wire length of critical path is reduced, making system cycle satisfy timing constraint. Compared with technique using one centralized controller, system cycle reduces 9.2%
