Abstract(in English) | A macro-block of FPGAs is a set preplaced and prerouted logic-blocks which can imprement a logic function such as an adder or a multiplier. Macro-blocks are indispensable to increase the clock freqency and also logic-block utilization of an FPGA chip. This paper proposes a simultaneous placement and grobal routing algorithm for FPGAs with macro-blocks. The algorithm consists of top-down partitioning and bottom-up combining. The top-down partitioning phase is based on hierarchical bipartitioning of a layout region and a set of macro-block. If there exist connections between bipartitioned macroblock sets, pseudo-pins are introduced to perserve the connections. In this phase rough information for macro-block placement and global routing can be obtained. The Bottom-up combining phase combines partitioned layout regions and macro-blocks and determines datailed placement. The experimental results demonstrate the efficiency and effectiveness of the algorithm. |
