我用的是的 EP1C120Q240C8 。
我想测试一下 RCE-01（Red Cyclone Extension） 上的四位七段数码管，结果发现四位七段数码管的FPGA对应的管脚号与主开发板RCM上的Flash的地址信号完全一样，所以我在分配。在 compilation 的后，提示错误：
Error: Can't place node SEVEN_SEG_PIO[15] in location PAD_80 because location already occupied by node FLASH_A[8]
Error: Can't place node SEVEN_SEG_PIO[14] in location PAD_112 because location already occupied by node FLASH_A[16]

Error: Can't place node SEVEN_SEG_PIO[0] in location PAD_110 because location already occupied by node FLASH_A[20]
另外：这个四位七段数码管每个管有个使能信号LED_ANi (i=0,1,2,3)(低电平有效)，而LED_j(j=A,B,B,D,E,F,G,DP)是公用的，既然管脚不能冲突，那我如何让它们复用？？
请高人指点，谢谢！ |
