最近项目要求调试DDR3,所以打算用altera的IP核DDR3 SDRAM CONTROLLER WITH UNIPHY生成的例子工程(example project)进行调试,配置好参数后,生成IP核,但在编译的时候出现如下错误:
Error (129037): Output port OUTCLK on atom "ddr_0002:ddr_inst|ddr_pll0:pll0|uphy_clkbuf_memphy", which is a stratixv_phy_clkbuf primitive, is driving one or more illegal destinations。
Error (129026): Output port OUTCLK of atom "ddr_0002:ddr_inst|ddr_pll0:pll0|uphy_clkbuf_memphy" is driving the I input port of atom "pll_write_clk~output", which is a stratixv_io_obuf primitive. This connection is illegal

有了解的大神吗。芯片使用的是STRATIX V,型号5SGSMD6K2F40C2L,DDR是hynix 的 1600 2GB内存,参数配置严格按照内存DATASHEET。 |
