Altera Stratix-III上使用Megawizard产生的ALTMEMPHY在synthesis时报错

chlor

我使用Quartus-II的Megawizard产生了DDR SDRAM的PHY IP，即ALTMEMPHY，集成我的设计中后compiler没有问题，但是当synthesis时报如下错误，我都查了好久了也找不出问题所在，哪位高手有过经验的请不吝赐教，谢谢！

没有人知道么，自己顶一下

chlor

顶起来，这个问题有点急

你查查是不是管脚分配的问题。

搞定了，谢谢楼上的。
是因为产生的ALTMEMPHY时有个tcl会配置管脚，而我设计中top层的管脚名与tcl中的命名不一致，没配上。

我也遇到同样问题，期待答案！
