英文摘要： The Programmable GRM interconnect architecture is the most important technology from ordinary FPGA to platform-FPGA. This project presents a CAD evaluation software system for the optimization of platform-FPGA's complex interconnect architecture. The software is based on a placement algorithm which can efficiently process various types of programmable logic block, and a routing algorithm which can represent the complex driving relationships contained in GRMs and utilize routing resources more efficiently. Comparing with the traditional methods, this software is 12 to 500 times faster, and shows a higher evaluation efficiency and a better evaluation quality. Some experiment results have been published in International Conference on FPL2011，foreign experts say our paper was interesting and the work commendable. This project has also successfully developed a prototype platform-FPGA chip guided by the above software. The chip includes 128 CLBs, 8 multipliers DSPs, and 8 Block RAMs. It's GRM architecture is a IP-immersion architecture, introducing more flexibility and efficiency. The test results show that all kind functions of this chip could work correctly, and ensure operation at clock rates exceeding 200 MHz. Our results lead to a good beginning for platform-FPGA as an embedded IP core to the SOC products application successful. It can fill in the domestic gap, and lay a theoretical foundation for the sustainable development of series platform-FPGAs to be made in China. Our work have been obtained 7 authorized Chinese invention patents, 8 registered patents, and an integrated circuit layout-design registered certificate. We have published 22 research papers. Among them, 17 papers have been indexed by EI Compendex.
