创建INTERNAL_VREF约束,只需要将I/O bank拖到对应参考电压的文件夹中即可;拖到NONE中表示撤销参考电压设置。该设置对应着约束命令,需要保存到XDC约束文件中,示例如下: set_property INTERNAL_VREF 0.75 [get_iobanks 14] set_property INTERNAL_VREF 0.675 [get_iobanks 15]...

一般情况,VREF需要接到外部参考电压,例如DDR3L为1.35V。如果端口不够用,可以使用内部参考电压,那么端口 E3和N3 就可以当输入来用。 在Device Constraints窗口中选择“Internal VREF”,列出了该芯片支持的内部参考电压,NONE文件夹中的I/O bank表示没有设置INTERNAL_VREF约束。 创建INTERNAL_VREF约束,只需要将I/O bank...
