FPGA布線通道分布對面積效率的影響研究

The Research of Area-Efficiency for the Routing Channel Distribution in FPGAs

  • 摘要: 該文提出了現(xiàn)場可編程門陣列(FPGA)布線通道不均勻分布對芯片面積的影響。引入幾個典型的數(shù)學分布函數(shù)(高斯,正弦和三角分布),實現(xiàn)通道容量隨函數(shù)分布變化的新FPGA結構。將這些結構的FPGA與傳統(tǒng)的布線通道均勻分布的FPGA作比較,結果表明按照數(shù)學分布變化的布線通道分布結構比均勻分布情況下的面積效率要高。亦即通道分布的變化趨勢是峰值位置位于芯片中央,即通道容量最大,從中間位置向邊緣按函數(shù)變化趨勢逐漸變小。
