Error: M4K memory block WYSIWYG primitive "lpm_ram_dp0:inst6|altsyncram:altsyncram_component|altsyncram_4p22:auto_generated|ram_block1a3" utilizes the dual-port dual-clock mode. However, this mode is not supported in Cyclone II device family in this version of Quartus II software. Please refer to the Cyclone II FPGA Family Errata Sheet for more information on this feature.
译文如下:错误:内存块的M4K所见即所得原始的“lpm_ram_dp0:auto_generated | ram_block1a3”采用了双口双时钟模式。然而,这种模式是不支持的Cyclone II器件系列在这个版本的Quartus II软件。请参阅更多有关此功能的信息与Cyclone II FPGA系列的勘误表。
但是我的软件是9.0的啊 quartus;我看了Cyclone II Device Handbook,支持双口RAM啊! 为什么会出错呢啊! 请高手解答啊!谢谢啊!
