FPGA片外存储器ddr2之DQSn引脚的分析 对于ddr2的DQSn这个引脚的使用和不使用的情况,我做了一次实验。 先说明一些情况,我手中的arria ii gx的芯片,芯片上是有专门给ddr2上DQSn引脚的配置引脚。可是cyclone 系列的芯片是没有DQSn引脚的。我说的DQSn引脚是FPGA芯片上专门留给ddr2的引脚。无论看芯片手册,还是引脚...
board and am trying to add a DDR3 UniPHY controller. All is fine until I get to the fitter which gives me the error: error (176718): pin memory_mem_dqs_n[0] uses pseudo-differential output node rootport_fifo_qsys:u0|rootport_fifo_qsys_mem_if_ddr3_emif_0:mem_if_ddr3_emif_0|...
