spartan3e和spartan6资源占用对比

最近尝试把fpga从spartan3e-1600转到spartan6-lx16,发觉了一些不同。

  • xc3s1600e
  • Number of occupied Slices 402 of 14,752(2%)
  • xc6slx16
  • Number of occupied Slices 164 of 2,278(7%)

貌似这么一看spartan6如果要2%,那么需要有6018个slices,大致对应xc6slx45。也就是spartan6的slices大致是spartan3的一半就同级别。

  • xc3s250e(2,448)== xc6slx9(1,430)
  • xc3s500e(4,656)== xc6slx16(2,278)
  • xc3s1200e(8,672)== xc6slx25(3,758)
  • xc3s1600e(14,752) == xc6slx45(6,822)
